'''ThinkPad''' <!-- Use this capitalization throughout this article --> is a line of business-oriented [[laptop]] and [[Tablet computer|tablet computers]] produced since 1992. It was originally designed, created and manufactured by the American [[IBM|International Business Machines]] (IBM) Corporation. IBM [[Acquisition of the IBM PC business by Lenovo|sold its PC business]] to the Chinese company [[Lenovo]] in 2005 and since 2007 all ThinkPad models have been manufactured by them.<ref>{{cite web |url=https://news.lenovo.com/pressroom/press-releases/lenovo-marks-decade-success-since-acquisition-ibms-pc-business/ |title=Lenovo Marks Decade of Success Since Acquisition of IBM's PC Business - Lenovo StoryHub |publisher=News.lenovo.com |date=2015-04-30 |accessdate=2022-03-16 |archive-date=28 November 2021 |archive-url=https://web.archive.org/web/20211128205542/https://news.lenovo.com/pressroom/press-releases/lenovo-marks-decade-success-since-acquisition-ibms-pc-business/ |url-status=live }}</ref>

[[File:Original IBM ThinkPad.jpg|left|thumb|A 1980s-era IBM THINK notepad (above), which inspired the laptop name, and the notepad refill information (below)]]

The name "ThinkPad" was a product of IBM's corporate history and culture. [[Thomas J. Watson]] Sr. first introduced "[[Think (slogan)|Think]]" as an IBM slogan in the 1920s. With every minicomputer and mainframe IBM installed (almost all were leased – not sold), a plastic sign with the text "Think" printed on an aluminum plate was placed atop the operator's console.<ref>{{cite web |url=https://americanhistory.si.edu/collections/nmah_690192 |title=IBM Think Sign |access-date=24 August 2024}}</ref>

For decades, IBM had also distributed small notepads with the word "THINK" emblazoned on their cover to customers and employees.<ref>{{cite web |url=http://www.osnews.com/story/22274/The_History_of_the_ThinkPad_Name |title=The History of the ThinkPad Name |access-date=2 October 2009 |archive-date=3 November 2011 |archive-url=https://web.archive.org/web/20111103204604/http://www.osnews.com/story/22274/The_History_of_the_ThinkPad_Name |url-status=live |first=Thom |last=Holwerda |date=2 October 2009 }}</ref> The name "ThinkPad" was suggested by IBM employee Denny Wainwright, who had one such notepad in his pocket.<ref name="Hamm">{{cite book |last1=Hamm |first1=Steve |title=The race for perfect : inside the quest to design the ultimate portable computer |date=2009 |publisher=McGraw-Hill |location=New York |isbn=9780071606110}}</ref><ref name="lenovo">{{cite web|date=December 2001|title=IBM Highlights, 1990 -1995|url=http://www-03.ibm.com/ibm/history/documents/pdf/1990-1995.pdf|access-date=11 May 2008|publisher=[[International Business Machines|IBM]]|archive-date=16 May 2017|archive-url=https://web.archive.org/web/20170516135616/http://www-03.ibm.com/ibm/history/documents/pdf/1990-1995.pdf|url-status=dead}}</ref> The name was opposed by the IBM corporate naming committee as all the names for IBM computers were numeric at that time, but "ThinkPad" was kept due to praise from journalists and the public.<ref>{{cite web |title=A Rose by any other Name |url=http://thinkpads.com/Genesis3.htm |archive-url=https://web.archive.org/web/20070922123604/http://thinkpads.com/Genesis3.htm |archive-date=22 September 2007}}</ref>

This 1990–1992 "pre-Internet" collaboration between Italy and Japan was facilitated by a special Sony digital communications system that transmitted high-res images over telephone lines.

IBM marketed the ThinkPad creatively, through methods such as early customer pilot programs, numerous pre-launch announcements, and an extensive loaner program designed to showcase the product's strengths and weaknesses, including loaning a machine to archaeologists excavating the ancient Egyptian city of [[Leontopolis]]. The resulting report documented the ThinkPad's excellent performance under difficult conditions; "The ThinkPad is an impressive machine, rugged enough to be used without special care in the worst conditions Egypt has to offer."<ref name="Hamm" /> The positive critical and commercial reception of the ThinkPad played a key part in reversing IBM's fortunes.<ref>{{cite web | url=https://www.nytimes.com/1993/06/23/business/notebooks-may-hold-key-to-ibm-s-revival.html | title=Notebooks May Hold Key to I.B.M.'s Revival | work=The New York Times | date=23 June 1993 | last1=Lohr | first1=Steve }}</ref>

===Acquisition by Lenovo===
[[File:Yamato lab japan.jpg|thumb|IBM/Lenovo's Yamato Lab where the Think line of products is developed|left]]{{Main|Acquisition of the IBM PC business by Lenovo}}
In 2005, Lenovo purchased the IBM personal computer business and the ThinkPad as a flagship brand along with it. Lenovo founder [[Liu Chuanzhi]] said, "We benefited in three ways from the IBM acquisition. We got the ThinkPad brand, IBM's more advanced PC manufacturing technology and the company's international resources, such as its global sales channels and operation teams. These three elements have shored up our sales revenue in the past several years."<ref name=Hamm/>

Although Lenovo acquired the right to use the IBM brand name for five years after it acquired IBM's personal computer business, it was only used for three years. In 2012 Lenovo manufactured and marketed Think-branded products while IBM was mostly responsible for overseeing servicing and repairs for them. At that time both IBM and Lenovo played a key role in the design of their "Think" branded products.<ref>{{cite web |title=IBM and Lenovo |url=https://www.ibm.com/ibm/us/en/pcannouncement/ |website=IBM Archives |date=8 October 2012 |access-date=30 August 2021 |archive-date=30 August 2021 |archive-url=https://web.archive.org/web/20210830161211/https://www.ibm.com/ibm/us/en/pcannouncement/ |url-status=live }}</ref>

===Manufacturing===
The majority of ThinkPad computers since the 2005 acquisition of the brand by Lenovo have been made in Mexico, Slovakia, India, and China. Lenovo employs ~300 people at a combined manufacturing and distribution center near its American headquarters. Each device made in this facility is labeled with a red-white-and-blue sticker proclaiming "[[Whitsett, North Carolina]]."<ref name="Ranii">{{cite news|last=Ranii|first=David|date=4 February 2015|title=After 100 million sold, Lenovo's ThinkPad laptop still going strong|newspaper=The News & Observer|url=http://www.newsobserver.com/news/technology/article10863791.html|access-date=10 March 2015|archive-date=11 March 2015|archive-url=https://web.archive.org/web/20150311192422/http://www.newsobserver.com/news/technology/article10863791.html|url-status=live}}</ref>

[[File:ThinkPad T20.jpg|thumb|A typical IBM design example (2000's [[ThinkPad T20]])]]

The appearance of the ThinkPad has remained very similar throughout the entire lifetime of the brand. Almost all models are solid black inside and out, with a boxy case design. Some newer Lenovo models incorporate more curved lines. Many ThinkPads utilize magnesium, [[carbon fiber]] reinforced plastic, or [[titanium]] in their chassis.

The industrial design concept was created in 1990 by Italy-based designer [[Richard Sapper]], a corporate design consultant of IBM and, since 2005, Lenovo.<ref name="Sakakibara" /><ref name="Golden">{{cite web |first=Peter |last=Golden |date=1 January 1999|title=Big Blue's big adventure|url=http://www.edn.com/electronics-news/4357642/Big-Blue-s-big-adventure|publisher=EDN Network|access-date=22 July 2013|archive-date=3 April 2015|archive-url=https://web.archive.org/web/20150403033315/http://www.edn.com/electronics-news/4357642/Big-Blue-s-big-adventure|url-status=live}}</ref><ref name="Hardy" /><ref name="Webb2002">{{cite book |last1=Webb |first1=Michael |editor1-last=Bartolucci |editor1-first=Marisa |editor2-first=Raul |editor2-last=Cabra |title=Richard Sapper |date=2002 |publisher=Chronicle Books |location=San Francisco |isbn=9780811832823}}</ref><ref name="Hamm2008">{{cite news |last1=Hamm |first1=Steve |title=Richard Sapper: Fifty Years at the Drawing Board |url=https://www.bloomberg.com/news/articles/2008-01-09/richard-sapper-fifty-years-at-the-drawing-board |access-date=20 March 2023 |work=Bloomberg.com |date=10 January 2008 |archive-url=https://web.archive.org/web/20171006062411/https://www.bloomberg.com/news/articles/2008-01-09/richard-sapper-fifty-years-at-the-drawing-board |archive-date=6 October 2017 |language=en |url-access=subscription |url-status=live}}</ref> The design was based on the concept of a traditional Japanese ''[[bento]]'' lunchbox, which revealed its nature only after being opened.<ref name="Hamm" /><ref name="Sakakibara" /><ref name="Hardy" /> According to later interviews with Sapper, he also characterized the simple ThinkPad form to be as elementary as a simple, black cigar box and with similar proportions, with the same observation that it offers a 'surprise' when opened.<ref name="Webb2002" /><ref name="rsapper-lenovo" />

== Features and technologies ==
{{Multiple issues|section=yes|
{{Promotional section|date=February 2025}}
{{More citations needed section|date=February 2025}}
}}
Several unique features have appeared in the ThinkPad line, like drive protection, a TrackPoint, or [[Trusted Platform Module]] chips.

While few features remain unique to the series, several laptop technologies originated on ThinkPads:<ref name="Hamm" />

===Current===
* '''Lenovo Vantage'''
{{Main|ThinkVantage Technologies}}

Earlier known as "IBM Access", later "ThinkVantage", the Lenovo Vantage is a suite of computer management applications. This software can give additional support for system management (backup, encrypting, system drivers installation and upgrade, system monitoring and others). Currently, some old features have been replaced by internal Windows 10/11 features.

*'''TPM chips'''
IBM was the first company that supported a [[Trusted Platform Module]] (TPM).<ref>{{cite web | url = https://www.trustedcomputinggroup.org/wp-content/uploads/Vendor_ID_Registry_0-8_clean.pdf | title = TCG Vendor ID Registry | date = September 23, 2015 | access-date = October 27, 2016 | archive-date = 28 October 2016 | archive-url = https://web.archive.org/web/20161028083456/https://www.trustedcomputinggroup.org/wp-content/uploads/Vendor_ID_Registry_0-8_clean.pdf | url-status = live }}</ref> Modern ThinkPads still have this feature.

*'''ThinkShutter'''
''ThinkShutter'' is the branding of a [[webcam]] privacy shutter present in some ThinkPad [[laptop|notebook computers]]. It is a simple mechanical sliding cover that allows the user to obstruct the webcam's view.<ref>{{cite news| title=Lenovo's new laptops have clever built-in webcam covers so you can finally ditch the piece of tape| website=[[Business Insider]]| url=https://www.businessinsider.com/lenovo-thinkshutter-laptops-webcam-covers-2018-1| access-date=3 September 2020| archive-date=6 September 2020| archive-url=https://web.archive.org/web/20200906062849/https://www.businessinsider.com/lenovo-thinkshutter-laptops-webcam-covers-2018-1| url-status=live |first=Avery |last=Hartmans |date=4 January 2018 |url-access=registration }}</ref> Some add-on webcams and other laptop brands provide a similar feature. [[IdeaPad]] notebooks carry the TrueBlock branding for their privacy shutters.<ref>{{cite web | title = IdeaPad L340 Gaming Laptop | url=https://www.lenovo.com/us/en/p/laptops/ideapad/ideapad-300/lenovo-ideapad-l340-17iwl/88ipl301160 |quote="The IdeaPad L340’s HD webcam makes video chats and conference calls a breeze. It also has TrueBlock Privacy Shutter, a switch for you to physically close your webcam and help keep your personal life private."}}</ref> These mechanical sliders are present on Lenovo's [[Lenovo LOQ|LOQ]] series of laptops as well as a digital version on most of Lenovo's [[Lenovo Legion|Legion]] gaming laptops.

*'''Spill-resistant keyboards'''
All ThinkPad models have a keyboard membrane and drain holes (L series, P series, E series, T series, X series, X1 series, and Z series models), and some have a solid rubber or plastic membrane (like L series, W series, X1 series, and current T and X series), without draining holes.

[[File:ThinkPad X1 Carbon Japanese Keyboard.jpg|thumb|Touchpad + TrackPoint combination; modern keyboard]]
*'''UltraNav'''
The first ThinkPad 700 was equipped with the signature [[TrackPoint]] red dot pointing stick invented by [[Ted Selker]]. By 2000 the [[trackpad]] pointer had become more popular for laptops due to innovations by [[Synaptics]] so IBM introduced UltraNav as a complementary combination of TrackPoint and TouchPad designed by Dave Sawin, Hiroaki Yasuda, Fusanobo Nakamura, and Mitsuo Horiuchi to please all users.<ref name="auto" />

*'''A [[roll cage]] frame''' and stainless steel hinges with 180° or 360° opening angle
The "roll cage" is an internal frame, designed to minimize motherboard flex (current P series and T##p series) or magnesium composite case (all other hi-end models). The display modules lack magnesium frames, and some 2012-2016 models have a common issue with a cracked plastic lid. The 180° hinges are typical, the 360° hinges are a [[ThinkPad Yoga|Yoga line]] basic feature.

*'''OLED screens'''
Introduced in 2016 as a high-end display option for some models.

*'''Active Protection System'''
[[Active hard-drive protection|Hard-drive protection]] for some ThinkPad models that still use the 2.5" drive bay; These systems use an [[accelerometer]] sensor to detect when a ThinkPad is falling and shut down the hard disk drive to prevent damage.

*'''Biometric fingerprint reader''' and '''NFC [[smart card]] reader''' options
The fingerprint reader was introduced as an option by IBM in 2004. ThinkPads were one of the first laptops to include this feature.

*Internal '''[[WWAN]] modules''' and '''Wi-Fi 3x3 [[MIMO]]'''
The [[Mobile broadband]] support is a common feature for most of the actual ThinkPad models after 2006; the support of 3x3 MIMO is a common feature for most high-end models.

Some additional features (dock stations, UltraBay, accessories support) were listed in the [[#Accessories|Accessories]] section.

===Past===

*'''ThinkLight'''
External keyboard light, replaced by internal backlight; is an LED light located at the top of the LCD screen which illuminates the keyboard from above.

*'''Power Bridge'''
Some E, L, T, X, W (only W550s), and P (only P##s) series ThinkPads feature (for some 2013-2018 models) — internal secondary battery (as a succession of secondary UltraBay battery) that support a hot-swapping of primary battery.

[[File:Lenovo-ThinkPad-Keyboard.JPG|thumb|ThinkPad 7-row keyboard, replaced with a newer 'island' design in 2012. For user convenience, buttons with the same functions are located both above and below the touchpad.]]

*'''7-row Keyboards'''
:'''Original IBM keyboard design (1992–2012)''' — The original keyboard was offered in the ThinkPad line until 2012, when it was swapped out for the chiclet-style keyboard now used today.
::'''IBM TrackWrite keyboard design''' — A unique keyboard designed by John Karidis introduced by IBM in 1995, used in the ThinkPad 701 series. When the machine is closed the keyboard is folded inwards, making the machine more compact. However, when the machine is open and in use, it slides out, giving the user a normal-sized keyboard. That keyboard, referred to as a [[IBM ThinkPad Butterfly keyboard|butterfly keyboard]], which is widely considered a design masterpiece and is in the permanent collection of the [[Museum of Modern Art]] in New York City.<ref>{{cite web|url=http://www.eweek.com/c/a/Desktops-and-Notebooks/Lenovo-ThinkPad-Tablet-2-X1-Carbon-Debut-at-MoMA-Anniversary-Bash-211203/|archive-url=https://archive.today/20130629035043/http://www.eweek.com/c/a/Desktops-and-Notebooks/Lenovo-ThinkPad-Tablet-2-X1-Carbon-Debut-at-MoMA-Anniversary-Bash-211203/|url-status=dead|archive-date=29 June 2013|title=Lenovo ThinkPad Tablet 2, X1 Carbon Debut at MoMA Anniversary Bash – Desktops and Notebooks & Reviews – eWeek.com}}</ref><ref name="MoMA Collection">{{cite web|date=30 September 2010|title=MoMA The Collection: Richard Sapper, Sam Lucente, Robert Tennant and IBM Corporation, ThinkPad 701 Portable Computer, 1995|url=http://www.moma.org/collection/object.php?object_id=2168|publisher=The Museum of Modern Art|access-date=22 July 2013|archive-date=20 September 2013|archive-url=https://web.archive.org/web/20130920032518/http://www.moma.org/collection/object.php?object_id=2168|url-status=live}}</ref>

:The ThinkPad 760 series also included an unusual keyboard design; the keyboard was elevated by two arms riding on small rails on the side of the screen, tilting the keyboard to achieve a more ergonomic design.

The keyboard design was replaced by the '''Chiclet style keyboard (2012-current)''' in 2012. The chiclet-style keyboard does not support the ThinkLight for illumination, instead using a keyboard backlight. Some ThinkPad models during the intermission period between the classic IBM design and the Lenovo chiclet design could be outfitted with both the backlit chiclet-style keyboard and the ThinkLight.

*'''FlexView [[Advanced Fringe Field Switching|advanced fringe field switching]] or [[Liquid-crystal display#In-plane switching (IPS)|in-plane switching]] screens'''
The introduced in 2004 line of hi-end displays with wide view angles<ref>{{cite web|title=IBM ThinkPad T42 Review (pics, specs)|url=http://www.notebookreview.com/notebookreview/ibm-thinkpad-t42-review-pics-specs/|access-date=2021-05-19|website=Notebook Review |archive-date=19 May 2021|archive-url=https://web.archive.org/web/20210519093922/http://www.notebookreview.com/notebookreview/ibm-thinkpad-t42-review-pics-specs/|url-status=dead |date=31 August 2004}}</ref> and optional high resolution (up to 15" 1600x1200<ref>{{cite web|last=Leitner|first=J.

Partially dropped in 2008 (after the partial defunct of [[BOE Technology|BOE-Hydis]] display supplier), and reintroduced as an ordinary IPS screen option in 2013.

===Batteries===
Some ThinkPad laptops (such as the X230/X230t, T430s/T430 and T530/W530, all from 2012) block third-party batteries. Lenovo calls this feature "Battery Safeguard". It was first introduced on some models in May 2012. Laptops with this feature scan for security chips that only ThinkPad-branded batteries contain. Affected ThinkPads flash a message stating "Genuine Lenovo Battery Not Attached" when third-party batteries are used, and the battery will not charge.<ref>{{cite web|first=Sean |last=Hollister |date=16 March 2012|title=Lenovo laptops will reject third-party batteries, starting with ThinkPad Edge in May?|url=https://www.theverge.com/2012/3/16/2878633/lenovo-battery-safeguard-e430-e530-plus|work=The Verge|access-date=16 September 2017|archive-date=7 July 2018|archive-url=https://web.archive.org/web/20180707093222/https://www.theverge.com/2012/3/16/2878633/lenovo-battery-safeguard-e430-e530-plus|url-status=live}}</ref><ref>{{cite web|last=Benchoff |first=Brian |date=11 February 2016|title=Unlocking Thinkpad Batteries|url=https://hackaday.com/2016/02/11/unlocking-thinkpad-batteries/|access-date=16 October 2022|archive-date=16 October 2022|archive-url=https://web.archive.org/web/20221016161458/https://hackaday.com/2016/02/11/unlocking-thinkpad-batteries/|url-status=live}}</ref>

==Operating systems==
The ThinkPad has shipped with [[Microsoft Windows]] from its inception until the present day. Alongside [[IBM PC DOS]], [[Windows 3.1x]] was the default operating system on the original ThinkPad 700.

IBM and Microsoft's joint operating system, known as [[OS/2|Operating System/2]] (OS/2), although not as popular, was also made available as an option from the ThinkPad 700 in 1992, and was officially supported until the T43 in 2005.

The [[IBM ThinkPad Power Series|ThinkPad Power series]] line, sold from 1994 through 1998, was available with [[IBM AIX|AIX]] and [[Oracle Solaris|Solaris]] operating systems.

IBM took its first steps toward ThinkPads with an alternative operating system, when they quietly certified the 390 model for [[SUSE Linux]] in November 1998.<ref>{{cite web |url=https://www.suse.com/nbswebapp/yesBulletin.jsp?bulletinNumber=47948 |title=ThinkPad 390: YES Bulletin 47948 |publisher=SUSE |date=November 25, 1998 |accessdate=November 10, 2021 |archive-date=10 November 2021 |archive-url=https://web.archive.org/web/20211110075440/https://www.suse.com/nbswebapp/yesBulletin.jsp?bulletinNumber=47948 |url-status=live }}</ref> The company released its first [[Linux|Linux-based]] unit with the ThinkPad A20m in July 2000. This model, along with the closely-released A21m, T21, and T22 models, came preinstalled with [[Caldera OpenLinux]].<ref>{{cite press release |url=http://ir.calderasystems.com/wc/form/P1?template=ir/CALD/view_article&Symbol=CALD&first=&ArticleID=SM-CALD-20000620 |archive-url=https://web.archive.org/web/20010523180547/http://ir.calderasystems.com/wc/form/P1?template=ir/CALD/view_article&Symbol=CALD&first=&ArticleID=SM-CALD-20000620 |url-status=dead |archive-date=2001-05-23 |author=<!--Not stated--> |title=Caldera Announces OpenLinux eDesktop Pre-load On Select IBM ThinkPads |location=Orem, Utah |publisher=Caldera Systems, Inc. |date=June 20, 2000 |accessdate=November 9, 2021}}</ref> IBM shifted away from preinstalled Linux on the ThinkPad after 2002, but continued to support other distributions such as [[Red Hat Linux]], [[SUSE Linux Enterprise]], and [[Turbolinux]] using customer installations on A30, A30p, A31p models. This continued through the Lenovo transition with the T60p, until September 2007.<ref>{{cite web |url=https://ide-research.net/papers/04_8_ThinkPad%20A30%20Series%20Brochure.pdf |title=IBM ThinkPad A Series notebooks |publisher=IBM |date=October 2001 |accessdate=November 10, 2021 |archive-date=29 November 2021 |archive-url=https://web.archive.org/web/20211129125805/https://ide-research.net/papers/04_8_ThinkPad%20A30%20Series%20Brochure.pdf |url-status=live }}</ref>

The following year, ThinkPads began shipping with Linux again, when the R61 and T61 were released with SUSE Linux Enterprise as an option.<ref>{{cite web |url=https://www.cnet.com/news/linux-available-on-thinkpad-t61-and-r61 |last=Ogg |first=Erica |title=Linux available on ThinkPad T61 and R61 |date=January 15, 2008 |accessdate=November 10, 2021 |archive-date=10 November 2021 |archive-url=https://web.archive.org/web/20211110075737/https://www.cnet.com/news/linux-available-on-thinkpad-t61-and-r61/ |url-status=live }}</ref> This was short-lived, as Lenovo discontinued that practice in 2009. ThinkPad hardware continued to be certified for Linux.

In 2020, Lenovo shifted into much heavier support of Linux when they announced the ThinkPad X1 Carbon Gen 8, the P1 Gen 2, and the P53 would come with [[Fedora Linux]] as an option.<ref>{{cite web |url=https://www.zdnet.com/article/lenovo-releases-first-fedora-linux-thinkpad-laptop/ |title=Lenovo releases first Fedora Linux ThinkPad laptop |last=Vaughan-Nichols |first=Stephen J. |publisher=ZDNet |date=September 3, 2020 |access-date=November 10, 2021 |archive-date=10 November 2021 |archive-url=https://web.archive.org/web/20211110111049/https://www.zdnet.com/article/lenovo-releases-first-fedora-linux-thinkpad-laptop/ |url-status=live }}</ref> This was the first time that Fedora Linux was made available as a preinstalled option from a major hardware vendor.

A small number of ThinkPads, such as the C14, are preinstalled with Google's [[ChromeOS]], and are essentially ThinkPad-branded Chromebooks. On these devices, ChromeOS is the only officially supported operating system where installation of Windows and other operating systems requires putting the device into developer mode, as is the case with other Chromebooks.{{Citation needed|date=February 2022}}

==Use in space==
[[File:TORU docking system.jpg|thumb|ThinkPads in use aboard the [[International Space Station]], including 760, 770, and A21p models (2004)]]
ThinkPads have been used heavily in space programs. NASA purchased more than 500 ThinkPad 750 laptops for flight qualification, software development, and crew training, and astronaut [[John Glenn]] used ThinkPad laptops on his spaceflight mission [[STS-95]] in 1998.<ref name="ibm.com">{{cite web|url=https://www-03.ibm.com/ibm/history/exhibits/space/space_thinkpad.html|title=IBM Archives: IBM ThinkPads in space|date=23 January 2003|access-date=1 January 2017|archive-date=23 December 2016|archive-url=https://web.archive.org/web/20161223020438/http://www-03.ibm.com/ibm/history/exhibits/space/space_thinkpad.html|url-status=dead}}</ref>

===ThinkPad Yoga (2013–current)===
{{Main|ThinkPad Yoga}}
[[File:ThinkPadYogaTent.jpg|thumb|A ThinkPad Yoga in tent mode]]
The [[ThinkPad Yoga]] is an Ultrabook-class convertible device that functions as both a laptop and tablet computer. The Yoga gets its name from the consumer-oriented IdeaPad Yoga line of computers with the same form factor. The ThinkPad Yoga has a backlit keyboard that flattens when flipped into tablet mode. This was accomplished on 1st generation X1 Yoga with a platform surrounding the keys that rise until level with the keyboard buttons, a locking mechanism that prevents key presses, and feet that pop out to prevent the keyboard from directly resting on flat surfaces. On later X1 Yoga generations, the keys themselves retract in the chassis, so the computer rests on fixed small pads. The touchpad is disabled in this configuration. Lenovo implemented this design in response to complaints about its earlier Yoga 13 and 11 models being awkward to use in tablet mode. A reinforced hinge was required to implement this design. Other than its convertible form factor, the ThinkPad Yoga retains standard ThinkPad features such as a black magnesium-reinforced chassis, an island keyboard, a red TrackPoint, and a large touchpad.<ref name="CNET">{{cite news |title=Hands-on with Lenovo's ThinkPad Yoga |first=Dan |last=Ackerman |url=https://www.cnet.com/reviews/lenovo-thinkpad-yoga-preview/ |publisher=CNET |date=5 September 2013 |access-date=4 October 2013 |archive-date=12 September 2013 |archive-url=https://web.archive.org/web/20130912042346/http://www.cnet.com/laptops/lenovo-thinkpad-yoga/4505-3121_7-35827163.html |url-status=live }}</ref>

===E series (2011–current)===
[[File:Fotos produzidas pelo Senado (26033663483).jpg|thumb|Two E series ThinkPad's (E440)]]
{{Main|ThinkPad E series}}

The E series is a low-cost ThinkPad line, designed for small business mass-market requirements, and currently contains only a 14" and 16" sub-lines. The E series line of laptops replaced Lenovo's Edge series, but somewhere (in some countries) currently offered as both of "ThinkPad Edge/E series" names. The E series also lack metals like magnesium and carbon fibre in their construction which other members of the ThinkPad family enjoy.<ref>{{cite web|url=https://www.lenovo.com/ru/ru/laptops/thinkpad/edge-series/c/edge-series|title=Ноутбуки Thinkpad серии Edge|language=ru|date=28 May 2019|publisher=lenovo.com|access-date=28 May 2019|archive-date=28 May 2019|archive-url=https://web.archive.org/web/20190528095242/https://www.lenovo.com/ru/ru/laptops/thinkpad/edge-series/c/edge-series|url-status=live}}</ref>

===L series (2010–current)===
{{Main|ThinkPad L series}}
The L series replaced the former R series, and is positioned as a mid-range ThinkPad offering with mainstream Intel Core i3/i5/i7 CPUs. The L Series have 3 sub-lines, the long-running 14" and 15.6" (and as launched this line had two models, L412 and the L512 in 2010); and as of 2018 there is also a 13" L380 available, which replaces the ThinkPad 13.

===T series (2000–current)===
[[File:X31 T43 laptop.png|thumb|An [[ultraportable]] [[IBM]] X31 with a ThinkPad T43 notebook]]
{{Main|ThinkPad T series}}

The T series historically had high-end features, such as magnesium alloy roll-cages, high-density IPS screens known as FlexView (discontinued after the T60 series), 7-row keyboards, screen latches, the [[ThinkPad UltraBay|UltraBay]], and [[ThinkLight]]. Models included both 14.1-inch and 15.4-inch displays available in 4:3 and 16:10 aspect ratios.

Since 2012, the entire ThinkPad line was given a complete overhaul, with modifications such as the removal of separate buttons for use with the TrackPoint (xx40 series – 2014, then reintroduced xx50 series – 2015), removal of separate audio control buttons, removal of screen latch, and the removal of LED indicator lights. Models starting from the xx40 series featured a Power Bridge battery system, which had a combination of a lower capacity built-in battery and a higher capacity external battery, enabling the user to switch the external without putting the computer into hibernation. However, beginning with the 2019 xx90 series models, the external battery was removed in favor of a single internal battery. Also, non-widescreen displays are no longer available, with 16:9 aspect ratio as the only remaining choice.

The Tx20 series ThinkPads came in two editions: 15" (T520) or a 14" (T420). These are the last ThinkPads to use the classic 7-row keyboard, with the exception of the [[Lenovo ThinkPad 25th anniversary edition]] released on Oct. 5, 2017, which was based on the [[ThinkPad T series#T470|T470]].<ref>{{cite web |date=2018-04-01|title=The 25th-anniversary ThinkPad: Every laptop should add some retro appeal|url=https://arstechnica.com/gadgets/2018/04/the-25th-anniversary-thinkpad-every-laptop-should-add-some-retro-appeal/|access-date=2022-01-24|website=Ars Technica|language=en-us|archive-date=23 November 2021|archive-url=https://web.archive.org/web/20211123110627/https://arstechnica.com/gadgets/2018/04/the-25th-anniversary-thinkpad-every-laptop-should-add-some-retro-appeal/|url-status=live}}</ref><ref>{{cite web|last=Dignan|first=Larry|title=Lenovo's ThinkPad turns 25: Here are 25 facts to mark the anniversary |date=5 October 2017 |url=https://www.zdnet.com/article/lenovos-thinkpad-turns-25-here-are-25-facts-to-mark-the-anniversary/|access-date=2022-01-24|website=ZDNet|language=en|archive-date=22 November 2021|archive-url=https://web.archive.org/web/20211122165316/https://www.zdnet.com/article/lenovos-thinkpad-turns-25-here-are-25-facts-to-mark-the-anniversary/|url-status=live}}</ref>

Over time, The T series ThinkPad's purpose has changed. Initially, the T series ThinkPad was meant to have high-end business features and carry a 10–20% markup over the other ThinkPads. Starting with the T400, the ThinkPad T series became less of a high-end business laptop and became more suited as a mobile workstation, becoming similar to the W series or P series ThinkPads. Achieving similar performance to the W series, but with a 5–10% smaller profile than the W series ThinkPads. In 2013, the T440 introduced another major shift in The ThinkPad T series. The ThinkPad became more of an overall office machine than a mobile workstation. By today's standards, The ThinkPad T series is thicker than most of its competitors.

===X series (2000–current)===
{{Main|ThinkPad X series|ThinkPad X1 series}}
[[File:ThinkPad_X60_Series_with_Libreboot.jpg|thumb|Two X60 units (Tablet and slim non-Tablet versions) running [[Libreboot]]]]

The X series is the main high-end ultraportable ThinkPad line, offering a lightweight, highly portable laptop with moderate performance. The current sub-lines for the X series includes:
* 12" '''X12''' (detachable tablet);
* 13" '''X13''' (mainstream),
** '''X13 2-in-1''' (convertible sub-line);
* 14" '''X1 Carbon''' (premium sub-line), 
** '''X1 2-in-1''' (premium convertible sub-line),
** '''X9''' '''14''' (premium sub-line);
* 15" '''X9 15''' (premium sub-line);
* 16" '''X1 Fold''' ([[Flexible display|foldable screen]] device).

The daughter line includes the '''X1 Tablet''' (not to be confused with the 2005-2013 X Series tablets).

The mainstream current "workhorse" models is a X13 and X13 Yoga, the 13" successors of the classic discontinued 12" line of Lenovo X Series ThinkPads.

The premium X1 thin-and-light line were the 13.3" ThinkPad models (the X300, X301, and X1) with [[ultrabay|Ultrabay Thin]] CD-ROM and removable battery, but are now replaced by the modern premium X1 series [[ultrabook]] line, such as the X1 Carbon, X1 Yoga, and X1 Nano sub series.

Discontinued mainstream lines such as the 12" X200(s), X201(s), and X220 models could be ordered with all of the high-end ThinkPad features (like TrackPoint, ThinkLight, a 7-row keyboard, a docking port, hot-swappable [[Hard disk drive|HDD]], solid [[magnesium]] case and optional slice battery). The discontinued 12.5" X220 and X230 still featured a roll cage, a ThinkLight, and an optional premium IPS display (the first IPS display on a non-tablet ThinkPad since the T60p), but the 7-row keyboard was offered only with the X220. However, it lacked the lid latch mechanism which was present on the previous X200 and X201 versions. The discontinued slim 12" line contained only X200s and X201s with low power CPUs and high resolution displays, and X230s with low power CPUs. The 12.5" X series ThinkPads (such as X240 and later) had a more simplified design, and last 12" X280 model had only the Trackpoint feature, partially magnesium case and simplified docking port.

The obsolete low-cost 11.6" ([[netbook]] line) X100e and X120e were are all plastic, lacking both the latch and the [[ThinkLight]], and using a variant of the island keyboard (known as [[chiclet keyboard]]) found on the Edge series. The X100e was also offered in red in addition to blue, and white in some countries.<ref>{{cite web |url=http://www.clonedinchina.com/2010/01/white-thinkpad-x100e-unboxed.html |title=White Thinkpad X100e unboxed |archive-url=https://web.archive.org/web/20111008020601/http://www.clonedinchina.com/2010/01/white-thinkpad-x100e-unboxed.html |archive-date=8 October 2011 |url-status=usurped |date= 6 January 2010 |work=Cloned in China }}</ref> Those were more like high-end netbooks, whereas the X200 series were more like full ultraportables, featuring Intel Core (previously Core 2 and Celeron) series CPUs rather than AMD netbook CPUs.

The X Series with "tablet" suffixes is an outdated variant of the 12" X Series models, with low voltage CPUs and a flip-screen tablet [[resistive touchscreen]]. These include the traditional ThinkPad features, and have been noted for using a higher quality AFFS-type screen with better viewing angles compared to the screens used on other ThinkPads.

===P series (2015–current)===
{{Main|ThinkPad P series}}
The P Series line of laptops replaced the W series and reintroduced 17.3" screens to the ThinkPad line. The P Series (excluding models with 's' suffix) is designed for engineers, architects, animators, etc. and comes with a variety of "high-end" options. All P series models come included with fingerprint readers. The P series includes features such as dedicated magnesium roll cages, more indicator LED lights, and high-resolution displays.

{{Main|IBM ThinkPad 240}}

The ultraportable ThinkPad [[IBM ThinkPad 240|240]] (X, Z) started with an Intel [[Celeron]] processor and went up to the 600&nbsp;MHz Intel [[Pentium III]]. In models using the [[Intel 440BX]] chipset, the RAM was expandable to 320&nbsp;MB max with a BIOS update. Models had a {{convert|10.4|in|mm|abbr=on}} screen and an {{convert|18|mm|in|abbr=on}} key pitch (a standard key pitch is {{convert|19|mm|in|abbr=on}}). They were also one of the first ThinkPad series to contain a built-in [[Mini PCI]] card slot (form factor 3b). The 240s have no optical disc drives and an external floppy drive. An optional extended battery sticks out the bottom like a bar and props up the back of the laptop. Weighing in at {{convert|2.9|lb|kg|abbr=on}}, these were the smallest and lightest ThinkPads ever made.

===500 series===
The 500 series <small>([[IBM ThinkPad 500|500]], 510, [[IBM ThinkPad 560|560 (E, X, Z)]], [[IBM ThinkPad 570|570 (E)]])</small> were the main line of the ultraportable ThinkPads. Starting with the 486SLC2-50 to the Pentium III 500, these machines had only a hard disk on board. Any other drives were external (or in the 570's case in the UltraBase). They weighed in at around {{convert|4|lb|kg|abbr=on}}.

The 500 series was succeeded by the X## series.

===600 series===
{{Main|IBM ThinkPad 600}}

The 600 series <small>(600, 600E, and 600X)</small> are thinner variants of the [[IBM ThinkPad 770|770]] series. The 600 series packed a {{convert|12.1|in|mm|abbr=on}} SVGA or a {{convert|13.3|in|mm|abbr=on}} XGA TFT LCD, Pentium MMX, Pentium II or III processor, full-sized keyboard, and optical bay into a package weighing roughly {{convert|5|lb|kg|abbr=on}}. IBM was able to create this light, fully featured machine by using lightweight but strong carbon fiber composite plastics. The battery shipped with some 600 series models had a manufacturing defect that left it vulnerable to [[memory effect]] and resulted in poor battery life, but this problem can be avoided by use of a third-party battery.

The 700 series was succeeded by the T## series.

===800 series===
{{Main|IBM ThinkPad 800 series}}

The ThinkPad 800 series <small>(800/820/821/822/823/850/851/860)</small> were unique as they were based on the [[PowerPC]] architecture rather than the Intel [[x86]] architecture. Most of the 800 Series laptops used the [[PowerPC 603e]] CPU, at speeds of 100&nbsp;MHz, or 166&nbsp;MHz in the 860 model. The PowerPC ThinkPad line was considerably more expensive than the standard x86 ThinkPads — even a modestly configured 850 cost upwards of $12,000.<ref>{{cite web |url=https://tecnopolis.ca/aixtp/tphistory.html |last=Cordes |first=Trevor E. |title=IBM PowerPC ThinkPad History |date=24 July 2008 |access-date=1 June 2014 |website=tecnopolis.ca |archive-date=31 December 2014 |archive-url=https://web.archive.org/web/20141231234028/https://tecnopolis.ca/aixtp/tphistory.html |url-status=live }}</ref> All of the PowerPC ThinkPads could run [[Windows NT 3.51]] and [[Windows NT 4.0|4.0]],<ref>{{cite web|url=https://www.youtube.com/watch?v=3bxJIA8hscI | archive-url=https://web.archive.org/web/20110915222148/http://www.youtube.com/watch?v=3bxJIA8hscI| archive-date=2011-09-15 | url-status=dead|title=Windows NT on PowerPC ThinkPad |via=YouTube |date=8 January 2010 |access-date=28 September 2013}}</ref> [[AIX operating system|AIX]] 4.1.x, and [[Solaris (operating system)|Solaris]] Desktop 2.5.1 PowerPC Edition.

===WorkPad===
Based on ThinkPad design although branded WorkPad, the IBM WorkPad z50 was a [[Handheld PC]] running [[Windows CE]], released in 1999.<ref>{{cite web|url=https://www.hpcfactor.com/reviews/hardware/ibm/workpad-z50/|title=IBM Workpad z50 Review|access-date=21 October 2020|archive-date=22 October 2020|archive-url=https://web.archive.org/web/20201022081044/https://www.hpcfactor.com/reviews/hardware/ibm/workpad-z50/|url-status=live |first=Chris |last=Tilley |date=3 March 2005}}</ref> The [[IBM WorkPad|WorkPad brand of products]], outside of the z50 model, was a line of [[personal digital assistant]]s(PDAs).

One notable ThinkPad in the i Series lineup are the '''S3x (S30/S31)''' models: featuring a unique keyboard and lid design allowing a standard size keyboard to fit in a chassis that otherwise wouldn't be able to support the protruding keyboard. These models were largely only available in Asia Pacific. IBM offered an optional piano black lid on these models (designed by the Yamato Design lab).<ref>{{cite web|url=http://thinkpadfc.blogspot.ca/2013/05/memory-thinkpad-iseries-s30-s31-do-you-still-keep-this-beast.html|title=[Memory] - ThinkPad iSeries S30/S31 - Do You Still Keep This Beast?  |website=ThinkPad FC |access-date=1 January 2015|archive-date=8 February 2016|archive-url=https://web.archive.org/web/20160208032933/http://thinkpadfc.blogspot.ca/2013/05/memory-thinkpad-iseries-s30-s31-do-you-still-keep-this-beast.html|url-status=dead}}</ref> This is the only ThinkPad since the 701C to feature a special design to accommodate a keyboard that's physically larger than the laptop and also the only ThinkPad (aside from the Z61) to deviate away from the standard matte lid.{{citation needed|date=October 2020}}

The A series was developed as an all-around productivity machine, equipped with hardware powerful enough to make it a desktop replacement. Hence it was the biggest and heaviest ThinkPad series of its time, but also had features not even found in a T series of the same age. The A series was dropped in favor of the R and G series.

The A31 was released in 2002 as a desktop replacement system equipped with: A Pentium 4-M processor clocked at 1.6, 1.8, 1.9, or 2.0&nbsp;GHz (max supported is a 2.6&nbsp;GHz), An ATI Mobility Radeon 7500, 128 or 256&nbsp;MB of PC2100 RAM (officially upgradable to 1&nbsp;GB but can be unofficially upgraded to 2&nbsp;GB), IBM High Rate Wireless (PRISM 2.5 Based, can be modified to support WPA-TKIP) and equipped with a 20, 30, or 40&nbsp;GB hard disk drive.

===R series (2001–2010, 2018-present?) {{anchor|R series}}===

{{Main|ThinkPad R series}}

The R series was a budget line, beginning with the R30 in 2001 and ending with the R400 and R500 presented in 2008.

[[File:IBM Thinkpads.jpg|thumb|An IBM ThinkPad R60 from 2006 (right) next to a T60 also from 2006]]

The successors also from 2006 of the R400 and R500 models are the [[ThinkPad L series|L series]] models L412 and L512.

A notable model is the R50p with an optional 15" {{resx|2048|1536}} IPS LCD screen (introduced in 2003).<ref>{{cite web|url=https://support.lenovo.com/us/en/solutions/pd010746|publisher=Lenovo|title=Detailed specifications – ThinkPad R50, R50p, R51|access-date=10 February 2019|archive-date=12 February 2019|archive-url=https://web.archive.org/web/20190212011607/https://support.lenovo.com/us/en/solutions/pd010746|url-status=dead}}</ref>

The R series reintroduced in 2018 (for Chinese market only) with the same hardware as [[ThinkPad E series|E series]] models, but with aluminum display cover, discrete GPU, TPM chip and fingerprint reader.

===G series (2003–2006) {{anchor|G series}}===
{{Main|ThinkPad G series}}

The G series consisted of only three models, the G40, G41 and G50 (which was only sold in Japan). Being large and heavy machines, equipped with powerful desktop processors, this line of ThinkPads consequently served mainly as budget replacements for desktop computers. 

The G series was able to be configured with either an entry-level Celeron or a 3&nbsp;GHz Pentium 4 processor. The G series line of ThinkPads often received criticism for its heft, weighing in at 8.4lbs (3.81kg). <ref>{{cite web |title=CNET Thinkpad G-Series Review |url=https://www.cnet.com/reviews/thinkpad-g-series-review/}}</ref>

===Z series (2005–2007) {{anchor|Z series}}===
The Z series was released as a high-end multimedia laptop; as a result this was the first ThinkPad to feature a widescreen (16:10 aspect ratio) display.<ref>{{cite web|url=http://www.tomsguide.com/us/widescreen-thinkpad-z60m,review-670.html|title=Is Lenovo's Widescreen Z60m the First Thinkpad Multimedia Powerhouse?|first=Harald |last=Thon |date=27 March 2006|work=Tom's Guide|access-date=30 April 2015|archive-date=25 November 2015|archive-url=https://web.archive.org/web/20151125132136/http://www.tomsguide.com/us/widescreen-thinkpad-z60m,review-670.html|url-status=dead}}</ref><ref>{{cite web|url=http://www.thinkwiki.org/wiki/TFT_display|title=TFT display|work=thinkwiki.org|access-date=30 April 2015|archive-date=28 April 2015|archive-url=https://web.archive.org/web/20150428074855/http://www.thinkwiki.org/wiki/TFT_display|url-status=live}}</ref> The Z series was also unique in that certain models featured an (optional) titanium lid.<ref>{{cite web|url=http://www.notebookreview.com/notebookreview/lenovo-thinkpad-z60t-review-pics-specs/|title=Lenovo ThinkPad Z60t Review (pics, specs)|work=NotebookReview.com|date=27 January 2022|access-date=30 April 2015|archive-date=2 May 2015|archive-url=https://web.archive.org/web/20150502192745/http://www.notebookreview.com/notebookreview/lenovo-thinkpad-z60t-review-pics-specs/|url-status=dead}}</ref> Integrated WWAN and a webcam were also found on some configurations. The series has only ever included the Z60 ([[ThinkPad Z60m|Z60m]] and Z60t) and Z61 (Z61m, Z61t and Z61p); the latter of which is the first Z series ThinkPad with Intel "[[Intel Core|Yonah]]" Dual-Core Technology. The processor supports [[Intel VT-x]]; this is disabled in the BIOS but can be turned on with a BIOS update. Running fully virtualised [[operating system]]s via [[Xen]] or [[VMware]] is therefore possible.<ref>{{cite web |last1=Hamm |first1=Steve |first2=Kenji |last2=Hall |url=http://www.businessweek.com/stories/2008-02-13/building-the-perfect-laptop |title=Building the Perfect Laptop |work=Bloomberg BusinessWeek |date=13 February 2008 |access-date=27 August 2014 |url-access=subscription |archive-date=14 September 2014 |archive-url=https://web.archive.org/web/20140914122346/http://www.businessweek.com/stories/2008-02-13/building-the-perfect-laptop |url-status=dead }}</ref> Despite the Z61 carrying the same number as the T61, the hardware of the Z61 is closer to a T60 (and likewise the Z60 being closer to a T43).

===ThinkPad Reserve Edition (2007)===
The "15-year anniversary" ThinkPad model (based on a X60s laptop). This model was initially known inside of Lenovo as the "Scout". This was the name of the horse ridden by [[Tonto]], the sidekick from the 1950s television series ''The Lone Ranger''. Lenovo envisioned the Scout as a very high-end ThinkPad that would be analogous to a luxury car. Each unit was covered in fine leather embossed with its owners initials. Extensive market research was conducted on how consumers would perceive this form factor. It was determined that they appreciated that it emphasised warmth, nature, and human relations over technology. The Scout was soon renamed the ThinkPad Reserve Edition. It came bundled with premium services including a dedicated 24-hour technical support hotline that would be answered immediately. It was released in 2007 and sold for $5,000 in the United States.<ref>{{cite news |last=Miller |first=Paul |url=https://www.engadget.com/2007/06/15/thinkpad-reserve-edition-unveiled/ |title=ThinkPad Reserve Edition unveiled |work=Engadget |date=15 June 2007 |access-date=7 May 2014 |archive-date=8 May 2014 |archive-url=https://web.archive.org/web/20140508030543/http://www.engadget.com/2007/06/15/thinkpad-reserve-edition-unveiled/ |url-status=live }}</ref><ref>{{cite web |last=Biggs |first=John |url=https://techcrunch.com/2007/09/05/thinkpad-reserve-edition/ |title=ThinkPad Reserve Edition |publisher=TechCrunch |date=5 September 2007 |access-date=7 May 2014 |archive-date=8 May 2014 |archive-url=https://web.archive.org/web/20140508031023/http://techcrunch.com/2007/09/05/thinkpad-reserve-edition/ |url-status=live }}</ref>

===SL series (2008–2010) {{anchor|SL series}}===
[[File:Portable Screening Devices (1295) (8225036586).jpg|thumb|ThinkPad SL400]]
The SL series was launched in 2008 as a low-end ThinkPad targeted mainly geared toward small businesses.<ref>{{cite web|title=ThinkPad SL Series |date=25 July 2008 |work=Inside the Box lenovo Blog |url=http://www.lenovoblogs.com/insidethebox/2008/07/thinkpad-sl-series/ |access-date=31 May 2011|url-status=dead |archive-url=https://web.archive.org/web/20110602034544/http://www.lenovoblogs.com/insidethebox/2008/07/thinkpad-sl-series/ |archive-date=2 June 2011}}</ref> These lacked several traditional ThinkPad features, such as the ThinkLight, magnesium alloy roll cage, UltraBay, and lid latch, and use a 6-row keyboard with a different layout than the traditional 7-row ThinkPad keyboard; also, SL series models have IdeaPad-based firmware. Models offered included 13.3" (SL300), 14" (SL400 and SL410) and 15.6" (SL500 and SL510).

===W series (2008–2015) {{anchor|W series}}===
[[File:Lenovo Thinkpad - Three different sizes.jpg|thumb|17.3" W700 compared to a 15.6" T500 and a compact 12.5" X200]]
{{Main|ThinkPad W series}}

The W series laptops were introduced by Lenovo as [[Mobile workstation|workstation-class laptops]] with their own letter designation, a descendant of prior [[ThinkPad T series]] models suffixed with 'p' (e.g. T61p), and are geared towards CAD users, photographers, power users, and others, who need a high-performance system for demanding tasks. The W series laptops were launched in 2008, at the same time as the Intel Centrino 2, marking an overhaul of Lenovo's product lineup. The first two W series laptops introduced were the W500 and the W700.

Previously available were the W7xx series (17" widescreen model), the W500 (15.4" 16:10 ratio model), the W510 (15.6" 16:9 ratio model), and W520 (15.6" 16:9 ratio model). The W700ds and the W701ds both had two displays: a 17" main LCD and a 10" slide-out secondary LCD. The W7xx series were also available with a Wacom digitizer built into the palm rest. These high-performance workstation models offered more high-end components, such as quad core CPUs and higher-end workstation graphics compared to the T series, and were the most powerful ThinkPad laptops available. Until the W540, they retained the ThinkLight, UltraBay, roll cage, and lid latch found on the T series. The W540 release marked the end of the lid latch, ThinkLight, and hot-swappable UltraBays found in earlier models.

The '''ThinkPad W series''' [[laptops]] from [[Lenovo]] are described by the manufacturer as being "mobile workstations", and suit that description by being physically on the larger side of the laptop spectrum, with screens ranging from 15" to 17" in size. Most W series laptops offer high-end quad-core [[Intel]] processors with an integrated GPU as well as an [[Nvidia Quadro]] discrete GPU, utilizing [[Nvidia Optimus]] to switch between the two GPUs as required. Notable exceptions are the W500, which has ATI FireGL integrated workstation-class graphics, and the W550s, which is an [[Ultrabook]]-specification laptop with only a dual-core processor. The W series laptops offer [[independent software vendor]] certifications from various vendors such as [[Adobe Systems]] and [[Autodesk]] for CAD and 3D modeling software.

The ThinkPad W series has been discontinued and replaced by the [[ThinkPad P series|P series]] mobile workstations.

===Edge series (2010)===
{{Main|ThinkPad E series}}

The Edge series was released early in 2010 as small business and consumer-end machines. The design was a radical departure compared to the traditional black boxy ThinkPad design, with glossy surfaces (optional matte finish on later models), rounded corners, and silver trim. They were also offered in red, a first for the traditionally black ThinkPads. Like the SL, this series was targeted towards small businesses and consumers, and lack the roll cage, UltraBay, lid latch, and ThinkLight of traditional ThinkPads (though the 2011 E220s and E420s had ThinkLights).<ref>{{cite web |title= Lenovo Announces Premium ThinkPad Edge E220s, E420s SMB Notebooks |author= Hobbes, John |date= 3 January 2011 |work= Thinkpads.com |url= http://www.thinkpads.com/2011/01/03/lenovo-announces-premium-thinkpad-edge-e220s-e420s-smb-notebooks/ |access-date= 3 June 2011 |archive-date= 17 July 2011 |archive-url= https://web.archive.org/web/20110717051214/http://www.thinkpads.com/2011/01/03/lenovo-announces-premium-thinkpad-edge-e220s-e420s-smb-notebooks/ |url-status= dead }}</ref> This also introduced an [[island-style keyboard]] with a significantly different layout.

Models included 13.3" (Edge 13), 14" (Edge 14), and 15.6" (Edge 15) sizes. An 11.6" (Edge 11) model was offered, but not available in the United States.<ref>{{cite news |title= Lenovo ThinkPad Edge 11 announced with Intel and AMD options, denied US citizenship |last= Stern |first=Joanna |date= 28 September 2010 |work= [[Engadget]] |url= https://www.engadget.com/2010/09/28/lenovo-thinkpad-edge-11-announced-with-intel-and-amd-options-de/ |access-date= 3 June 2011 |archive-date= 4 June 2011 |archive-url= https://web.archive.org/web/20110604172911/http://www.engadget.com/2010/09/28/lenovo-thinkpad-edge-11-announced-with-intel-and-amd-options-de/ |url-status= live }}</ref> The latest models of E series can be offered with Edge branding,<ref>{{cite web|url= http://gamertops.com/lenovo-thinkpad-edge-e545-review|title= Lenovo Thinkpad Edge E545 Review|publisher= Gaming Laptop|access-date= 23 February 2015|archive-date= 22 February 2015|archive-url= https://web.archive.org/web/20150222180449/http://gamertops.com/lenovo-thinkpad-edge-e545-review|url-status= dead}}</ref> but this naming is optional and uncommon.

==== ThinkPad Twist (2012) ====
The [[ThinkPad Twist]] (Edge S230u) is a laptop/tablet computer hybrid aimed at high-end users. The Twist gets its name from its screen's ability to twist in a manner that converts the device into a tablet. The Twist has a 12.5" screen and makes use of Intel's Core i7 processor and SSD technology in lieu of a hard drive.<ref name="Twist">{{cite web|url=http://www.techradar.com/reviews/pc-mac/laptops-portable-pcs/lenovo-thinkpad-twist-1107355/review|title=Lenovo ThinkPad Twist review|first=James |last=Stables |work=TechRadar|date=21 January 2013|access-date=27 November 2012|archive-date=29 November 2012|archive-url=https://web.archive.org/web/20121129114114/http://www.techradar.com/reviews/pc-mac/laptops-portable-pcs/lenovo-thinkpad-twist-1107355/review|url-status=live}}</ref>

In a review for ''Engadget'' Dana Wollman wrote, "Lately, we feel like all of our reviews of Windows 8 convertibles end the same way. The ThinkPad Twist has plenty going for it: a bright IPS display, a good port selection, an affordable price and an unrivaled typing experience. Like ThinkPads past, it also offers some useful software features for businesses lacking dedicated IT departments. All good things, but what's a road warrior to do when the battery barely lasts four hours? Something tells us the Twist will still appeal to Lenovo loyalists, folks who trust ThinkPad's build quality and wouldn't be caught dead using any other keyboard. If you're more brand-agnostic, though, there are other Windows 8 convertibles with comfortable keyboards – not to mention, sharper screens, faster performance and longer battery life."<ref name="Engadget">{{cite web|url=https://www.engadget.com/2012/11/21/lenovo-thinkpad-twist-review/|title=Lenovo ThinkPad Twist review: an old form factor gets new life with Windows 8|work=Engadget|publisher=AOL|access-date=16 September 2017|archive-date=15 August 2017|archive-url=https://web.archive.org/web/20170815221721/https://www.engadget.com/2012/11/21/lenovo-thinkpad-twist-review/|url-status=live |first=Dana |last=Wollman |date=21 November 2012}}</ref>

===ThinkPad Helix (2013–2015)===
{{Main|ThinkPad Helix}}

[[File:ThinkPad Helix.jpeg|thumb|The ThinkPad Helix on display in Hong Kong]]
The Helix is a [[convertible laptop]] satisfying both tablet and conventional notebook users. It uses a "rip and flip" design that allows the user to detach the display and then replace it facing in a different direction. It sports an 11.6" Full HD (1920 × 1080) display, with support for Windows 8 multi-touch. As all essential processing hardware is contained in the display assembly and it has multitouch capability, the detached monitor can be used as a standalone tablet computer. The Helix's high-end hardware and build quality, including [[Gorilla Glass]], stylus-based input, and Intel vPro hardware-based security features, are designed to appeal to business users.<ref name="Helix1">{{cite web|url=http://www.digitaltrends.com/mobile/lenovo-shows-thinkpad-helix-and-ideapad-yoga-11s-convertibles/|title=Lenovo announces ThinkPad Helix and IdeaPad Yoga 11S convertibles|first=Matthew |last=Smith |date=7 January 2013|work=Digital Trends|access-date=8 January 2013|archive-date=11 January 2013|archive-url=https://web.archive.org/web/20130111112555/http://www.digitaltrends.com/mobile/lenovo-shows-thinkpad-helix-and-ideapad-yoga-11s-convertibles/|url-status=live}}</ref>

In a review published in ''Forbes'' Jason Evangelho wrote, "The first laptop I owned was a [[IBM ThinkPad T20 series|ThinkPad T20]], and the next one may very likely be the ThinkPad Helix which Lenovo unveiled at CES 2013. In a sea of touch-inspired Windows 8 hardware, it's the first ultrabook convertible with a form factor that gets everything right. The first batch of Windows 8 ultrabooks get high marks for their inspired designs, but aren't quite flexible enough to truly be BYOD (Bring Your Own Device) solutions. Lenovo's own IdeaPad Yoga came close, but the sensation of feeling the keyboard underneath your fingers when transformed into tablet mode was slightly jarring. Dell's XPS 12 solved that problem with its clever rotating hinge design, but I wanted the ability to remove the tablet display entirely from both of those products."<ref name="Forbes1">{{cite web|url=https://www.forbes.com/sites/jasonevangelho/2013/01/12/best-of-ces-is-lenovos-thinkpad-helix-the-perfect-ultrabooktablet-hybrid|title=Best of CES: Is Lenovo's ThinkPad Helix The Perfect Ultrabook/Tablet Hybrid?|first=Jason |last=Evangelho |date=12 January 2013 |work=Forbes|access-date=16 September 2017|archive-date=8 January 2019|archive-url=https://web.archive.org/web/20190108050102/https://www.forbes.com/sites/jasonevangelho/2013/01/12/best-of-ces-is-lenovos-thinkpad-helix-the-perfect-ultrabooktablet-hybrid|url-status=live}}</ref>

=== Docking stations (1993–current) ===
[[File:ThinkPad Ultra docking station.JPG|thumb|Ultra Docking Station for the T470, T460, T450, L440, L540, X240, T540, T440, T440, and W540 laptops]]
[[File:Thinkpad_docking_station_near_T61_laptop.JPG|thumb|Docking station for the T60, T61 and T400/T500 laptops]]The ThinkPad laptop line has a history of using docking stations to enhance functionality and connectivity. These stations provide additional ports, peripherals, and larger displays, transforming the laptop into a desktop-like setup. There are three types of ThinkPad docking stations: Port Replicators, which replicate the ports found on the laptop, Advanced Docking Stations, which offer more extensive functionality, built-in speakers, microphones, and card readers, and Desktop Docking Stations, which transform the ThinkPad into a desktop setup with a larger monitor, keyboard, and mouse.
