ThinkPad A series

The ThinkPad A series was released as part of IBM's initiative in 2000 to revamp and streamline their lineup of computers. Following decreasing sales in their PC division, a decline that started from following a high of $1 billion in 1998{{cite web |title=IBM hangs hopes on new ThinkPad laptops |url=https://www.cnet.com/tech/tech-industry/ibm-hangs-hopes-on-new-thinkpad-laptops/ |website=CNET |access-date=23 April 2025}} and lead to $550 million in lost revenues starting the first quarter of 2000,{{cite web |title=IBM revamps notebook lineup |url=https://www.cnet.com/culture/ibm-revamps-notebook-lineup/ |website=CNET |access-date=25 January 2025}} IBM invested more into the ThinkPad line, leading to increased sales in the corporate market. The ThinkPad A series with the A20m and A20p were released to acclaim alongside the ThinkPad T series as its powerful, larger sibling. Being described as "a stellar choice for small or large businesses" that "trades portability for power"{{cite web |last1=Jacobi |first1=Jon |title=ThinkPad A series review: ThinkPad A series |url=https://www.cnet.com/reviews/thinkpad-a-series-review/ |website=cnet.com |access-date=25 January 2025}} by CNET in 2002 while reviewing the A3x series. It offered little compromise when compared to the T series both in the case construction, boasting titanium composite lids,{{efn|name = only models with suffix -p|This was only present in Axxp models}} and in the keyboard, offering sturdy and responsive keyboards with 2.7mm of travel, being rated as "a cut above anything you'll find elsewhere, except on some Dell notebooks" by CNET in the same review. The A20m was also one of the first laptops to offer a Intel Celerons in a 15" form factor, leading to 15" displays being more accessible than before.

IBM's revamps were focused on improving wireless connectivity and user experience. Their wireless connectivity improvements lead to the addition of optional wireless LAN that connected to the mPCI slot and Bluetooth{{cite web |last1=Brewin |first1=Bob |title=IBM introduces titanium-clad ThinkPads |url=https://www.computerworld.com/article/1369961/ibm-introduces-titanium-clad-thinkpads.html |website=Computer World |access-date=25 January 2025}} that connected through the UltraPort, a modified USB port that could expand a ThinkPad's functions by adding features such as a CompactFlash slot or a webcam. To give users things to do on the internet, IBM hosted online demonstrations, tips, and forums to provide user help and share experiences. To improve user experience, IBM added the ThinkLight, dedicated volume buttons, and ThinkPad button(later the ThinkVantage button).{{cite web |last1=Lewis |first1=Peter |title=STATE OF THE ART; New ThinkPads: Laptop as S.U.V. |url=https://www.nytimes.com/2000/05/25/technology/state-of-the-art-new-thinkpads-laptop-as-suv.html |website=New York Times |access-date=25 January 2025}}

To streamline the ThinkPad lineup, IBM replaced their previous ambiguous 300, 500, 600, and 700 series lineups with the better defined A, T, and X series, while keeping their i series around as their ultra-budget line. Naming wise, their streamlining involved the shift from a three number scheme to a system with a letter followed by two numbers. Whereas the previous naming system had a number in front to denote the series a product belonged to followed by a number indicating generation and a third number distinguishing revisions, the new scheme changed the first number into a letter that served the same function. Just like the previous naming scheme, letter suffixes can be added to the end of the model number to signify types of the model it is attached to.

The A series wasn't simply a larger version of the T series either. As a desktop replacement, the A series offered many additional features not available on the T series such as a third line-in audio jack, 4-pin FireWire, floppy drive,{{efn|name=for A2x series|Only for A2xm and A2xp models, not for A2xe}} and more powerful GPU options. It also had both larger and high resolution IPS screens, a second UltraBay, and web navigation keys on the left of the keyboard,{{cite web |title=Web Navigation Keys |url=https://www.thinkwiki.org/wiki/Web_Navigation_Keys |website=thinkwiki.org |access-date=25 January 2025}} features that no other ThinkPad at the time had. While the web navigation keys were never present on any other ThinkPad released, those high resolution IPS screens, with drastically greater viewing angles and marketed as "Flexview", were added as an option for future ThinkPads of other models. Which lead to ThinkPads of this time being known for their great displays.

The ThinkPad A20m was released in 2000 as a successor to the ThinkPad 770. It was released alongside the A20p and was meant to be both the lower cost and mainstream option of the A series. A carbon fiber case similar to the one in the ThinkPad 240 and 600 series was used to maintain stiffness while keeping the laptop somewhat light.

It came in two body types with 3 display sizes. The 14" body type could be fitted with either a 12.1" SVGA(800x600) or a 14.1" XGA(1024x768) display. The 15" body type could only be optioned with a 15" XGA(1024x768) display.

The ThinkPad A20p was released as the high end version of the A20m. It sported a titanium lid similar to the T20 released around the same time, a higher capacity battery, an UltraPort, higher resolution displays, and more performant CPUs and GPUs when compared to the A20m.

The A20p was only available in the 15" body type with a 15" SXGA+(1400x1050) display.

The ThinkPad A21e was released starting at $1499 and was aimed at "budget-conscious business users".{{cite web |last1=Zipern |first1=Andrew |title=NEWS WATCH; More Storage in Your Pocket For the Computer on Your Lap |url=https://www.nytimes.com/2001/02/08/technology/news-watch-more-storage-in-your-pocket-for-the-computer-on-your-lap.html |website=New York Times |access-date=27 January 2025}}

It had features cut out, including the ability to dock to the full sized ThinkPad Dock,{{cite web |title=Thinkpad Dock |url=https://www.thinkwiki.org/wiki/ThinkPad_Dock |website=ThinkWiki |access-date=27 January 2025}} was made of ABS plastic, had a lower end 440MX chipset that couldn't handle as much RAM, did not have battery terminals nor the ability to hot or warm swap in the UltraBay, and couldn't support more than one PCMCIA card at a time.

During the A21e's lifetime, two types of it were released. One, released in October 2000, was based on the A21m. In Japan only, there were versions of this type of A21e made called the ThinkPad i Series 1800.{{cite web |title=ThinkPad i 1800 2628-ITJ 2628-ITJ |url=https://www.inversenet.co.jp/pclist/product/IBM-note/2628%252DITJ.html |website=Inversenet |access-date=27 January 2025}}{{cite web |title=ThinkPad A21e 2632-I1J |url=https://tp.krelay.de/index.php?type=2632 |website=tp.krelay |access-date=27 January 2025}}{{cite web |title=ThinkPad i 1800 2632-I1J 2632-I1J |url=https://www.inversenet.co.jp/pclist/product/IBM-note/2632%252DI1J.html |website=Inversenet |access-date=27 January 2025}}

The other was a smaller model released in March 2001 and didn't have a 1.44MB floppy drive or upgradeable CPUs. This was the model that the A22e would revise on. The i series 1800 would also be updated to be based on this newer model of the A21e.{{cite web |title=ThinkPad i 1800 2655-P3J 2655-P3J |url=https://www.inversenet.co.jp/pclist/product/IBM-note/2655%252DP3J.html |website=Inversenet |access-date=27 January 2025}}

The A21m based model was available in two both 14" and 15" body types. The 14" body type housed either a 12.1" SVGA(800x600) or a 14.1"{{efn|name = Only for i Series 1800|Only the i series 1800 based on this model was available in 14.1"}} XGA(1024x768) display. The 15" body type was only available with a 15" XGA(1024x768) display.

The newer, smaller model was only offered in the 14" body type which could be optioned with 12.1", 13.3",{{cite web |title=Thinkpad A21e 2655-33U |url=https://tp.krelay.de/index.php?type=2655-33u |website=tp.krelay |access-date=27 January 2025}} or 14.1" displays. the 12" display was SVGA(800x600) while the 13" and 14" displays were XGA(1024x768).

The ThinkPad A21m was released in September of 2000 as a revision of the A20m with faster CPUs.

It came in two body types with 3 display sizes. The 14" body type could be fitted with either a 12.1" SVGA(800x600) or a 14.1" XGA(1024x768) display. The 15" body type could only be optioned with a 15" XGA(1024x768) display.

The ThinkPad A21p was released as a revision of the A20p with faster CPUs and higher resolution displays. PCWorld gave the A21p a score of 89,{{cite web |last1=Thornton |first1=Carla |title=Top 15 notebook PCs |url=https://www.proquest.com/docview/231440135/6129F3C83F764077PQ/4?accountid=193322&sourcetype=Magazines |website=Proquest-PCWorld |access-date=27 January 2025}} rating it the best "Power Notebook" due to its chart topping performance. In the main review of the laptop, they noted its high resolution screen and high-speed mobile Pentium III processor, calling it the "Lexus of portables".{{cite web |last1=Thornton |first1=Carla |title=IBM ThinkPad A21p |url=https://www.proquest.com/docview/200750975?sourcetype=Trade%20Journals |website=ProQuest-PCWorld |access-date=27 January 2025}}

The A21p was only available in the 15" body type with a 15" UXGA(1600x1200) display.

The ThinkPad A22e was released in June 2001 and was a revision on the newer version of the A21e. A new version of i series 1800 was released based on the A22e as well.{{cite web|url=https://www-01.ibm.com/common/ssi/ShowDoc.wss?docURL=%2Fcommon%2Fssi%2Frep_ca%2F0%2F760%2FMBL01190%2Findex.html&lang=en&request_locale=ja|title=ThinkPad i Series 1800(2655-PAJ)の発表|date=2008-11-19|publisher=ibm.com|language=ja|access-date=2018-11-26|archive-date=27 November 2018|archive-url=https://web.archive.org/web/20181127110213/https://www-01.ibm.com/common/ssi/ShowDoc.wss?docURL=%2Fcommon%2Fssi%2Frep_ca%2F0%2F760%2FMBL01190%2Findex.html&lang=en&request_locale=ja|url-status=live}} This would be the last A series with an -e suffix as the ThinkPad R series succeeded it in the space of low cost smaller laptops.

The A22e was only offered in the 14" body type which could either house a 13.3" or a 14.1"{{cite web |title=ThinkPad A22e 2655-PS1 |url=https://tp.krelay.de/index.php?type=2655-PS1 |website=tp.krelay |access-date=27 January 2025}} XGA(1024x768) display.

The ThinkPad A22m was released as a revision of the A21m with faster CPUs. While other A series models supported wireless LAN, it was the first A series model to have the option of wireless LAN connectivity from the factory. It was given the Editor's Choice Award from ZDNet in 2001 and was the best rated out of the 7 other "AV notebooks" reviewed, being fast with excellent build quality.{{cite web |title=ThinkPad A22m |url=https://www.zdnet.com/article/multimedia-notebooks/ |website=ZDNet |access-date=27 January 2025}} Starting with the A3x series, the smaller 14" body type from the mainstream Axxm linup of desktop replacements would be succeeded by the R series.

It came in two body types with 3 display sizes. The 14" body type could be fitted with either a 12.1" SVGA(800x600) or a 14.1" XGA(1024x768) display. The 15" body type could only be optioned with a 15" XGA(1024x768) display.

The ThinkPad A22p was released as a revision of the A21p with faster CPUs. In a review in 2001, Bloomberg called it the Lexus among portables due to it "[teaming] great design with top-shelf components, as well as a screen resolution of 1600 by 1200, the highest available for notebooks".{{cite web |title=IBM ThinkPad A22P |url=https://www.bloomberg.com./news/articles/2001-10-11/ibm-thinkpad-a22p |website=Bloomberg |access-date=27 January 2025}}

The A22p was only available in the 15" body type with a 15" UXGA(1600x1200) display.

The ThinkPad A30 was released in October 2001 alongside the ThinkPad R Series, the laptop line that replaced the lower cost lines of the A series. This was reflected in the positioning of the A series in IBM's lineup shifting from "Desktop alternatives covering a rage of performance and functionalities" to "High-performance desktop alternatives with exceptional versatility".

It, along with the ThinkPad R30 released at the same time, started the era of ThinkPad design of a cut corner on the left side back side with thin, exposed metal hinges, along with the introduction of page left and right keys which, along with the function row keys were colored in grey. This design was later brought to the T30 and the X3x series in 2002. While the cut corner and the grey color accents would only last in ThinkPad design until 2003 and 2005 respectively, the exposed metal hinges along with the blue enter key and the page left/right keys would stay with ThinkPads for much longer. The changes to the A series were not all positive though. In place of the carbon fiber construction of the Axxm series, ABS plastic lids and glass fiber reinforced plastic bottoms were used instead on the A30.

Being a desktop replacement, the laptop featured not just one but two UltraBays, One Ultrabay 2000 on the left side and another Ultrabay Plus on the right. The Ultrabay Plus{{efn|name=NoUltraBatt}} could be used for floppy, SuperDisk, ZIP, CD, or DVD drives just like an Ultrabay 2000, or for expanding other device functions such as adding a numpad or a cradle for the IBM WorkPad PDA. Not only were there two UltraBays, there were two Communication Daughter Card slots that could house either 56K modem cards or 10/100 Ethernet cards. It also included six web navigation keys on the left side of the keyboard, three of which were preprogramed while the other three were user programmable.

The A30 was available with 3 display options: a 14.1" XGA(1024x768), a 15.0" XGA(1024x768), or a 15.0" SXGA+(1400x1050), all of which were TN displays.

The ThinkPad A30p was the performance version of the A30, released at the same time. Based on the same chassis, the differences are mostly internal, with the only exterior differences being the inclusion of the UltraPort. However, the differences internally are drastic, not only is the unit more secure with the IBM Embedded Security Subsystem and more powerful in both processing power and graphics performance, it also features a high resolution, UXGA(1600x1200), IPS display—one of the first on a laptop.

The A30p came only with a UXGA(1600x1200) 15.0" IPS display.

The ThinkPad A31 was a revision to the ThinkPad A30 with mobile Pentium 4-M processors, DDR RAM, and faster ATI Mobility Radeon 7500 graphics. It was described as having a "knockout feature set" and being a "good choice for users who want a bit of portability without breaking the bank" by PCMag in a 2002 review.{{cite web |title=IBM ThinkPad A31 |url=https://www.pcmag.com/archive/ibm-thinkpad-a31-33267 |website=PCMag |access-date=30 January 2025}}

The A31 was available with 3 display options: a 14.1" XGA(1024x768), a 15.0" XGA(1024x768), or a 15.0" SXGA+(1400x1050), all of which were TN displays.

The ThinkPad A31p was a revision on the A30p and the performance version of the A31. Described as not just a desktop replacement but a workstation replacement{{cite web |title=IBM ThinkPad A31p |url=https://www.pcmag.com/archive/ibm-thinkpad-a31p-27565 |website=PCMag |access-date=30 January 2025}} by PCMag in 2002, It was updated with the ATI Mobility FireGL 7800, Pentium 4-M processors, and DDR RAM. Continuing to use IPS display technology, the A31p's screen was described to "remain crisp even to viewers sitting at extreme angles."{{cite web |title=IBM Thinkpad A31p |url=https://www.pcmag.com/archive/ibm-thinkpad-a31p-31372 |website=PCMag |access-date=31 January 2025}}

The ThinkPad A31p was the successor to the 760XD in the International Space Station. They were sent to the ISS starting in 2003 and stayed in use for six years until 2009 when the ThinkPad T61p replaced it.{{cite web |title=Photos: From the IBM ThinkPad to the Apple iPad – the tech used on the ISS |url=https://www.techrepublic.com/pictures/photos-from-the-thinkpad-to-the-ipad-the-tech-used-on-the-iss/?slide-index=4 |website=TechRepublic |access-date=31 January 2025}}

The A31p came only with a UXGA(1600x1200) 15.0" IPS display.
