Wiki: ThinkPad
ThinkPad is the brand name for a range of portable laptop and notebook computers originally designed and sold by IBM. Since early 2005 the ThinkPad range has been manufactured and marketed by Lenovo, which purchased the IBM PC division. IBM ThinkPads have a reputation for generally being solidly built, dependable, and innovative.



ThinkPad R: Business notebook for standard business requirements, two internal bays, one of which is swappable. Models with an appended 'e' (economy) further cut-down versions. The R30/R31/R40e models were manufactured under license by Lenovo.
ThinkPad S: Subnotebook, extremely small and light, produced for Japanese market only.
ThinkPad T: Thin and light notebook aimed at the corporate market. Two internal drives, one of which is swappable.
ThinkPad X: Subnotebook, very small and light, hard drive internal, no internal optical drive, 12" screen. A tablet version (X41 and X60 Tablets) [2] was introduced in June of 2005, and again in December of 2006. The latest update, the X61 Tablet, was released May 31, 2007.



Model-specific information


ThinkPad T20 series (T20, T21, T22, T23) (IBM THINKPAD T20 Battery Li-ion, 10.80 (Compatible with 11.10V), 4000mAh)

Mobile Pentium III or Mobile Pentium III-M, sub-5 lb (2.3 kg) class machines. Contained processors ranging from 0.18 micrometre Mobile Pentium III 650 MHz to 0.13 micrometre Mobile Pentium III-M 1.20 GHz. Typically had 14.1 inch XGA screens, Ultrabay 2000 optical drives, S3 Savage/IX-MV graphics chip and Cirrus Logic CS 4614/22/24 sound chips; although variations along the line existed. Introduced the ThinkLight, a LED mounted inside the upper screen lip that illuminates the keyboard (activated with Fn-PgUp, the extreme diagonal keys); and titanium-reinforced and rubberized screen lids. Used MiniPCI form factor cards, which could be modem and/or ethernet. With the T23, an internal WiFi antenna became available, so WiFi miniPCI cards could be used. These models did not contain the active hard drive protection or touchpad pointing device which appeared in later models. They were clad in black non-slip rubber with embedded glitter. The case lid had tabs along the edge that interlocked with depressions in the lower case when closed, to reduce case flexing. Comparatively more stylish, functional, and rugged machines; and easy to disassemble for repair or upgrades.

ThinkPad T30 series
Solely includes the T30 model. Features include an Intel Mobile Pentium 4 processor ranging from 1.6 GHz to 2.4 GHz. Any T30 model may accommodate up to a 2.4 GHz processor with the latest BIOS and Embedded Controller upgrades. Graphics are provided by ATI Radeon Mobility 7500 hardware with 16 MB of discrete video memory, which supports external widescreen resolutions. Users have even reported success with output resolutions of 1920x1200 via DVI on the optional Port Replicator II docking station, although IBM claims a limit of 1280x1024 due to a weak TMDS transmitter. The T30 was available with a 14.1 inch screen, with resolutions of 1024 x 768 and 1400 x 1050. DVI video output is available with the optional Port Replicator II docking station, but resolution is officially limited to 1280x1024.[3] Features available include the embedded security subsystem, UltraNav touchpad, 256 MB standard memory (1 GB maximum according to IBM manual, but it has been reported [4] to accept 2 GB of RAM)[5], a 20, 40 or 60 GB hard disk, Ultrabay Plus drive, wireless, and Bluetooth. The T30 also contains a miniPCI slot usable for a wireless card. The shell is titanium-reinforced composite. The whole package was a bit heavier and thicker than the T4x series.



ThinkPad T40 series (battery item:compatible with IBM THINKPAD R50 SERIES battery)

Includes the T40(USA sponsor:IBm thinkpad r50 battery), T41(UK sponsor:IBm thinkpad r50 battery), T42(USA sponsor:IBm thinkpad r50 battery), T43, and associated "p" series (for "performance"; e.g., T43p). A typical 14.1 inch T4x weighs 2.2 kg (4.9 lb), slightly less than the 600 series, and features an Intel Pentium M Processor (ranging from the Intel Pentium M at 1.3 GHz to the Intel Pentium M 770 at 2.13 GHz), a 14.1 or 15 inch LCD (XGA, SXGA+), an integrated GPU (Intel Graphics Media Adapter 900) or a discrete GPU (Radeon x300, 7500, 9000, Fire GL 9000, 9600, Fire GL T2, X300, and Fire GL V3200), and a hard drive ranging in size from 30 to 100 GB with the Active Protection System to protect the hard drive (T41 and later models). "p" (mobile workstation) models are also available with a 14 inch SXGA+ or a 15 inch SXGA+/UXGA FlexView display with wide viewing angle and high density IPS technology. These 15-inch display models weigh slightly more than their lesser brethren, with optical drive and battery, at 2.7 kg (5.9 lb). All T4x models use either 6-cell or 9-cell lithium-ion batteries, as well as an optional 4-cell Ultrabay Slim lithium-polymer battery. Some T42 and T43 models feature a biometric security system with built-in fingerprint reader. Some types of the model also had the option to include Bluetooth support. The T40 was IBM's first ThinkPad to use the Pentium M "Banias" CPU. The T42 employed a Pentium M "Dothan" processor with a 400 MHz frontside bus, while the T43 used a later revision Dothan running a 533 MHz FSB.
