ThinkPad is the brand name for a highly successful 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. The ThinkPad range was introduced at Comdex 1992 using the series designators 300, 500 and 700 , the 300 series being the "budget", the 500 series "midrange" and the 700 series "high end". This designation continued until the year 2000 when IBM introduced the "T" series as 600/700 series replacements, and the 3,5 and 7 series model designations were phased out for A & X series. The A series was later partially replaced by the R series. Traditionally black, ThinkPads feature innovations such as the magnesium or titanium composite, TrackPoint pointing device that allows the performance near that of a mouse, ThinkLight, an LED keyboard light put on the top of the LCD screen, solidly constructed full size keyboard , the Active Protection System, a device that detects when a ThinkPad is falling and shuts the hard drive down to prevent damage, biometric fingerprint reader, dual wireless antennae that allow for more stable connections, and the Client Security Solution that allows for industry standard TPM encryption and password management to counter keylogger spywares. ThinkPads have a reputation for generally being solidly built, dependable, and innovative. Design history Tom Hardy, corporate manager of the IBM Design Program met with Italian-based designer Richard Sapper and Kazuhiko Yamazaki, lead notebook designer at IBM's Yamato Design Center in Japan. Sapper proposed a design inspired by the Shokado bento, a traditional black-lacquered Japanese lunch box. IBM launched the ThinkPad line in 1992 with the ThinkPad 700 and 700C . The original ThinkPad was a tablet computer, without a keyboard. It featured a monochrome LCD screen, 40 MB flash memory , with PenPoint OS from Go, and handwriting recognizer from IBM. The keyboard version with Microsoft Windows 3.1 was next and sold for US$4,350, weighed 3 kg , and had dimensions of 2.2 by 11.7 by 8.3 inches . It featured a 10.4 inch LCD , a 25 MHz 486SLC processor, a 120 MB hard disk drive, and an easy-to-use keyboard featuring the TrackPoint pointing device. The bright red TrackPoint, embedded in the keyboard, enabled the notebook to be used on an airline tray table without a mouse. Although the tablet version was not commercially successful, the ThinkPad Tablet and Apple Newton were the beginning of PDAs and mobile computing. The ThinkPad name was inspired by the leather-bound pocket notebooks issued to all IBM employees with the corporate motto 'Think' embossed on the cover. IBM's corporate naming team was initially against using the ThinkPad name since all previous IBM computers were referred to by model numbers rather than names. However, the popularity of the ThinkPad brand with the press convinced IBM to retain the name. ThinkPad model types The following is a list of various recent families of ThinkPad models. - ThinkPad A: All-in-one notebook, heavy, large, three drive bays total of which two are swappable bays. Discontinued in 2004. Some of the "p" models were the first ThinkPads available with a 15 inch UXGA "FlexView" display, most remarkable is A31p, marketed as first mobile workstation. There are now 'desktop replacement' configurations to replace the A series.
- ThinkPad G: Desktop replacement machines built around desktop processors, large and heavy with limited battery runtime. Discontinued in 2005.
- ThinkPad i Series: Budget consumer series notebooks manufactured by Acer under license from IBM. Discontinued. The i Series were the first ThinkPad models to include the 'Windows' and 'Menu' keys promoted by Microsoft and common on other vendors' laptops since the mid-nineties.
- ThinkPad R: Consumer notebook with two internal bays, one of which is swappable. Models with an appended 'e' 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 was introduced in June of 2005.
- ThinkPad Z: The first ThinkPad intended for entertainment with wide-screen display, also the first ThinkPad that was introduced by Lenovo after the acquisition of IBM's facilities. Production started in 2005. The Z series are the first ThinkPad models since the i Series that include the 'Windows' and 'Menu' keys.
Model specific information - ThinkPad 235
- Type 2607, or the Japan-only ThinkPad 235, is an interesting product because it is a progeny of the IBM/Ricoh RIOS project. Also known as Clavius or Chandra2, it contains unusual features like the presence of 3 PCMCIA slots and the use of dual Camcorder batteries as a source of power. Features an Intel Pentium MMX 233 MHz CPU, support for up to 160 MB of EDO memory, and a built-in 2.5 inch hard drive with UDMA support. Hitachi markets Chandra2 as the Prius Note 210.
- ThinkPad 300 series
- The 300 series was a long running value series starting at the 386SL/25 all the way to the Pentium III 450. They were a bit large and slower than the more full featured models but offered a less expensive ThinkPad.
- ThinkPad 500 series
- The 500 series were the main line of the ultraportable ThinkPads. Starting with the 486SX2-50 Blue Lightning to the Pentium III 500, these machines had only a hard disk onboard. Any other drives were external . They weighed in at around 4 pounds and because of their excellent design are still in use today.
- ThinkPad 600 series
- The 600 series are the direct predecessors of the T series, and are legendary for their portability and sturdy construction. The 600 series packed a 12.1" SVGA or a 13.3" XGA TFT LCD, Pentium MMX, Pentium II or III processor, full sized keyboard, and optical bay into a package weighing roughly 2.3 kg . IBM was able to create this light, fully featured machine by using lightweight but strong carbon fibre composite plastics.
- ThinkPad 700 series
- The 700 series were the cutting edge Intel-based ThinkPads. They featured the best screens, largest hard drives and fastest processors available at the time. This was the first successful ThinkPad introduced in 1992 .
- ThinkPad 800 series
- The PowerPC ThinkPad series, were unique in that they ran on the PowerPC architecture, and not the x86 architecture. They all used the PowerPC 603e CPU, at speeds of 100 MHz, or 166 MHz in the 860 model. The 800 may have used a 603, and it is unclear if the 800 was experimental or not. All units used SCSI 2 instead of IDE. The units are believed to have all been extremely expensive, as the 850 cost upwards of $12,000 USD. The 800 series can run Windows NT 3.5 , OS/2, AIX 4.14, Solaris

Introduced the ThinkLight, a LED mounted inside the upper screen lip and illuminating the keyboard ; and titanium-reinforced screen lids. Used MiniPCI form factor cards, which could be modem and/or ethernet. With the T23, an internal wi-fi antenna became available, so wi-fi miniPCI cards could be used. Did not contain the active hard drive protection or touchpad pointing device which appeared in later models. T series ThinkPads 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.

Lenovo UltraBay UltraBay is Lenovo's name for the swappable drive slot. Introduced on the 750 series ThinkPads, this technology has gone through redesigns with almost every new generation of ThinkPad, leading to some confusion. The following table gives an overview of the different UltraBay types, in which models they occurred and what drives are available for them. Note that the optical drive bay in G series ThinkPads is not an UltraBay in that the drives are fixed and not removable. On the media side different UltraBays relate to the form factor of the drives they accept; for example, early A, T and X series models can accept UltraBay devices up to 12.5 mm thick, whereas current T and X series machines are limited to devices no more than 9.5 mm thick.
