ThinkPad is a brand of portable laptop and notebook personal computers originally designed, manufactured and sold by IBM. Since early 2005, the ThinkPad range has been manufactured and marketed by Lenovo, which purchased the IBM PC division.

History

IBM introduced the first three ThinkPad models, the 700, 700C, 700T, in October 1992. The 700C used the Microsoft Windows 3.1 operating system, 25 MHz 486SLC processor, 120 MB hard disk drive, the industry's first 10.4" TFT color display, 2.2" x 11.7" x 8.3" dimension (56 x 297 x 210 mm), and 3 kg (6.5 lb) weight, cost US$ 4,350. The design of the commercial versions differed significantly from the prototype's keyboard-less tablet design. The bright red TrackPoint, embedded in the keyboard, enabled the notebook to be used on an airline tray table without a mouse. An IBM researcher conceived the title "ThinkPad" from a corporate-issued leather-bound pocket notebook with the corporate motto 'Think' embossed on the cover. The name met disagreements from the IBM corporate naming committee because the nomenclature system for the IBM computers was then numerical; however, the brand name "ThinkPad" was kept as the press showed appreciation for the title.ThinkPads.com documents on ThinkPads The first ThinkPads were very successful, and soon collected more than 300 awards for design and quality.

The ThinkPad 750 flew aboard the Space Shuttle Endeavour during a mission to repair the Hubble Space Telescope on December 2, 1993. The ThinkPad 750C's task was to run a NASA test program which determined if radiation inherent in the space environment causes memory anomalies in the 750C or generates other unexpected problems. In 1995, the average number used was five, and in 1999 the average number was nine. Throughout 2006, a ThinkPad A31p was being used in the Service Module Central Post of the International Space Station and seven ThinkPad A31p laptops were in service in orbit aboard the International Space Station.

ThinkPads have been praised for exceptional build quality, system reliability, and services throughout their decade and a half of presence in the consumer market. The original design was a collaboration between Tom Hardy, corporate manager of the IBM Design Program, Italian-based designer Richard Sapper (noted then for the design of the Tizio lamp and later commissioned to design a ballpoint for Lamy) and Kazuhiko Yamazaki, lead notebook designer at IBM's Yamato Design Center in Japan. Sapper proposed a design inspired by the Shōkadō bentō, a traditional black-lacquered Japanese lunch box.

The fold-out butterfly keyboard, which appeared in the ThinkPad 701 series, is widely considered a design masterpiece and is on display at the Museum of Modern Art in New York. 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.
