ThinkPad

Image
ThinkPad is a line of business-oriented laptop computers and tablets initially sold by IBM and now by Lenovo. ThinkPads have a distinct black, boxy design language, inspired by a Japanese bento lunchbox, which originated in 1990 and is still used in some models. The ThinkPad line was first developed at the IBM Yamato Facility in Japan, and the first ThinkPads were released in October 1992. ThinkPads have seen significant success in the business market. ThinkPad laptops have been used in outer space and for many years were the only laptops certified for use on the International Space Station.

History

Image
The ThinkPad was developed to compete with Toshiba and Compaq, who had created the first two portable notebooks, with an emphasis on sales to the Harvard Business School. The task of making a notebook was given to the Yamato Facility in Japan, led by Arimasa Naitoh, a Japanese man who joined IBM in the 1970s, now dubbed the "father" of ThinkPad. The name "ThinkPad" was a product of IBM's corporate history and culture. Thomas J. Watson, Sr., first introduced "THINK" as an IBM slogan in the 1920s. With every minicomputer and mainframe IBM installed (almost all were leased – not sold), a blue plastic sign was placed atop the operator's console, with the text "Think" printed on an aluminum plate. For decades IBM had also distributed small notepads with the word "THINK" emblazoned on a brown leatherette cover to customers and employees. The name "ThinkPad" was suggested by IBM employee Denny Wainwright, who had one such no...

Design

Image
The design language 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, right-angled external case design. Some newer Lenovo models incorporate more curved surfaces in their design. Many ThinkPads have incorporated magnesium, carbon fiber reinforced plastic or titanium into 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. The design was based on the concept of a traditional Japanese bento lunchbox, which revealed its nature only after being opened. 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. Since 1992, the ThinkPad design has been regularly updated, developed and refined over...

Features and technologies

Several unique features have appeared in the ThinkPad line, like drive protection, pointing stick or TPM chips. While few features remain unique to the series, several laptop technologies originated on ThinkPads: Current edit Lenovo Vantage Early known as "IBM Access", later "ThinkVantage"; The suite of computer management applications. These software can give a additional support for system manage (backup, encrypting, system drivers, additional settings). Currently some features replaced by internally Windows 10 features.

It is a simple mechanical sliding cover that allows the user to obstruct the webcam's view. Some add-on webcams and other laptop brands provide a sim...

Use in space

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 (and senator) John Glenn used ThinkPad laptops on his spaceflight mission STS-95 in 1998. ThinkPad models used on Shuttle missions include: ThinkPad 750 (first use in December 1993 supporting the Hubble repair mission) ThinkPad 750C ThinkPad 755C ThinkPad 760ED ThinkPad 760XD (ISS Portable Computing System) ThinkPad 770 ThinkPad A31p (ISS Portable Computing System) ThinkPad T61p The ThinkPad 750 flew aboard the Space Shuttle Endeavour during a mission to repair the Hubble Space Telescope on 2 December 1993, running a NASA test program which checked if radiation in the space environment caused memory anomalies or other unexpected problems. ThinkPads were also used in conjunction with a joystick for the Portable In-Flight Landing Operations Trainer (PILOT). ThinkPads have also been used on space stati...

Popularity

Image
ThinkPads have enjoyed cult popularity for many years, with older ThinkPad models remaining popular with enthusiasts and collectors, who see them as durable, highly usable machines. Aftermarket parts have been developed for some models, such as the X60 and X200, for which custom motherboards with more modern processors have been created.
