ThinkPad, also known as "ThinkPad" in Chinese, was a portable computer brand under the IBM PC Division before 2005. Reliable features enjoy a high reputation in the industry. After Lenovo acquired the IBM PC Division, the ThinkPad trademark was owned by Lenovo. Since its inception, ThinkPad has maintained a classic black appearance and has its own unique insights into technology, such as: TrackPoint (pointing stick, commonly known as the little red dot), ThinkLight keyboard light, full-size keyboard and APS (Active Protection System, active protection system) ).

Thinkpad is the most popular portable computer among developers of the open source operating system OpenBSD, and the ThinkPad X40 is one of the most supported portable computer models.
