The ThinkPad T series is a line of laptop computers.

The naming convention for the T Series was changed by Lenovo following the release of the ThinkPad T400 and T500 in July 2008. The Txxp models (like the T61p) were replaced by Lenovo's ThinkPad W Series laptops. Designed as mobile workstations, the W series grew to become Lenovo's line of performance-oriented laptops. The T series remains Lenovo's premier line of laptops, aimed at corporate and enterprise users and is praised by users for its outstanding Linux compatibility. The T-p lineup later returned as an irregular T##0p line with only T440p, T460p, T470p and T540p models.
