Lenovo ThinkPad

Lenovo completed the ThinkPad brand acquisition in May 2005. As part of the deal, select ThinkPads continued to be sold under the IBM ThinkPad brand for years afterwards. The said brand was however, discontinued mid-way in production of the T61/R61/X61 models. This is also the reason why models after the T61, did not feature the IBM branding.
