TCS changed its brand name to Dynabook in January 2019.
The action means that Toshiba - a consistent name in PCs and laptops since 1985 - now has no presence left in the PC market, while Dynabook has become a wholly-owned subsidiary of Sharp.
Toshiba's first laptop was the T1100, released in 1985. Over the decades it had considerable success with its Satellite, Qosmio, and Protege devices.
