Toshiba has finalized its withdrawal from the laptop computer business by selling its remaining stake in Dynabook, its laptop computer division, to Sharp. With this move, Toshiba will officially put an end to its 30-and-a-half-year business.

It also means a complete withdrawal from the personal computer business, both desktop and laptop. This began two years ago when Toshiba sold 80.1% of its PC business to Sharp for $36 million; the deal, announced via PDF file (via PCMag), also provided brand licensing rights. Toshiba then renamed its remaining PC division Dynavision. That, too, is no longer in existence.

"Toshiba Corporation announces that it has transferred 19.9% of the outstanding shares of Dynabook Corporation it held to Sharp Corporation. As a result, Dynabook will become a wholly owned subsidiary of Sharp.

Back in 1985, Toshiba's first laptop was the T1100, which debuted with an Intel 80C88 CPU clocked at 4.77 MHz, along with 256 KB RAM, two disk drives, and a monochrome LCD screen with 640x200 resolution The machine shipped with MS-DOS 2.0. At the time of shipping, it ran MS-DOS 2.11. It also could not run Crysis (partly because Crysis did not yet exist).

Toshiba no longer manufactures computers, but that relationship has not been completely severed. Notably, it still manufactures storage and NAND flash memory products. This includes hard disk drives (HDDs) under its own label and solid state drives (SSDs) from its subsidiary Kioxia. [It has been an interesting path for Toshiba, which acquired OCZ's assets in 2013 for $35 million. Toshiba dabbled with the OCZ brand for several years, including the launch of the high-speed OCZ RD400 NVMe SSD in 2016, but has recently focused on the enterprise market.
