Notebook major Toshiba announced a recall-drive of all notebook PCs it sold that are based on Intel's Huron River platform, consisting of processors based on Sandy Bridge architecture and Cougar Point chipset, after Intel announced a critical design flaw with the chipset. In a consumer notice, Toshiba advised current owners of affected notebooks to return the notebooks for a full refund. It also asked users to backup data and remove all personal, confidential, or proprietary information before returning the units.
