FYI, This CERT Advisory is worth perusing if you're a Lenovo owner.

Thanks...good info...I went to the list and my Lenovo model is not on the list.

But I remember one ThaiVisa member who asked some laptop related questions in another thread had a Z51-70 and his computer is on list. Going to the Lenovo support web site and looking under the drivers for the Z51-70 I see it has a BIOS update which was released 28 July 15 probably to fix the issue. Just another reason to always be sure to use the drivers from your computer's support website and check the site periodically to ensure you have the latest drivers specific for your model loaded (to include firmware updates) versus using generic Windows drivers.
