Hello there, I have Toshiba Satellite L305D-S5893 laptop which has Windows Xp installed on it. Recently I tried to update the BIOS of the computer and for that I visited the official website of Toshiba but when I started downloading the update file, the computer shut itself down and now when I boot the computer, it does not shut down. When I select shut down option from Windows, it reboots the system. So if anybody has any ideas about Toshiba satellite L305D-S5893 shutdown problem or bios update problem, then please share some information which might help me in solving the problem. Thanks in advance.
