Hello all, I was wondering if some may be able to help me. I recently puchased a Toshiba 490cdt laptop from an ebay auction. When I turn on the power I imediately am asked for a password against a black screen. I don't even think it is making it as far as the bios. Iread another thread last night and found some one had a similar problem w/ a dell laptop. Can anyone help me out?
