I have a Dell Studio 1557 laptop. Once upon a time I set the Setup password and I have since forgotten it. I called Dell and they were absolutely no help - - -he had not even heard of a password for the setup utility. The laptop does not have jumpers on the motherboard so that option is out. I have read that removing the internal battery will cause the computer to forget everything........is it really that drastic and is that the easiest option. When I enter a password I get an error message 13931 and the computer service tag. Suggestions ??
