Well, at work we have some dell computers that we got from another office and some of them had boot passwords so we couldn't set them up. I pulled the jumper off and booted and it let me in to the BIOS I was able to disable the password, shut the computer down, put the jumper bacc on and everything was fine. It no longer asked for a password. I don't know if laptops are the same way but I know for a fact it works with desktops.
