I have another laptop that is my sons. He brought it to me hoping I could fix it. It is a Toshiba Satellite M45-S265. When I turn it on, it shows a black screen and its asking for a password. This laptop belonged to my dad and I gave it to my son when my dad passed away, We have no idea what password the system is requesting. Can anyone offer a suggestion? We cannot get past this screen into bios or anything else and there are no disks with the laptop. Thanks, Lylasia
