Hello guys, seem to have a problem, when I try accessing the bios of this acer EXTENSA 5220, it tells me system error 11263??? does anyone have any clue on what I can do?????.

You can call acer, tell them the code & provide proof of ownership and they will give you an unlock code.

Or you could trawl the web for a solution.

By the way this is a hard drive recovery and repair forum and has nothing to do with laptop bios passwords.
