I have a dell vostro 1500 needing a fresh install of xpi got from a friend who had for some reason taken it all the way apart and when he put it back together the screen stayed black when you turned it on. i fixed that, but the keyboard will not work at all so i can't access the bios to change boot order. I have taken back apart and everything seems intact. I am assuming a usb keyboard will not kick on in time to let me access it either. . . so i am stuck
