Acer 5100 will boot to a new XP install which it did mostly on it's own as I cannot use keyboard or mouse. (Not sure if this matters or not but this is a used hd with a gateway install on it not acer)I cant reload anything from the cd as I need to push a button too. I tried a usb mouse instead of the pad on the machine but no use. I even unsoldered the cmos battery for a day and place back in to try to reset the bios, nope. One other thing is on occasion when it boots I get no video. So I have to hold the power button down to shut off and try again whatever the problem is. . Can't access the bios that wants F2 button. Any ideas on this would be helpfull
