I have a panasonic cf-51 laptop that i’m working on and it seems that some keys will not function. Also when I connect a external keyboard it seems to behave the same way. I have also replaced the keyboard with no luck. So where I am now is I have a laptop that will boot to the logon screen but ctrl-alt-del will not work. I also can’t access the bios because it’s password protected and the keyboard will not accept the number keys.
