    I have an old pc about the early 90's. On the front of the system is a key lock/unlock. It's to unlock the keyboard. I don't have the key, so my question is how do I fix this?

    Hi and welcome to TSG,

    If the lock does not also lock the case shut, you should be able to open up the case and disconnect the lock switch from the motherboard. The keyboard should now work no matter how the keyed switch is set.

    Hi. I tried that and still have the same problem. I even tried a jumper to see if that would work. Windows does not start up. The error is at the beginning when the system checks everything.

    If the key switch has only two wires going from it to the motherboard, the only possibilities are that the two wires or connect to each other not. I believe that most motherboards of that era disabled keyboard input when the two pins are shorted to each other

    What is the exact wording of the error message?

    Am I safe to assume that the computer uses 6-pin Mini-DIN sockets for the keyboard and mouse connections? If so, are you using a keyboard with that type of plug on it or does it have a different plug and you are using an adapter.

    Have you made sure the keyboard is plugged into the keyboard socket and not the mouse socket? Some motherboards may be finicky about that.

    Do the indicator lights on the keyboard blink when the computer is first turned on?

    Hi Chuck. I found out what the problem was. The turbo boost was connected with the keylock. Sharing the same pins. There are five pins on the board that reads "keylock". The key only uses two of them. Then there's three open. I moved the turbo two another set of pins, and now things are working great. Thanks for your help. Good day
