Keyboard not working.

I have a computer that gives a keyboard error eachtime it starts up and won't allow the computer to finish booting. The error says to hit F1 to continue but obviously that won't work. I have tried a couple different keyboards on the machine and none of them work. The keyboard was working one day and now it's suddenly not working. So my question is if anybody knows of any hardware I could use to hook my keyboard up a different way? Say like through a com port or if they sell cards to plug keyboards into. The keyboard currently plugs into a fat plug in the motherboard. Thanks,

You can try opening the PC, and pushing down on the keyboard controller chip.  On older PC's these were socketed chips about 1/2" X 2" black.  Otherwise, go the USB route.
You could get a card that has a ps/2 port on it, or check to see if your motherboard has a ps/2 keyboard port or a header to add one. There are also usb keyboards
did someone plug the keyboard into the mouse port? Try swapping them...

Might be that the keyboard fuse is blown, this is a fuse in the 5v power line to the keyboard so if you are getting no lights on the keyboard, either the quick flash they do at boot or not being able to turn any on with the cap/scroll/num lock keys then I would suspect the fuse. It is very near to the keyboard socket on the motherboard usually and is usually marked F1 on the board, it probably won't have any markings on the component at all, no color bands or figures, the ones I have seen have been yellow, brown or blue. You can probably get away with bridging it with a piece of wire.


Road Warrior
RoadWarrior's suggestion may be correct.  This can be caused by hot swaping the keyboard.  You  may want to get help with this if you are not good at soldering.  I have done it before, but the newer systems may not be as evident as to this component.

We ended up going the USB route. We went out and bought a USB keyboard and USB card. That seems to be working fine. What is wrong with the keyboard plug I couldn't tell you. The keyboard was in the right spot though. It had been plugged in there for weeks before this happened.
