     There _may_ be a fix your tools can handle. If the KB Encoder IC or 
the IOU IC is loose or has pins making poor contact, you could get the 
symptoms described.

     Open the case and locate the KB Encoder (a big, 40-pin IC on the 
right side of the motherboard just to the right of three ROMs). Use a 
small, thin-blade screwdriver to scootch up the IC. (You want to get some 
lifting for all pins, even if you end up just removing the IC.) Press the 
IC back into the socket.

     Do the same with the IOU (a big, 40-pin IC just to the left of the 
three ROMs).

     The idea of lifting up and re-socketing each IC is to let the socket 
contacts scrape a fresh connection with each pin on the IC.
