It might help to borrow a "real" PS/2 keyboard, but I suspect that the fault
(or faults) is on the motherboard - probably a bad joint at the connector or
a damaged keyboard chip (may be integrated into the chipset if it is not a
40-pin "aircraft carrier" chip near the connector.) Also look for a "pico"
fuse between them. It should look like a blank 1/4 Watt resistor, with a
marking like "2A" on it. Use a low-voltage ohmmeter or "beeper"
continuity checker to find and test it. Also check continuity through the
adapter and cable to the keyboard (where the cable connects inside the the
keyboard.)
With a little luck, you will have to resolder/repair/replace the
connector or fuse. With worse luck, you can probably get a replacement
keyboard chip from Dell.
