So I have a II+ and the keyboard was mostly working but there were a few keys that would either not work, repeat, or just occasional work.
I dripped a few drops of deoxit down the plungers and all the keys that were not working started working. Next I recapped the power supply and the computer boots but none of the keys are working but the power light is working on the keyboard.
Where should I start troubleshooting ? Keboard encorder or system board?
What should I be looking for?
