Keyboard keys stopped working, no spill, possible issues?
The other night I was working on my MBP, and all of the sudden keys stopped working on the keyboard. I attached a USB keyboard and all keys worked just fine. This leads me to believe it is a hardware related issue and should be fixed by replacing the keyboard. Some keys work but most do not. I tried removing and cleaning the keyboard, yet to no avail, it still does not work. I have ordered a replacement keyboard, but am not certain it is a keyboard issue. What are the other possible diagnosis and how would I test them?
Is this a good question?
