After cleaning the fans and reassembling, computer starts fine but keyboard and touchpad wont work. Everything else seems to work fine. I followed step by step instructions on manual. Connected upper case cable twice, still won't work. Might be connecting something wrong?
Any tips or advise?
Thanks!
Is this a good question?

Quite possibly you loosened or damaged the ribbon cable or connector, reexamine them for cuts/nicks and a poor connection. (You might need to use a magnifying glass)

I have examined the ribbon cable and connector thoroughly and there doesn't seem to be any cuts. The strange thing is that sometimes they work fine and all of a sudden they stop working for several days. Any other ideas?

Try replacing the cable. If that doesn't work, replace the upper case. If that doesn't work, replace the logic board.

Since that cable is built into the keyboard, how do you do this? Why replace the uppercase rather than just the keyboard? Nothing indicates that it needs a logic board replacement.
I was referring to the cable that connects the upper case to the logic board. And, yes, thank you for correcting me. I did mean the keyboard.
