Won't start after upper case replacement - more info?
Replaced upper case on my MacBook A1278 late 2008 to repair inoperative keys following too much liquid cleaner. New case has backlight, logic board has corresponding socket. No response to power button after re-assembly. Have seen sizeable correspondence on this and other sites about fully seating the keyboard ribbon connector. Fiddled with it without success. Tried the tape handle trick to no avail. I have another newer Macbook and the two look seated the same depth to me. Any other ideas or tricks to get a response?
Is this a good question?
