Keyboard and trackpad not working.
Just recently changed my fan in my MacBook.
After rebuilding the laptop my keyboard and trackpad is not working/non responsive.
Usb keyboard and mouse works fine.
No light on capslock on keyboard.
It boots up fine using the power button on the right of the keyboard though.
It worked perfectly fine the first time i rebuild it but had to disassemble it again because of what i thought was a bit too loud fan noises (and high idle temperatures, since i replaced thermal paste as well).
I figured it could be three problems.
1) the topcase (i've now ordered a new one and waiting for it).
2) the ribbon cable (which will be coming with the top case)
or 3 (aka the problem i don't want at all), the connector on the logic board.
How big are the chances that it could be number 3? I'd hate to have to change logic board.
Any other tips i could be doing to get it to function again would be appreciated.
Is this a good question?

Just one question: did you try to connect the top case to the logic board while the machine was powered ?

lemerise; of course not.
I can happily report that it was indeed the top case that was fried. Not entirely sure how (maybe static even though i take the necessary precautions). Exchanged it and all is well.
