Chosen Solution
Hi guys. I’m about to have a heart attack here. I was doing some routine cleaning of the inside of my macbook, something I had done many times before. This meant removing the upper case by disconnecting the keyboard (silver connector). I then proceded to put it back together, connected everyting and powered it back on. It booted up by neither the keyboard not the trackpart worked, so I thought that I had probably not connected the upper case correctly. I re-dissassembled and reconnected the upper case wire. Tried powering on again but once again no keyboard or trackpad. Tried again but now I don’t even manage to get it to power. If I connect the power adapter, the light does go on the connector but nothing happens. I’m really scared that I killed my laptop. Any advice? Thanks! Update: Just tried powering it on by shorting the two soldering points next to the fan and it works. Phew!!! So that means that it’s probably a problem with the keyboard, or maybe just the cable or the connector? Given that there were no spills or anything of the sort, is it likely that the keyboard got damaged or could it be just the cable from the keyboard to the logic board? However, being the pessimist that I am, is it possible that the connector in the logic board got damaged?? :-/ I’d appreaciate your experience on this which will hopefully help me get a good nights sleep!
The main suspect here is the the keyboard to logic board cable. Try reseating it as sometimes it looks like it all the way in but is not.
Thanks for the link, chssvl.
