What on the logic board blew up? Why does it work now?
This is a strange one. I've had my macbook pro since late 2010, one month out of the extended apple care and boom... wont turn on. Seems a bit like a ticking time bomb, no?
Paranoia around planned obsolescence aside, something strange happened. My symptoms were hinting towards a logic board problem (battery charging ok, indicator turning orange when charging, only turning green when fully charged or doing SMC reset) still in any case never powering on, plugged into the mains or not.
Being out of warranty, I decided to open up my machine and take a look for myself. Sure enough, a capacitor or something had blown, taking a few things around it out too - see these pics:
That whole area appears to control the battery interface with the logic board, so situation seemed a no go without a new board or some annoying soldering. (Anyone happen to know what capacitor this is supposed to be? incase I do have to repair?)
HOWEVER, I put my case back on, turned the machine over, opened the lid and it just... turned on. Like it was waking from hibernation.
What did I do? nothing. Unplugged the keyboard connector and put it back. blew away a little dust. You see from the pictures that this is a real hardware issue... so how on earth does it manage to turn on now!?
Is this a good question?
