So a few months ago apple told me that my logic board was kaput and needs to be repaired. I was advised that this would be around $280 dollars. I have been able to run the computer for a few months now, only by power cord. usually fighting with it to get a green light on my power cord. Went away for the weekend and came back to no light from the power cord whatsoever. computer wont turn on. i understand that this is normal but can i revive it without going back to apple?
