This morning while my MBP was in sleep mode, I heard a sound like it was waking up, but I didn't touch anything. Anyway, it then made another sound that it turned off. Thinking that was odd, I turned it on. The MBP light indicator would boot for about 1 sec and then turn off. I tried to reset the PRAM and SMC, to no avail... same result. Nothing appears on the screen. I have an Early 2008 MBP and the Applecare expired May 2011. I'm guessing a logic board replacement is needed. I also remember that Apple is offering to replace the board for faulty 8600GT cards. Do you think the graphic card is part of the problem, so that Apple can replace without costing me a lot of money. The only good thing out of this is that because I upgraded to Lion last Thurs., I had backed up all my data already.
