I've been using my MBP for ~1yr. I have an early 2008 model. 2.5Ghz, 2GB RAM and 250GB HD with 8600GT 512MB. Out of nowhere my laptop just wouldn't turn on. I hit the power button, then the usual buzzing of the drive comes and the sleep light turns on for like 2secs and then it just turns off again. It basically does the first 3sec of bootup and shuts back down. If I hold the power button down, after a while the sleep light flashes real fast for like 3secs and then it just turns off. I've searched and searched....and nobody else has the exact same problem. Anybody know what it means? I've reset the PRAM or whatever and everything but it didn't work....and so I took it to one of the only genius bars here in Shanghai, China. The guy took out the ram and reseated it, but it was no use. So then I asked him what else could be the problem...and he mentioned something about 2 boards. 1 being under the left speaker and a 2nd larger one below the whole laptop. I'm assuming the 2nd one is the Logic Board because he said if THAT was the thing that was broken, it would easier to just throw away the laptop because the repair would cost 7000RMB(~1000USD). But he said if the 1st one, under the left speaker was broken, it would be easier to fix and would cost much less. Anyone know what he's talking about? I left the laptop there for them to scope it out, so I'm just asking you guys what you think. I can just buy a newer one, but what I'm worried about is my hard drive. It has some important stuff in it. So another question I'm asking is whether or not this could be a hard drive failure, rather than a logic board one. And if IT IS a logic board failure, would it possibly affect the hard drive. And whether or not they format the hard drive at the genius bar as part of the testing process Another thing to add is that it happened 1week after warranty expired.
