and if so, anyone know the rate? My 2.16ghz 15" MBP has been acting up for a while now, and its out of warranty. It used to be that if I had to restart my MBP or turn it off and then on again, it wouldn't do it. Instead, I could hear the fans going, but the screen would be blank and not boot. Now its doing it when I put it to sleep and try to wake it. I'm sure its a logic board issue, but want to be sure and want Apple to look at it and tell me what the problem is. I only had to deal with Applecare once and it was a pleasant experience, so I hope this goes well.
