Hey all, has anyone else with the 2011 15" 2.2GHz Core i7 MacBook Pro experienced graphics card crashes? My first unit was plagued with them, I returned it after a long battle with Apple (since I couldn't replicate the issue in the 30 seconds they look at it in the Genius Bar) and was given a new unit, which has been decent until recently when it had its first crash, locking up with a garbled pattern on the screen. My first unit crashed under both OS X (SL and Lion) and Windows 7, my new unit has only crashed under Windows 7 so far (doing work for my Masters degree, thankfully I'd just saved), but it doesn't bode well for when I need to start doing video intensive work under OS X for my job again. With both machines I've also had sleep issues- they've both been very slow at waking from sleep, my first machine often took 10-15 seconds for the screen to light up and become usable, and would thrash the hard drive upon lifting the lid. My replacement unit takes 5-6 seconds and does, as before, rev the hard drive before waking, but is much quieter about it. It occasionally does wake quickly, but more often than not, I have to wait for it to revive. Neither unit matches the ~1, sometimes 2 second wake time of my girlfriend's 2010 13" MBP, or her new 2011 13" Core i7 (a replacement for her 2010 13", which was killed in a Genius Bar repair). Have I been incredibly unlucky and received 2 dodgy units? Or are these crashes plaguing a significant number of 2011 15" owners?
