I don't know what's wrong with my macbook pro but I'm getting really pissed and irritated. I bought this Macbook Pro in late December 2010. Specs are as follows: MAC OSX 10.7.2 2.66 GHz Intel Core i7 8GB DD3 RAM 500GB HDD I updated to Lion as soon as it came out. I don't know if that's the problem or not. But it started happening two months ago and getting worse. The screen would go black but the laptop is still running. I can see the keyboard lit and hear it still running. Now occassionally it just freezes and the screen goes blank while I'm using it. Only way to get it back to normal is shut it off and turn it on again for both instances. I brought it to Apple for diagnostic and they couldn't replicate the problem. They ran some diagnose tests and results came out to be fine. I don't understand what the problem is. I need help. Have you guys had this problem before?
