Hello everyone I am having a screen problem with my late 2010 11" macbook air. this has never happened to me before. After i wake up my air from a deep sleep the screen looks completely fine for like a second then it shows me the purple grainy screen. This only happens if i wake up my air after 10+ hours of my air being in deep sleep. I have already tried to reinstall os x lion and it is still going on. If anyone has any clue what this is please help me out! Much appreciated guys! I also wanted to let you know that once i restart my computer or have to manually shut it down by holding the power button. The screen is back to normal. Please help!
