The air was working fine for the first couple monthes or so. But recently the air has been freezing, shutting down on it's own, and not waking from sleep A LOT. Its almost everyday now that I have to press and hold the power key because the computer is either completely frozen or won't come out of sleep. And, like I said, it boots down by itself a lot too. I was writing an essay for one of my classes, went to get a cup of water, and when I came back it was off. What could be wrong with it? Is this normal for flash-based systems?
