Hi fellow users. I was wondering if anyone else has a problem with their screen randomly going blank at different points? It just happened to me again just now for the 2nd time today. Mostly happens when my Air is not plugged in. It's like auto sleep or something in the middle of process. Anyone else facing similar issues? i'm about to call support but I wanted a brief understanding of the problem first. Thanks EDIT: Guys, I have added a poll. Please take a second to vote so we can understand how big/common the issue is. Thank You.
