Not sure how to describe it in one sentence, hence the odd topic title. Sometimes when I open my macbook air 11, nothing seems to be happening. The screen appears to be staying completely black. However, I noticed that my volume buttons do make a sound when I press them. Looking up closed to the screen, I can actually see my desktop and everything on it, but it's like the screen is on 1% brightness. It seems completely black, but only when you look carefully from up close, you can actually see the desktop and windows on it. Closing the laptop and reopening than turns on the screen completely again. Does anyone else suffer from this problem?
