MacBook Air keeps waking up from sleep thinking it has a second display connected

[cstromme]

My girlfriends Air has suddenly gotten a weird problem lately. Every now and then when she wakes it from sleep it seems to think that it has a second display connected to it. Even rebooting doesn't always solve the problem.

She has never used an external display with it before. The port looks clean (I thought there might be something there causing a short) and as far as we know there hasn't been any tinkering with any system files on her computer.

Anybody ever heard of this problem before? Or have any idea how to fix it?

Makes me wonder if there is something bad with cable connecting the port hatch door to the motherboard; however, I would think that happen all the time and not just waking up from sleep. Can you correlate it with the position of the hatch door?

No clue on how to fix, but I did get interested in the story when you mentioned "girlfriends." I was quickly disappointed when you said "she" meaning it was only one girlfriend and not multiple girlfriends.
