13 inch MacBook Air won't power up
I've got the July 2011 13 inch MacBook air. Was using it this morning. Worked fine. Came back to my desk later, won't power up. Completely dead. It was connected to its power cord. There is a green light but it's just dead. Power Button won't start it up. Only option I'm thinking is to bring to an apple store. Any other possible suggestions before I do that?
MacBook Air, Mac OS X (10.7.3)
