I got my brand new Air yesterday from the Amazon deal. I used migration assistant on it overnight, it was fine when I opened it this morning. I closed it up and went to work, and now it's completely unresponsive. The magsafe is lit up so I know that's not the issue, but it simply won't turn on or give any response at all. I tried everything on the Apple troubleshooting page including resetting the SMC, is there anything else I can do or am I doomed to the genius bar?
