OK. I sold my MacBook Air to a co-worker some months back. Turns out he wanted it so he could do some hardcore media conversion - I'm talking Handbrake and DVD ripping and the whole nine. Upon finding this out, I cautioned him that there was a chance he could kill the lil bastid, he didn't listen, now he says it won't turn on. I advised him to bring it to me so I could take a look at it. Symptom is that the power button does nothing, apparently. Before I get into it, what do others think it might be? Inverter?
