Well, it was the airport card. Thanks to the wonderfully attentive genius at the apple store, he actually ran into the back, opened it up, and removed the airport card while I waited. They're ordering the new airport card, and will install it at a later date. I never use it, so it's OK with me, at least I got to bring my mac back home with me where it belongs.
Anyway, just restored my backup, and i'm assuming I need to recreate my clone? It's an exact backup of what was cloned before, but I'm thinking maybe things won't sync up quite right unless I recreate the clone?
