Hi everyone. I received my black MacBook last Friday from Amazon, and out of the box it's been having problems. It has that oh-so prevalent CPU whine I've been hearing about (no pun intended) in the MBP. On top of that, it refuses to sleep after any designated time I set. I've tried resetting the SMC, PRAM, and running Repair Permissions. I called Apple Care and the only thing they could tell me was that there's a hardware problem and I need to bring it in to a Mac Genius. He also said I wouldn't be able to do a swap for a new one at the Apple Store because I did not purchase it from there. Fair enough, but that'd be a bit less annoying if I was able to exchange it from the seller I did purchase it from. They don't sell it anymore, only the new 2.4ghz model. They won't do an exchange on Amazon since the new one has a different serial number, and I can't get a straight answer on whether or not they'd charge me a restocking fee if I just decide to return it. Maybe I'm asking too much, but I don't think I should have to have my brand new computer repaired. It's not only that though--I'm a student and I need a computer! I can't wait for it to come back from repairs. I don't really see what the problem is with doing a simple swap. I mean, all of the computers with this serial number are now being sold as refurbished anyway, since it's an older model. I guess, essentially my intention is to ask if anyone has had experience with Amazon's return policy, because I'd consider returning it if I could be assured that I wouldn't be charged a fee. I'm fine with this model, so I'd consider getting one refurbished since (to my knowledge anyway, correct me if I'm wrong) they have the same warranty as a new one. If I do decide to keep this one, what should I expect from my appointment tomorrow with a Mac Genius, and do I have any chance of getting a replacement? If not, how long would I be without a computer? Sorry, that was pretty long... Thanks guys.
