Hey guys, I hope this is the right forum to post this. Last night I realized I have a few weeks left on the factory warranty on my 17" MacBook Pro. So I went ahead and bought AppleCare for it online. Sure enough, I woke up this morning and the screen won't turn on. Everything else seems fine though. I searched everywhere and tried and troubleshooted everything possible and still no screen. My main question is, since Ive never bought AppleCare before, when the box gets here from Apple, Im assuming I have to register it somehow. Im also (hopefully) assuming I can do it online. The closest Apple Store is a little over an hour away and I want to take it out there this weekend assuming I get the box before this weekend. When you take a product in for repair, do they fix it on the spot if they can? If not, do they take it to ship it off or exchange it? If they take it do they give you some sort of replacement? I cant afford to be without a computer for a day. Im really concerned about this. Also, I installed 4GB of RAM a few weeks after I got it. Will this void any repairs to be made? I hope not, because I sold the 2GB that came installed. I'm really worried about this. Any and all advice is much appreciated. Edit: Just saw online where I can register it with AppleCare once it gets here.
