I took my Powerbook to the Apple Store for the problem I have in this thread and the genius said it would need to be sent away to have the keyboard replaced. Since I need my PB a lot for the next couple weeks, I declinded, as this is a problem I can live with temporarily. He gave me a case number, and said I can either drop my PB off at the Apple Store when ready, or call AppleCare, give them the case number, and they'll send out a box for me to send it back. Since the Apple Store is in St. Louis's busiest mall and it's a couple weeks before xmas, it's obvious what I'm gonna do. I've never sent anything back for repair though. How does this work? Do I have to pay for any of the shipping? Is it overnight shipping or ground? Thanks.
