I went in today to get a replacement charger because of issues with the sheath coming apart near the magsafe connector. Even though I had purchased Apple Care, the Genius still tried to tell me it was not covered and that it was notmal wear and tear, but when I asked to talk to the manager, he went to the back, came out a few minutes later, and said they would go ahead and cover it. Anyway, as a part of the appointment, I was asked to bring my machine in and he ran diagnostics on it and said the battery had some issues and it would be covered under warranty, but that it would take 3-5-7 days to get it done. Is that pretty normal, or is there a way to get it done sooner? Is it ever possible to get it done on the same day? Thanks.
