Well, I brought my Powerbook in to get repaired at the Apple Store and all the guy seem to do was repair the disk permissions. Problem was not fixed. Second time, brought it in and they finally decided to send it in to repair the temp sensor. It's been a full two weeks that my computer has been in for service, the part has been on hold since Jan 4th. This is the most frustrating tech support experience I have ever been through. Calls to Applecare just result in, "Sorry, Sorry, Sorry" but no action. Is there any other person we can contact? I go back to school in 3 days and i'm required to have a computer.
