I just dropped off my powerbook for service at an Apple Store. 6 months old and after booting up, it immediately goes to sleep. Tried all the tricks to try and fix. So they determine that is it most likely the logic board. Now my first question is this. For anyone that has had this or similar service how likely will they wipe out my hard drive and data? Doh , I backed up everything, EXCEPT all my photos in iphoto (family, vacations, etc) - irreplaceable. Forgot, forgot, forgot. Is there anything I can do now or just pray? Second question: They needed my main password to of course do various installs and whatever else comes up during service. In doing so, should I be worried about my keychain data (passwords for cc, bank accounts, logins, etc.) Yes it is private and I assume the technicians are professionals, but should I worry?
