Long story short. Mid-2005 iBook G4. My battery stopped charging while plugged in with the AC. I tried a new battery and even a new AC, but nothing worked. And when the battery was charged, the iBook would shut down out of nowhere, pretty often. I took it into an authorized repair shop, luckily, it's still under the applecare extended warranty. The guys there tell me that they have to ship it off to Apple for repair and that the motherboard will probably be replaced. My question: Will i lose my data? They said there is a chance of that happening, and want to charge me $80 for data transfer before they ship it off for repair. I do have a lot of stuff on the computer that is not backed up, so i might have to do that, but i am wondering what the chances are... and if i should risk it. I'd have to buy an external drive to transfer stuff too, so my under-warranty free repair is going to end up costing me a few hundred dollars (because i had to buy a new battery and plug, too). There is always a chance they just try to sell that theory so they can make some money. I don't know much about hardware, and maybe they can tell. Are they taking advantage of me? So, new motherboard=erased data? yes, no, maybe so? Thanks in advance.
