Hi! Bought my iBook 9 weeks ago, after 3 weeks the combo unit started to **** up. Then slowly everything just went dead, screen and all. Finally my iBook wouldn't even start at all. I got it to an Apple store and they said the problem was the motherboard. It took three weeks to get it fixed. I got it back 3 weeks ago and at first everything was ok. But now som minor errors are starting to appear again. The Modem Icon in the upper menu dissappears when running some programs, and the only way to reach it is through system preferences/internet connect. Maybe not a big thing, but quite irittating in the long run. iTunes is also starting to act weird from time to time. It spontaneously opens and sometimes when running the sound just goes off but the song keeps playing. Weird. Could this be a sign of another hardware problem? Or maybe OSX instability? Thanks in advance for any help.
