I am planning on purchasing an ibook G4 from somebody on craigslist. It was purchased in 2006. I know that ibooks were known for having problems with the logic board, but was that taken care of by mid 2006? Also did they fix the problem with the inverter cable going out from the hinge set up on these? I had previously bought an ibook g3 that the inverter cable was going out for really cheap, i just used it until the cable finally quit working and i'm parting it out. That leads to another question, is the ibook g3 battery and charger compatible with the ibook g4? thanks for any responses. I appreciate it and can't wait to get into another mac.
