My daughter just got a free 12" G4 ibook laptop computer. The reason why it was free was that back-up battery needs replacement and the apple retailer dealer told my friend who gave my daughter the computer said it would cost too much to fix. So I went to apple website and it states that 12" G4 ibooks do not come with backup internal battery. So my questions is: do this computer has internal backup battery or not and can I repair this computer myself? The computer works fine when i have the power cord attached to the computer. thanks for the help. ken
