    How did you determine that the logic board is at fault? What are the symptoms (since you haven't told us anything else)?

    If it really is a logic board that is defective, you will not be able to just replace one component on the board. The entire board has to be replaced.

    Go to and look up your model G3 iBook. You can get some idea of what it would cost and what's involved to replace the board if you did it yourself.

    Does the hard drive spin on your ibook? Usually that is a red flag for a faulty logic board.
    Yes my name is Jaguar.
    No, it is not a joke.
    I don't find your "I'm a cheetah." joke funny.
