    my ibook g4 seems to be overheating quite quickly.

    I've heard that ibooks should not be used for long on charge which is understandable. But my problem seems to be even when its not on charge. Any Ideas?

    No idea why, but mine did this quite a bit in it's later years (4-5 years old by that point).

    I think the fans stopped running at low speeds, as the computer would be dead silent, then the fans would kick up to full speed as the thing felt like it was approaching 2nd degree burn amounts of hot.
