Hello Steve, I agree that the computer should be left off, though the next best step is to let an Apple certified technician have a look at it. If there isn't a store very near, you could call Apple and they'll arrange for you to send it in to them. I expect the problem's not very serious - might be as simple as cleaning dust out of the fans. Another possibility is that it's somehow forgotten how to keep itself cool, and resetting pram and nvram will solve the problem. I recall we just had some emails on the list about doing just that. The steps are likely identical for that laptop as they'd be for any G4 desktop system. Best of luck with it.
