If you're not doing anything and there's a lot of green or red and not a lot of black, you can look at what processes are using the most CPU. If it's mostly black (assuming you're not doing anything), then the CPU is not busy, and you might want to investigate some of the other ideas people have had; if it's in a warmer environment, or on a different surface, or if you're running MacOS 9 applications, or whatever.
