Not quite its actually the kernels advanced power management process. What normally happens when your machine is idle, has nothing to do, it will execute a special no-op instruction which, as the name suggests does nothing at all except to keep the machine ticking over. Now what the kapm-idle process does is it runs whenever the machine is idle and replaces these no-ops with a special instruction to cause the processor to shutdown some parts to conserve power, and also as a side effect reduce heat output. Cool huh! > I'm using Mandrake 8.1 with 2.4.13-12mdk All recent kernels have this option.
