Processor cycling

If the computer is not doing anything for a few seconds, it reduces the speed of its microprocessor. The microprocessor comes back up to speed instantaneously when you resume work. This feature is called processor cycling. Processor cycling conserves battery power. Your computer automatically comes with processor cycling turned on, and it is highly recommended that you work with processor cycling on.

Note: Processor cycling does not occur when your PowerBook is docked in a Duo Dock or Duo Dock II. See Chapter 8 for more information on Duo docks.

In a few cases, processor cycling can cause programs to slow down. If a program performs very slowly, you can turn off processor cycling temporarily. Follow these steps.
