Processor cycling
If the computer is not doing anything for a few seconds, it turns off its
microprocessor. The microprocessor comes back on the instant 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.
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:
1 Choose Control Panels from the Apple (
K
) menu and open the PowerBook control panel.
(Or use the Power Settings module in the Control Strip to open the PowerBook control
panel.)
2 Slide the switch to Custom.
