Processor cycling

If the computer is not doing anything for a few seconds, it reduces the power consumption of its microprocessor. The microprocessor comes back up to speed instantaneously when you resume work. This feature is called processor cycling.

You don’t need to do anything to use the processor cycling feature. But if you notice that one of your programs performs very slowly, you might want to turn off processor cycling while using that program.

To turn off processor cycling, follow these steps.

1.Choose Control Panels from the Apple menu, and open the PowerBook control panel.

2.Click the Options button.

3.Click “Don’t allow cycling.”

4. Close the PowerBook control panel.

To turn processor cycling back on, click “Allow cycling.”

You may notice other effects of processor cycling. For example, if you have open programs doing something in the background, processor cycling may slow those programs down. You may also notice that the Alarm Clock is updated irregularly or that the wristwatch pointer appears more often. These changes do not indicate a problem with your computer.

When you turn processor cycling off, the computer drains the battery faster. The computer may also become very warm to the touch, especially on the side beneath the keyboard. These changes do not indicate a problem with your computer. However, you should keep processor cycling turned on whenever possible.

Important: To conserve battery power, turn processor cycling off only when using programs that it interferes with. Turn processor cycling back on again as soon as possible.
