Using the battery conservation options | Apple 145 specification

More about automatic sleep

The Battery Conservation slider controls two different power conservation features: system sleep and hard disk sleep.

mSystem sleep is a state in which your computer uses only the power it needs to maintain the contents of RAM. (The contents of RAM include any open programs and documents, and various control panel settings such as the clock time.)

mHard disk sleep stops your computer’s internal hard disk from spinning when it isn’t being used.

If system sleep is in effect, so is hard disk sleep.

The table indicates how the battery conservation settings correspond to sleep times.

Minutes before sleep if you choose:

Hard disk	15	4	2	0.5

Using the battery conservation options

The Battery Conservation section of the PowerBook control panel includes a button labeled Options. Click this button to see more options that affect your computer’s power consumption.

Don’t sleep when plugged in

If the power adapter is plugged in, you can prevent automatic sleep by clicking “Don’t sleep when plugged in.”
