Apple 280C manual Choosing Custom options, Battery Conservation settings

The time it takes for each feature to take effect depends on the settings you choose. If you drag the slider toward Better Conservation, it takes less time for the system to sleep, the hard disk to spin down, and the screen to dim.

The table indicates how the battery conservation settings correspond to the time before each power saving feature takes effect:

Minutes it takes if you choose

	Conservation				Performance
System sleeps	2	3	6	8	15
Hard disk spins down	1	2	3	6	8
Screen dims	1	2	3	4	5

Choosing Custom options

For more options that affect your computer’s power consumption, slide the switch to Custom in the PowerBook control panel.

Slide this switch to Custom view.

In Custom view, you have these additional conservation options. (However, reduced processor speed is not available on the PowerBook Duo 280 and 280c.)

Battery Conservation settings

The Battery Conservation slider works as described in the previous section. In Custom view, you can also use three individual sliders controlling system sleep, screen dimming, and hard disk spinning down.

As you drag the Battery Conservation slider, the three individual sliders change. Likewise, when you drag one of the three individual sliders, the Battery Conservation slider is affected.
