Apple Macintosh PowerBook 150 - Manual (Page 90)

Power conservation
Your PowerBook keeps track of the power source you are using and can
change the power conservation settings to maximize battery conservation and
performance for both the battery and the power adapter.
To change the power conservation settings, 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.
3 If necessary, click the Auto button to select it.
When Auto is selected, the computer will automatically use the settings you
specify in step 5 whenever the selected power source is being used. (You can
temporarily override your settings by returning to the PowerBook control
panel and selecting Manual.)
4 Choose a power source in the pop-up menu.
5 Drag the sliders to the settings you want for the selected power source.
To use the preset power conservation settings for the selected power source,
click Default. See “Adjusting the Battery Conservation Settings” earlier in this
section for more help.
6 Close the PowerBook control panel.
