Apple Macintosh PowerBook 150 - Manual (Page 85)

The easiest approach
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.)
The PowerBook control panel opens in Easy View. You can also choose
Custom View for more detailed options. See “Choosing Custom Options”
later in this chapter.
2 Drag the Battery Conservation slider to the setting you want.
Better Performance allows you to work with the fewest interruptions (that is,
the computer going to sleep, the hard disk spinning down, or the screen
dimming). If you can’t plug in the computer, Better Conservation gives you
more work time.
3 Close the PowerBook control panel.
If you don’t use the computer for several minutes, it goes to sleep without any
action on your part. How many minutes pass before the computer goes to
sleep depends on the battery conservation setting you chose.
To put the computer to sleep before automatic sleep takes effect, choose Sleep
from the Special menu or use the Sleep Now module in the Control Strip.
To wake the computer from sleep, press any key (except Caps Lock).
Automatic sleep does not take effect under the following circumstances:
m AppleTalk is turned on in the Chooser and the power adapter is plugged in.
m Your computer is connected to a shared disk on the network.
m Your computer’s printer port is in use.
m Your computer’s internal modem is in use.
