fewest interruptions. If you can’t plug in the computer, Better Conservation

gives you the longest work time.

3 Close the PowerBook control panel.

If you don’t use the computer for several minutes (how many depends on

which setting you choose), it goes to sleep without any action on your part. A

computer in sleep has a darkened screen and appears to be off, though it is

still using battery power at a low level if the power adapter is not plugged in.

Note that a green light flashes at the top of your computer’s display when the

computer is in sleep.

To put the computer to sleep before the automatic sleep setting takes effect,

choose Sleep from the Special menu or use the Sleep module in the Control

Strip.

To wake the computer from sleep, press any key.

Automatic sleep does not take effect under the following circumstances:

m You are using an external monitor.

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 serial port is in use.
