178 Chapter 10 Managing Preferences
The table below summarizes what you can control with settings in each Energy Saver
pane.
Using Sleep and Wake Settings for Desktop Computers
Putting a computer to sleep saves energy because it turns off the display and stops the
hard disk from running. Waking up from sleep is faster than starting up your computer.
You can use the Energy Saver preference settings to put computers to sleep after a
specified period of inactivity. Other settings enable you to wake or restart the
computer when certain events happen.
To set sleep and wake settings:
1 In Workgroup Manager, click Preferences.
2 Make sure the correct directory is selected and you are authenticated.
To switch directories, click the globe icon. If you are not authenticated, click the lock
and enter the name and password of a directory domain administrator.
3 Select one or more computers or computer groups.
4 Click Energy Saver and then click Desktop.
5 From the OS pop-up menu, choose Mac OS X or Mac OS X Server and set the
management setting to Always.
6 To adjust sleep settings, choose Sleep from the Settings pop-up menu and do the
following:
