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:

1In Workgroup Manager, click Preferences.

2Make 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.

3Select one or more computers or computer groups.

4Click Energy Saver and then click Desktop.

5From the OS pop-up menu, choose Mac OS X or Mac OS X Server and set the management setting to Always.

6To adjust sleep settings, choose Sleep from the Settings pop-up menu and do the following:
