Novell LINUX ENTERPRISE DESKTOP 10 SP2 - GNOME 08-05-2008 Manual page 107

There are several sleep modes or actions you can set in the Power Management module:
Do nothing
The computer does not shut down or automatically go into any kind of power-
saving mode. If you have a laptop, the laptop continues to run normally when the
lid is closed.
Blank screen
The screen is blanked, reducing power consumption.
Suspend
Suspend mode turns off power-consuming computer components such as the display
and the hard drive without saving the contents of RAM. Any unsaved data is lost.
Hibernate
The computer saves the contents of RAM to the hard disk, then shuts down. When
you turn the computer on again, the saved data is put back into RAM, restoring
your computer to the state it was in before it shut off. Hibernate requires an amount
of free hard disk space equal to the amount of RAM installed on the computer.
To open the Power Management module, click Computer > Control Center > System
> Power Management.
Procedure 2.6 Specifying Your Computer's Sleep Settings
1 Click the tab for the type of power you are using: if your computer uses AC
power, click Running on AC. If your computer runs on battery power, click
Running on Battery. If your computer operates on both AC and battery power,
you can configure the settings on both tabs.
The settings you choose are in effect no matter which power source you use.
2 Use the sliders to set the amount of inactive time that passes before the display
and computer go into sleep mode.
When the display is in sleep mode, the computer continues to run. When the
computer is in sleep mode, power to the display and hard disk is shut off and the
computer uses only the power needed to maintain the contents of RAM.
3 If the computer is a laptop, set the actions you want taken when the laptop lid is
closed.
