Benefits of Sleep Mode
The Sleep Mode feature provides the following benefits:
■ Restores the previous working environment more rapidly than does the
Hibernation Mode feature.
■ Saves power by shutting down the system when the computer receives
no input or hardware access for the time period set by the System
Sleep Mode feature.
■ Allows the use of the panel power off feature.
Executing Sleep Mode
You can enter Sleep Mode in one of three ways:
■ Click Start, point to the arrow icon ( ) and then select
Sleep from the menu.
■ Close the display panel. Please note that this feature must be enabled
within the Power Options (to access it, click Start -> Control Panel ->
System and Security -> Power Options).
■ Press the power button. Please note that this feature must be enabled
within the Power Options (to access it, click Start -> Control Panel ->
System and Security -> Power Options).
■ Before entering Sleep Mode, be sure to save your data.
■ Do not install or remove a memory module while the computer is in
Sleep Mode. The computer or the memory module could be damaged.

(unless the computer is connected to an AC power source). Data in
memory could be lost.
■ When the AC adaptor is connected, the computer will go into Sleep
Mode according to the settings in the Power Options (to access it,
Start -> Control Panel -> System and Security -> Power Options).
■ To restore the operation of the computer from Sleep Mode, press and
hold the power button or any key on the keyboard for a short amount of
time. Please note that keyboard keys can only be used if the Wake-up

■ If the computer enters Sleep Mode while a network application is
active, the application might not be restored when the computer is next
turned on and the system returns from Sleep Mode.
■ To prevent the computer from automatically entering Sleep Mode,
disable Sleep Mode within the Power Options (to access it, Start ->
Control Panel -> System and Security -> Power Options).
■ To use the Hybrid Sleep function, configure it in the Power Options.
