Initiating Sleep or Hibernation

Microsoft® Windows® has two power-saving states, Sleep and Hibernation.

NOTE: The Rapid Start Technology feature allows your computer to resume quickly from inactivity. Rapid Start Technology manages your power-saving options as follows:

●Sleep – Rapid Start Technology allows you to select the Sleep state. To exit from Sleep, press any key, activate the TouchPad/Imagepad, or press the power button briefly.

●Hibernation - Rapid Start Technology controls Hibernation management and initiates Hibernation automatically under the following conditions:

◦After 2 hours of inactivity when running on battery or external power

◦When the remaining battery charge reaches a critical level

After Hibernation is initiated, press the power button to resume your work.

Because Hibernation is controlled by Rapid Start Technology, Hibernation does not display as an option.

NOTE: Rapid Start Technology is enabled at the factory and can be disabled in Setup Utility (BIOS). If Rapid Start Technology is disabled in Setup Utility (BIOS), Hibernation options are available to be actively selected.

In the Sleep state, the screen clears, and your work is saved to memory, letting you exit Sleep faster than exiting Hibernation. If the computer is in the Sleep state for an extended period or if the battery reaches a critical battery level while in the Sleep state, the computer initiates Hibernation.

In the Hibernation state, your work is saved to a hibernation file on the hard drive and the computer turns off.

CAUTION: To reduce the risk of possible audio and video degradation, loss of audio or video playback functionality, or loss of information, do not initiate Sleep or Hibernation while reading from or writing to a disc using an optional external optical drive (purchased separately) or an external media card.

NOTE: You cannot initiate any type of networking connection or perform any computer functions while the computer is in the Sleep state or in Hibernation.

Initiating and exiting Sleep

The system is set at the factory to initiate Sleep after a period of inactivity when running on battery power or on external power.

Power settings and timeouts can be changed using Power Options in Windows Control Panel.

With the computer on, you can initiate Sleep in any of the following ways:

●Briefly press the power button.

●Close the display.

●Select Start, click the arrow next to the Shut down button, and then click Sleep.
