Initiating Sleep and Hibernation

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

●Sleep–The Sleep state is automatically initiated after a period of inactivity. Your work is saved to memory, allowing you to resume working very quickly. You can also initiate Sleep manually. For more information, see Manually initiating and exiting Sleep on page 25.

●Hibernation–The Hibernation state is automatically initiated if the computer is in the Sleep state for an extended period. Hibernation puts your open documents and programs on your hard drive, and then turns off your computer.

NOTE: You can manually initiate Hibernation. See Manually initiating and exiting Sleep on page 25 and Manually initiating and exiting Hibernation on page 26.

CAUTION: To reduce the risk of possible audio and video degradation, loss of audio or video playback, or loss of information, do not initiate Sleep while reading from or writing to a disc or an external media card.

NOTE: You cannot connect to a network or perform any computer functions while the computer is in the Sleep state or in Hibernation.

Intel Rapid Start Technology (select models only)

For select models, the Intel Rapid Start Technology (RST) feature is enabled by default. Rapid Start Technology 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, or briefly press the power button.

●Hibernation—Rapid Start Technology initiates Hibernation after a period of computer inactivity while the computer is in the Sleep or when the battery reaches a critical level. After Hibernation is initiated, press the power button to resume your work.

NOTE: Rapid Start Technology can be disabled in Setup Utility (BIOS). If you want to be able to initiate Hibernation yourself, you must enable user-initiated Hibernation using Power Options. See Manually initiating and exiting Hibernation on page 26.
