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 when running on
battery power or on external power. Your work is saved to memory, allowing you to resume your
work very quickly. You can also initiate Sleep manually. For more information, see
Initiating and
exiting Sleep on page 52 .
● Hibernation–The Hibernation state is automatically initiated if the battery reaches a critical level.
In the Hibernation state, your work is saved to a hibernation file and the computer powers down.
NOTE: If you want to initiate Hibernation manually, you must enable Hibernation using Power
Options. For more information, see Enabling and exiting user-initiated Hibernation on page 53 .
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 while reading from or writing to a
disc 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.
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 press the power button briefly.
● Hibernation—Rapid Start Technology initiates Hibernation after a period of inactivity while in the
Sleep state when running on battery power or on external power 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 the Hibernation state, you must enable user-initiated Hibernation using Power Options. See
Enabling and exiting user-initiated Hibernation on page 53 .
Initiating and exiting Sleep
With the computer on, you can initiate Sleep in any of the following ways:
● Close the display.
● From the Start screen, point to the upper-right or lower-right corner of the screen. When the
charms open, select Settings, select the Power icon, and then select Sleep.
To exit Sleep:
● Briefly press the power button.
● If the display is closed, open the display.
● Press a key on the keyboard.
● Tap or swipe the TouchPad.
