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
Initiating and exiting Sleep on page 27
.
●
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:
If you want to initiate Hibernation manually, enable this option in Control Panel. For
more information, see
Enabling and exiting user-initiated Hibernation on page 27
.
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.
