							6 Managing power
Your computer can operate on either battery power or external power. When the computer is only
running on battery power and an AC power source is not available to charge the battery, it is
important to monitor and conserve the battery charge. Your computer supports power plans to
manage how your computer uses and conserves power so that you can balance computer
performance with power conservation.
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 32.
●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 33.
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.
