6 Managing power Your computer can operate on either battery power or external power. When the computer is running on battery power and an external power source is not available to charge the battery, it is important to monitor and conserve the battery charge. Some power management features described in this chapter may not be available on your computer. Using Sleep and Hibernation CAUTION: Several well-known vulnerabilities exist when a computer is in the Sleep state. To prevent an unauthorized user from accessing data on your computer, even encrypted data, HP recommends that you always initiate Hibernation instead of Sleep anytime the computer will be out of your physical possession. This practice is particularly important when you travel with your computer. 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. 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 your work very quickly. You can also initiate Sleep manually. For more information, see Initiating and exiting Sleep on page 29. ● Hibernation-The Hibernation state is automatically initiated if the battery reaches a critical level or the computer has been in the Sleep state for an extended period of time. In the Hibernation state, your work is saved to a hibernation file and the computer powers down. You can also initiate Hibernation manually. For more information, see Initiating and exiting Hibernation (select products only) on page 30. Initiating and exiting Sleep You can initiate Sleep in any of the following ways: ● Select the Start button, select the Power icon, and then select Sleep. ● Close the display (select products only). ● Press the Sleep hot key (select products only); for example, fn+f1or fn+f12. ● Briefly press the power button (select products only).

battery power and an external power source is not available to charge the battery, it is important to monitor
and conserve the battery charge.
Some power management features described in this chapter may not be available on your computer.
Using Sleep and Hibernation

Several well-known vulnerabilities exist when a computer is in the Sleep state. To prevent an
unauthorized user from accessing data on your computer, even encrypted data, HP recommends that you
always initiate Hibernation instead of Sleep anytime the computer will be out of your physical possession.
This practice is particularly important when you travel with your computer.
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.
