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 Microsoft® 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 29. ● 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 in Windows Control Panel. For more information, see Enabling and exiting user-initiated Hibernation on page 30. 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. 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 list opens, click Settings, click the Power icon, and then click Sleep.
