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. For more information, see Initiating and exiting Sleep on page 44. 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 44. 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. Initiating Sleep and Hibernation 43 NOTE: Rapid Start Technology can be disabled in Setup Utility (BIOS).
