							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.
