Power Settings
Basic power settings help conserve energy or enhance computer performance. You can also customize
power settings for your computer hardware. For example, you can set your computer to go to sleep after a
specified period of inactivity.
If the computer is in Sleep mode, it “wakes up,” or re-loads faster than when in Hibernate mode, but your
data is less safe. If, for example, a power outage occurs in Sleep mode, unsaved data would be lost.
Hibernate mode (select models only) puts the computer into a deeper sleep, with more energy savings. In
Hibernate mode, all peripheral power shuts down and all data is saved to your hard drive. When the
computer comes out of Hibernate mode, your previous session is restored. This process takes a little longer
than awakening from Sleep mode (but less time than if you had shut down), and is considered a safer state
for data.
You can put the computer into Sleep mode in several ways. Press the Power/Sleep button on the top right
of the computer, press the Sleep button on remote control, or press the Sleep button on the upper left of
your keyboard.

Tap the Start button, tap the arrow button next to the Shut Down button, and then select Sleep.
