Using power-saving states
The computer has two power-saving states enabled at the factory: Sleep and Hibernation.
When Sleep is initiated, the power lights blink and the screen clears. Your work is saved to memory,
letting you exit Sleep faster than exiting Hibernation. If the computer is in the Sleep state for an extended
period or if the battery reaches a critical battery level while in the Sleep state, the computer initiates
Hibernation.
When Hibernation is initiated, your work is saved to a hibernation file on the hard drive and the computer
turns off.
CAUTION: To prevent possible audio and video degradation, loss of audio or video playback
functionality, or loss of information, do not initiate Sleep or Hibernation 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
The system is set at the factory to initiate Sleep after 15 minutes of inactivity when running on battery
power and 30 minutes of inactivity when running on external power.
Power settings and timeouts are changed using Power Options in Windows Control Panel.
To initiate Sleep while the computer is on:
● Press the Power button.
● Close the display.
● Click Start, click the arrow next to the Shut Down button, and then click Sleep.
To exit Sleep:
● Press the Power button
● If the display is closed, open the display.
● Press a key on the keyboard or button on the remote control (select models only).
● Activate the TouchPad.
When the computer exits Sleep, the Power light illuminates, and you return to the screen where you
entered Sleep.
NOTE: If a password is required when exiting Sleep, enter your Windows password at the prompt.
