Setting power options

Using power-saving states

The computer has two power-saving states that are 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 reduce the risk of 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 a period of inactivity when running on battery power or on external power.

Power settings and timeouts can be changed using Power Options in Windows Control Panel.

With the computer on, you can initiate Sleep in any of the following ways:

●Briefly press the power button.

●Close the display.

●Windows 7—Click Start, click the arrow next to the Shut down button, and then click Sleep.

– or –

Windows Vista—Click Start, click the arrow next to the Lock button, and then click Sleep.

To exit Sleep:

●Briefly press the power button.

●If the display is closed, open the display.

●Press a key on the keyboard.

●Tap or swipe the TouchPad.

When the computer exits Sleep, the power lights turn on and your work returns to the screen as it was before you stopped working.

NOTE: If you have set a password to be required on wakeup, you must enter your Windows password before your work will return to the screen.
