Initiating Sleep or Hibernation
Microsoft® Windows® has two power-saving states, Sleep and Hibernation.
NOTE:
Intel Rapid Start Technology (RST) is enabled at the factory. Intel RST only allows the Sleep
state to be actively selected (unless RST is disabled in Setup Utility (BIOS)). However, Hibernation is
initiated after a period of inactivity when running on battery power or on external power, or when the
battery reaches a critical battery level.
In the Sleep state, the screen clears, and 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.
In the Hibernation state (when Intel RST is disabled in Setup Utility (BIOS)), 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, if Intel RST is
disabled) while reading from or writing to a disc using an optional external optical drive (purchased
separately) 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.
●
Select
Start
, click the arrow next to the Shut down 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 the computer returns to the screen
where you stopped working.
NOTE:
If you have set a password to be required on wakeup, you must enter your Windows
password before the computer will return to the screen.
