Power-saving modes
There are several modes that you can use at any time to conserve power. This section introduces each
mode and gives tips on the effective use of the battery power.

display, do as follows:

• Sleep (standby in Windows XP). In sleep (standby) mode, your work is saved to memory, and then the
hard disk drive or the solid state drive and the computer display are turned off. When your computer
wakes up, your work is restored within seconds. To put your computer into sleep (standby) mode, press
Fn+F4. To return from sleep (standby) mode, press Fn key.
