Using power saving modes 
In addition to the normal operating mode, which allows you to turn off specific devices, your computer has two distinct
power saving modes: Standby and Hibernate. Use the Standby and Hibernate power saving modes to override a profile
setting or initiate an immediate action. 
Standby — Saves the state of the system and peripheral devices in memory (RAM). Power consumption is reduced
to a minimum. The system remains on, and the computer screen (LCD) is off. 
Hibernate — Saves the state of the system and peripheral devices to the hard disk. Power consumption is reduced
to the lowest possible setting without being completely off. Hibernate mode consumes the lowest level of power.
Your computer enters Hibernate mode when the remaining battery charge drops below 5 percent, regardless of the
setting you select. 
  
 Some software programs and peripheral devices prevent the system from entering Hibernate mode. If you are using a
program that prevents the system from entering Hibernate mode, save your data frequently to avoid data loss. 
To activate Standby mode 
1.
Press the key combination Fn+Esc. The power indicator blinks in this mode. 
2.
Press any key to return to Normal mode. 
To activate Hibernate mode 
1.
Press the key combination Fn+F12 or the power button and release it immediately. Do not move the computer
until the power indicator turns off. 
2.
Press the power button to return to normal mode. 
  
 If the computer does not activate Hibernate mode, see 
 for more information.
