Timeout Settings
Timeout functions can be set up to power down computer 
components by selecting the Power Schemes tab from the power 
application in the operating system’s Control Panel. When a 
component such as the monitor, hard drive, system, or video is 
not in use, the component powers down to conserve power. The 
time out interval can be set from one minute up to several hours. 
The component will power up again when you access it or press 
any key.
Setting Standby
Standby is initiated by pressing the Fn+F4 hotkeys or 
automatically by the computer if it reaches the defined percentage 
of battery pack power remaining. When Standby is initiated, 
several subsystems will power off to conserve energy. The system 
will wake up from Standby when a key is pressed. Although the 
Standby mode maintains the information and opens the file upon 
wake-up, any unsaved information is lost if the computer is 
turned off before ending Standby.
Hibernation
Hibernation is an energy-saving feature and safeguard that saves 
information in RAM to a hibernation file on the hard drive, then 
shuts down the computer. Hibernation is initiated by the computer 
when the computer reaches the defined percentage of battery 
pack power remaining. To wake the computer from Hibernation, 
press the power button. When you resume work, the information 
returns to the screen where you left off.
The computer uses the operating system with a power 
management utility that helps you maintain and conserve power 
when the computer is running on battery power.
