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.
