Power Management —Error! Style not defined.
Hibernate
Hibernate is similar to turning off the computer,
except that the current state of the computer is copied
to the hard disk. When the computer returns from
hibernation mode, the desktop appears with the same
files and programs open prior to your computer
entering hibernation mode. Hibernate is very useful
when you don't want to take the time to shut down all
open programs one by one to shut off the computer,
only to have to open the same programs and files the
next time you use the computer.
Power Off
System is powered off.
Initiating Suspend Mode
There are four ways to initiate suspend mode. The settings can be adjusted in the
Power Management dialog box:
• The computer will automatically enter suspend mode when not used for a set
period of time.
• Selecting the Stand by button in the Shut Down Windows dialog box.
• Closing the screen cover (assuming no external monitor has been connected).
• Pressing the power button (if enabled in power settings).
• Pressing the suspend function key <Fn> + <F4>.
Using the BIOS Utility for Power Management
With Windows running in ACPI mode, power can be controlled through the Power
Management dialog box only. With operating systems that use ACPI power
management, BIOS power settings have no effect.
Power Button Settings
The function of the power button can be set to Shutdown or Standby in the Power
Management Properties dialog box in the Windows Control Panel. However, holding
the power button down for more than four seconds will force a power off while
operating under any situation, resulting in the loss of any unsaved information.
