Power Management —Power Saving Modes

Standby

All devices are powered up and in suspend mode

except for the CPU clock.

Hibernate

Suspend to Disk is similar to turning off the computer,

except that the current state of the computer is copied

to the hard disk as a special file. When the computer

returns from suspend mode, the desktop appears

with the same files and programs open as when the

computer was suspended. Suspend to Disk 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. This

mode is also called hibernation mode.

Suspend-to-disk Partition/Suspend-to-disk File

In order to Suspend to Disk, you must have a special

suspend-to-disk partition/file on your hard disk drive.

This partition is pre-installed on your computer. The

pre-installed partition is large enough to store all

system memory.

Power Off

System is shutdown.

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.
