（1） ACPI Suspend Type:
This item specifies the power saving modes for ACPI function. Available
options are:
S1 (POS):
The S1 state is low power state. In this state, no system context (CPU or
Chipset) is lost and the hardware maintains all system contexts.
S3 (STR):
The S3 state is a lower power state, where the information of system
configuration and opened applications / files are saved to main memory.
The remaining power of other hardware components are turn off to save
energy.
The information stored in memory will be used to restore the system when a
[wake up] event occurs.
S1 & S3
If S3 state is supported by the system, by default [S3] is automatically
selected. Otherwise [S1] is selected.
（2） Power Management:
Power management allows the computer to save electricity when it is not in
use by entering increasingly deep power saving modes.
（3） Video Off Method:
This function serves as both a screen saver and power saver for monitors.
See the next function, Video Off After, for setting the video timer.
Blank Screen - BIOS will only blank the monitor's screen. The electricity
saved in this mode is negligible and this function is only used as a screen saver
to prevent screen damage while the screen is on but not in use.
V/H SYNC+Blank - The system turns off the vertical and horizontal
synchronization ports, writes blanks to the VGA buffer and the monitor's
electron gun turns off. This function requires a monitor with Green features in
order to take advantage of the power saving function. If you enable this function
and do not have a Green monitor, the result will be the same as if you had
selected Blank. This function serves as both a screen saver and a power saver.
DPMS Support - Select this option if your video card supports the Display
Power Management Signaling (DPMS) standard (i.e., you have a monitor that
supports Green features). Use software supplied by your video subsystem to
set video power management options.
（4） HDD Power Down:
Shuts down any IDE hard disk drives in the system after a period of inactivity
as set in this user configurable field. This feature does not affect SCSI hard
drives.
