PCI Express PM Function, Continued
ACPI Suspend Type
This item specifies the power saving modes for ACPI function. If your operating system supports ACPI,
such as Windows 98SE, Windows ME and Windows 2000, you can choose to enter the Standby mode in
S1 (POS) or S3 (STR) fashion through the setting of this field.
Options are:
➢
[S1 (POS)] The S1 sleep mode is a low power state. In this state, no system context is lost (CPU
or chipset) and hardware maintains all system contexts.
➢
[S3 (STR)] The S3 sleep mode is a lower power state where the information of system
configuration and open applications/files is saved to main memory that remains powered while
most other hardware components turn off to save energy. The information stored in memory will
be used to restore the system when a “wake up” event occurs.
Power Management
This option allows you to select the type (or degree) of power saving for Doze, Standby, and Suspend
modes. The table below describes each power management mode:
Max Saving
Provides maximum power savings, only available for
SL CPUs. The inactivity period is 1 minute in each
mode.
User Define
Allows user to set each mode. Select time-out periods
in the PM Timers section.
Min Saving
Provides minimum power savings. The inactivity
period is 1 hour in each mode (except the hard drive).
Disabled
(Default) Provides no power saving features.
Video Off Method
This setting determines the manner in which the monitor is blanked.
V/H SYNC+Blank
It turns OFF vertical and horizontal synchronization
ports and writes blanks to the video buffer.
DPMS
Select this option if your monitor supports the Display
Power Management Signaling (DPMS) standard of the
Video Electronics Standards Association (VESA). Use
the supplied software for your video subsystem to
select video power management values.
Blank Screen
The System only writes blanks to the video buffer.
