Power Management Setup

ACPI Standby State
This item specifies the power saving modes for ACPI function. Options are:
[S1/POS]
[S3/STR]
Re-Call VGA BIOS from S3
When ACPI Standby State is set to [S3/STR], users can select the options in this field.
Selecting [Yes] allows BIOS to call VGABIOS to initialize the VGA card when system
wakes up (resumes) from S3 sleep state. The system resume time is shortened when
you disable the function, but system will need an AGP driver to initialize the VGA card.
Therefore, if the AGP driver of the card does not support the initialization feature, the
display may work abnormally or not function after resuming from S3. Options: [Auto],
[Yes], [No].
Power Button Function
This feature allows users to configure the Power Button function. Setting options:
[Power Off]
[Suspend]
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 context.
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.
The power button functions as a normal power-on/-off
button.
When you press the power button, the computer enters
the suspend/sleep mode, but if the button is pressed for
more than four seconds, the computer is turned off.
