4.6 Power Management Features
ACPI Standby State
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/XP, 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 context.
[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.
[Auto]
BIOS determines the best mode automatically.
