Power Management Setup - MSI Mega 180 User Manual

4.7 Power management setup

Sleep 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,
you can choose to enter the Standby mode in S1(POS) or S3(STR) fashion through
the setting of this field. Options are:
Auto
S1/POS
S3/STR
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 in
formation 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.
