Power Management Setup - MSI P55A-G55 series Manual

Power Management Setup

Important
S3-related functions described in this section are available only when the BIOS sup-
ports S3 sleep mode.
▶ ACPI Function
This item is used to activate the ACPI (Advanced Configuration and Power Manage-
ment Interface) Function. If your operating system is ACPI-aware, such as Windows
98SE/ 2000/ ME/ XP, select [Enabled].
▶ ACPI Standby State
This item specifies the power saving modes for ACPI function. If your operating system
supports ACPI, such as Windows 2000/ XP, you can choose to enter the Standby mode
in S1(POS) or S3(STR) fashion through the setting of this field. Settings are:
[S1] The S1 sleep mode is a low power state. In this state, no system
context is lost (CPU or chipset) and hardware maintains all sys-
tem's context.
[S3] 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 compo-
nents turn off to save energy. The information stored in memory will
be used to restore the system when a "wake up" event occurs.
▶ EuP 2013
This item is used to reduce the power consumption in ACPI S5 state.
