Power Management Setup
The Power Management Setup allows you to save energy of your system effectively. It will shut down
the hard disk and turn OFF video display after a period of inactivity.
ACPI Function
This item allows you to enable/disable the Advanced Configuration and Power Management
(ACPI). The function is always defaulted in the “Enabled” mode.
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.
