BIOS Setup
Suspen d mode
This item specifies the power saving modes for ACPI function. If your
operating system supports ACPI, 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 hard-
ware maintains all system context.
[S3 (STR)]
The S3 sleep mode is a lower power state where the
information of system configuration and open appli-
cations/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.

This setting allows the activity of the USB device to wake up the system
from S3/S4 sleep state.
