ACPI Suspend Type (S3 (STR))

Use this item to define how your system suspends. In the default, S3, the suspend mode

is a suspend to RAM, i.e, the system shuts down with the exception of a refresh current

to the system memory.

Resume By RING (Disabled)

An input signal on the serial Ring Indicator (RI) line (in other words, an incoming call

on the modem) awakens the system from a soft off state.

Resume By PCI/PCI-E/Lan PME (Disabled)

These items specify whether the system will be awakened from power saving modes

when activity or input signal of the specified hardware peripheral or component is

detected.

Resume By PS2 KB (S3) (Disabled)

This item enables or disables you to allow keyboard activity to awaken the system

from power saving mode.

Resume By PS2 MS (S3) (Disabled)

This item enables or disables you to allow mouse activity to awaken the system from

power saving mode.

Resume on RTC Alarm

The system can be turned off with a software command. If you enable this item, the

system can automatically resume at a fixed time based on the system’s RTC (realtime

clock). Use the items below this one to set the date and time of the wake-up alarm. You

must use an ATX power supply in order to use this feature.

Resume By USB (S3) (Disabled)

This item allows you to enable/disable the USB device wakeup function from S3 mode.
