1-5 Power Confi guration Settings
This section describes the features of Power Confi guration and Power Management
of your motherboard.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in the suspend mode. When the user presses any key, the
CPU will "wake-up" and the LED will automatically stop blinking and is turned on.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, it will function like a normal
keyboard during system boot-up.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system
suspend button. When the user presses the power button, the system will enter
a SoftOff state. The monitor will be suspended and the hard drive will spin down.
Press the power button again to "wake-up" the whole system. During the SoftOff
state, the ATX power supply provides power to the required circuitry and keep the
system "alive." In case the system malfunctions and you want to turn off the power,
just press and hold the power button for 4 seconds. The power will turn off and no
power will be provided to the motherboard.
Wake-On-Ring (WOR)
Wake-up events can be triggered by a device such as the external modem ringing
when the system is in the SoftOff state. Note that external modem ring-on can only
be used with an ATX 2.01 (or above) compliant power supply.
Wake-On-LAN (WOL)
Wake-On-LAN is defi ned as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and asset
tracking can occur after hours and on weekends so that daily LAN traffi c is kept
to a minimum and users are not interrupted. The motherboard has a 3-pin header
(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has
WOL capability. In addition, an onboard LAN controller can also support WOL
without any connection to the WOL header. The 3-pin WOL header is to be used
with a LAN add-on card only.
*Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power supply.
