Slow Blinking LED for Suspend State Indicator
When the CPU goes into a suspend state, the power LED will start blinking to
indicate that the CPU is in suspend mode. When the user presses any key, the
CPU will wake-up and the LED will automatically stop blinking and remain on.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, the USB keyboard will
work like a normal keyboard during system boot-up.
Real-Time Clock Wake-up Alarm
Although the PC may be perceived to be off when not in use, it is still capable
of responding to preset wake-up events. In the BIOS, the user can set a timer
to wake-up the system at a predetermined time (see page 5-14).
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system
suspend button. When the user depresses the power button, the system will
enter a SoftOff state. The monitor will be suspended, and the hard drive will spin
down. Depressing the power button again will cause the whole system to wake-
up. During the SoftOff state, the ATX power supply provides power to keep the
required circuitry in the system alive. In case the system malfunctions and you
want to turn off the power, just depress and hold the power button for 4 seconds.
The power will turn off and no power will be provided to the motherboard.
External Modem Ring-on
Wake-up events can be triggered by a device such as the external modem ringing
when the system is in 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 defined as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, updates and asset
tracking can occur after hours and on weekends so daily LAN traffic is kept to
a minimum and users are not interrupted.
The motherboards have a 3-pin header (WOL) used to connect to the 3-pin header
on a Network Interface Card (NIC) that has WOL capability. Note that Wake-On-
Lan can only be used with an ATX 2.01 (or above) compliant power supply.
