Introduction
X6DHT-G User's Manual
In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an oper-
ating system-independent interface for configuration control. ACPI lever-
ages the Plug and Play BIOS data structures while providing a processor
architecture-independent implementation that is compatible with the Win-
dows 2000, Windows 2003 and Windows Vista Operating Systems.
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 suspend mode. When the user presses
any key, the CPU will wake-up and the LED will automatically stop blinking
and remain on.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a
system suspend button to make the system enter a SoftOff state. The moni-
tor will be suspended and the hard drive will spin down. Pressing 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 Press and hold the power button for 4 seconds.
This option can be set in the Power section of the BIOS Setup routine.
External Modem Ring-On
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 defined as the ability of a management application to re-
motely 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 traffic 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
