ACPI Features

ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi -
cation defi nes a fl exible and abstract hardware interface that provides a standard
way to integrate power management features throughout a PC system, including its
hardware, operating system and application software. This enables the system to
automatically turn on and off peripherals such as CD-ROMs, network cards, hard
disk drives and printers. This also includes consumer devices connected to the PC
such as VCRs, TVs, telephones and stereos.
In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an operating
system-independent interface for confi guration control. ACPI leverages the Plug
and Play BIOS data structures while providing a processor architecture-independent
implementation that is compatible with Windows 2000, Windows XP and Windows
2003 Server.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED and LE1 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 monitor 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.
