ACPI Features

ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi ca-
tion 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.
In addition to enabling operating system-directed power management, ACPI also
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 XP, Windows Vista and Windows
2008 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.

Power Supply

As with all computer products, a stable power source is necessary for proper and
reliable operation. It is even more important for processors that have high CPU
clock rates.
The X8QB6-LF/X8QBE-LF motherboard accommodates 24-pin ATX power sup-
plies. Although most power supplies generally meet the specifi cations required
by the CPU, some are inadequate. In addition, four 12V 8-pin power connections
are also required to ensure adequate power supply to the system. Also, be sure
to use a power supply that supports the specifi cations listed in the table on Page
2-3 or 2-6.
Warning! To prevent damage to the power supply or motherboard, please
use a power supply that contains a 24-pin and at least three 8-pin power
