ACPI STR
Power failure
recovery
The system board is designed to meet the ACPI
(Advanced Configuration and Power Interface) speci-
fication. ACPI has energy saving features that enables PCs to imple-
ment Power Management and Plug-and-Play with operating systems
that suppor t OS Direct Power Management. ACPI when enabled in
the Power Management Setup will allow you to use the Suspend to
RAM function.
With the Suspend to RAM function enabled, you can power-off the
system at once by pressing the power button or selecting “Standby”
when you shut down without having to go through the sometimes
tiresome process of closing files, applications and operating system.
This is because the system is capable of storing all programs and
data files during the entire operating session into RAM (Random
Access Memory) when it powers-off. The operating session will
resume exactly where you left off the next time you power-on the
system.
Important:
The 5V_standby power source of your power supply must sup-
port
≥
720mA.
When power returns after an AC power fail-
ure, you may choose to either power-on the
system manually or let the system power-on
automatically.
