The RTC installed on the system board allows your
system to automatically power-on on the set date
and time.
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 support OS Direct Power Management. Currently, only Win-
dows

2000/XP supports the ACPI function. 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 Windows

2000/XP without having to go
through the sometimes tiresome process of closing files, applications
and operating system. This is because the system is capable of stor-
ing all programs and data files during the entire operating session
into RAM (Random Access Memory) when it powers-off. The oper-
ating 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.
