Introduction

This function allows you to use the PS/2 key-
board or PS/2 mouse to power-on the sys-

tem.

Important:
The 5V_standby power source of your power supply must sup-
port

≥720mA.

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) specifi-

cation. 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. 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

without having to go through the

sometimes tiresome process of closing files, applications and operat-
ing system. This is because the system is capable of storing all pro-
grams 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.
