This function allows you to use a USB key-
board or USB mouse to wake up a system
from the S3 (STR - Suspend To RAM) state.
Important:
If you are using the Wake-On-USB Keyboard/Mouse function for
2 USB ports, the 5VSB power source of your power supply
must support
≥
1.5A. For 3 or more USB ports, the 5VSB
power source of your power supply must support
≥
2A.
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 (Ad-
vanced Configuration and Power Interface) specification.
ACPI has energy saving features that enables PCs to implement
Power Management and Plug-and-Play with operating systems that
support OS Direct Power Management. Currently, only Windows
® ® ® ® ®
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 5VSB power source of your power supply must support
≥
1A.
