Wake-On-USB Keyboard
This function allows you to use a USB keyboard to wake up a
system from the S3 (STR - Suspend To RAM) state. Refer to “USB
KB Wake-Up From S3” in the Power Management Setup section in
chapter 3 for more information.
Important:
•
If you are using the Wake-On-USB Keyboard function for 2
USB ports, the 5VSB power source of your power supply
must support
≥
1.5A.
•
If you are using the Wake-On-USB Keyboard function for 3
or more USB ports, the 5VSB power source of your power
supply must support
≥
2A.
RTC Timer to Power-on the System
The RTC installed on the system board allows your system to
automatically power-on on the set date and time. Refer to “Resume
By Alarm” (“Wake-Up Event Setup” field) in the Power Management
Setup section in chapter 3 for more information.
ACPI STR
The system board is designed to meet the ACPI (Advanced
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
®
98SE/2000/ME/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
®
98SE/2000/ME/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 storing all programs and data files during the entire
operating session into RAM (Random Access Memor y) when it
powers-off. The operating session will resume exactly where you left
off the next time you power-on the system.
