Wake-On-USB Keyboard
The Wake-On-USB Keyboard function allows you to use a USB
keyboard to wake up a system that is in the S3 (STR - Suspend To
RAM) state. Refer to Jumper Settings for Wake-On-USB Keyboard
in chapter 2 and 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 4
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
On Alarm 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
®
98/2000/ME 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
®
98/2000/ME 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. Refer to Using the Suspend to RAM
Function in appendix A for more information.
