Wake-On-USB Keyboard/Mouse
The Wake-On-USB Keyboard/Mouse function allows you to use a
USB keyboard or USB mouse to wake up a system that is in the
S3 (STR - Suspend To RAM) state.
If you are using this function with a device that is connected to the
USB 2.0 port, you need to configure 2 jumpers. Refer to Jumper
Settings for Wake-On-USB 2.0 Keyboard/Mouse in chapter 2. You
also need to enable Resume on PCI Event (IRQ/Event Activity
Detect field) in the Power Management Setup submenu of the
BIOS.
If you are using this function with a device that is connected to the
USB 1.1 port, you do not need to configure any jumpers. You only
need to enable USB Resume from S3 (IRQ/Event Activity Detect
field) in the Power Management Setup submenu of the BIOS. Refer
to chapter 3 for more information.
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.
If you are using the Wake-On-USB Keyboard/Mouse
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 mainboard allows your system to auto-
matically power-on on the set date and time. Refer to Resume On-
Alarm (IRQ/Event Activity Detect field) in the Power Management
Setup section in chapter 3 for more information.
ACPI STR
The mainboard is designed to meet the ACPI (Advanced Configura-
tion and Power Interface) specification. ACPI has energy saving fea-
tures 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/XP supports
the ACPI function. ACPI when enabled in the Power Management
Setup will allow you to use the Suspend to RAM function.
