USB Wake-Up
Use JPUSB to enable or disable USB
Wake-Up, which allows you to wake
the system up by pressing a key on
the keyboard or by clicking the mouse
when it is connected to the USB0
or USB1 port. This jumper is used
together with the USB Wake-Up func-
tion in the BIOS. Enable both jumper
setting and the BIOS setting to allow
the system to be awakened. See the
table on the right for jumper settings.
