Hardware Configuration
Enable/Disable USB Wakeup Jumper: JPUSB1
Use the JPUSB1 jumper to wake up your system by pressing a key on a USB keyboard or
clicking the USB mouse. Use the JPUSB1 jumper together with the USB wakeup feature in the
BIOS. Enable this jumper and the USB feature in the BIOS to wake up your system via USB
devices.
Note
When the USB function is enabled in the BIOS, and the USB wakeup jumper
is disabled, remove the USB devices from the USB ports whose USB jumper is
disabled before the system goes into the standby mode.

Enable/Disable Factory Test Jumper: JPT1
Clear CMOS Jumper: JBT1
Caution
Always remove the AC power cord from the system before clearing
CMOS.
Caution
For an ATX power supply, you must completely shut down the system,
remove the AC power cord, and then short JBT1 to clear CMOS. Do not use the
PW_ON connector to clear CMOS.
Use JBT1 to clear CMOS. Instead of pins, this “jumper” consists of contact pads to prevent
accidental CMOS clearing. To clear CMOS, use a metal object such as a small screwdriver to
touch both pads at the same time to short the connection.
