5. Keyboard power (3-pin J1)
This jumper allows you to enable or disable the keyboard wake-up
feature. Set this jumper to pins 2-3 (+5VSB) if you wish to wake up the
computer when you press a key on the keyboard. This feature requires
an ATX power supply that can supply at least 1A on the +5VSB lead,
and a corresponding setting in the BIOS.
6. USB device wake-up (J28, J29, J20)
Set these jumpers to +5V to wake up the computer from S1 sleep
mode (CPU stopped, DRAM refreshed, system running in low power
mode) using the connected USB devices. Set to +5VSB to wake up
from S3 sleep mode (no power to CPU, DRAM in slow refresh, power
supply in reduced power mode).
The J28 and the J29 jumpers are for the rear USB ports. The J20 is
for the internal USB header that you can connect to the front USB
ports.
