2. Keyboard power (3-pin KBPWR)
This jumper allows you to enable or disable the keyboard wake-up
feature. Set this jumper to pins 2-3 (+5VSB) to wake up the computer
when you press a key on the keyboard (the default is the Space Bar).
This feature requires an ATX power supply that can supply at least
500 mA on the +5VSB lead, and a corresponding setting in the BIOS.

3. USB device wake-up (3-pin USBPW1-4, USBPW5-8)
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 and S4 sleep modes (no power to CPU, DRAM in slow refresh,
power supply in reduced power mode).
The USBPW1-4 jumper is for the rear USB ports (USB port 1-4). The
USBPW5-8 jumper is for the internal USB connectors (USB port 5-8)
that you can connect to additional USB ports.
