2. 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 these jumpers to +5VSB to wake up the
compurer from S3 and S4 sleep modes (no power to CPU, DRAM in slow
refresh, power supply in reduced power mode).
3. Keyboard power (3-pin KBPWR)
This jumper allows you to enable or disable the keyboard wake-up feature.
When you set this jumper to pins 2-3 (+5VSB), you can wake up the
computer by pressing a key on the keyboard (the default is the Space Bar).
This feature requires an ATX power supply that can supply at least 1A on the
+5VSB lead, and a corresponding setting in the BIOS.
