1-24 Chapter 1: Product introduction
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 1A on the +5VSB lead, and a
corresponding setting in the BIOS.
3. USB device wake-up (3-pin USBPW12, USBPW34, USBPW56,
USBPW78)
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 USBPWR12 and USBPWR34 jumpers are for the rear USB ports. The
USBPWR56 and USBPWR78 jumper is for the internal USB connectors that
you can connect to additional USB ports.
