2. USB device wake-up (3-pin USBPW12, USBPW34)

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 USB device wake-up feature requires a power supply that can provide

500mA on the +5VSB lead for each USB port. Otherwise, the system would

not power up.

• The total current consumed must NOT exceed the power supply capability

(+5VSB) whether under normal condition or in sleep mode.

3. 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.
