2. USB device wake-up (3-pin USBPW1-4, USBPW5-8, USBPW910)

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.
The USBPW1-4 jumpers are for the rear USB ports. The USBPW5-8 and

USBPW910 jumpers are for the internal USB connectors that you can

connect to additional USB ports.

• 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 will 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 500 mA on the +5VSB lead, and a

corresponding setting in the BIOS.
