Keyboard and USB device wake-up (3-pin KB_USBPWB)
This jumper allows you to enable or disable the keyboard and USB port 1~4 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 or using a USB device. This feature requires an

ATX power supply that can supply at least 1A on the +5VSB lead, and a corresponding

setting in the BIOS. This jumper is for the rear USB ports.

3.

USB device wake-up (3-pin USBPWF)
Set this jumper 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.
