1. USB device wake-up (3-pin USBPW12, USBPW34, USBPW56)

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 rear panel USB ports (Ports 1 to 4) do not support device wake-up from S4

sleep mode.
