2. 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 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.
