3. USB device wake-up (3-pin USBPWR_12, USBPWR_34,
USBPWR_56)
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 sleep mode (no power to CPU, DRAM in slow refresh, power
supply in reduced power mode). Both jumpers are set to pins 1-2 (+5V)
by default because not all computers have the appropriate power
supply to support this feature.
The USBPWR_12 and USBPWR_34 jumpers are for the rear USB
ports. The USBPWR_56 jumper is for the internal USB header that you
can connect to the front USB ports.
1. This feature requires a power supply that can provide at least 2A
on the +5VSB lead when these jumpers are set to +5VSB.
Otherwise, the system does not power up.
2. The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep
mode.
