1.10 Jumpers
This section describes and illustrates the jumpers on the motherboard.
1.
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).
This feature requires a power supply that can provide at least 1A on
the +5VSB lead when these jumpers are set to +5VSB. Otherwise, the
system does not power up.
The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep mode.
