The following jumper settings are for your reference in case you
accidentally pull out jumper caps. DO NOT change the jumper settings

up from S1 sleep state (CPU stopped; RAM refreshed; system
running in low power mode) using the connected USB devices.
Set to +5VSB to allow wake up from S3 state (no power to CPU;
RAM in slow refresh; power supply in reduced power mode).
