1.9Jumpers
This section describes and illustrates the jumpers on the motherboard.
1.USB deviceSet 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
The USBPWR_12 and USBPWR_34 jumpers are for the rear USB port. USBPWR_56 is for the internal USB header that you can connect to the front USB ports.
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.
The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode.
