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
The USBPWR01 jumper is for the rear USB ports. The USBPWR23 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 1A 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.
