4. USB device wake-up (3-pin USBV1, USBV2, USBV3) 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 USBV1 jumper is for the rear USB ports. The USBV2 and USBV3 jumpers are for the internal USB headers. 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.
