3.USB device wake-up (3-pin USBPW12, USBPW34, USBPW56) 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 and S4 sleep modes (no power to CPU, DRAM in slow refresh, power supply in reduced power mode).

•The USB device wake-up feature requires a power supply that can

provide 500mA on the +5VSB lead for each USB port. Otherwise, the system would not power up.

•The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode.
