USB device wake-up (3-pin USBPW1-4, USBPW5-8, USBPW9-12)
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.
