2.  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.
The USBPW1-4 jumpers are for the rear USB ports. The USBPW5-8 and 

USBPW9-12 jumpers are for the internal USB connectors that you can 

connect to additional USB ports.

•  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 will not power up.

•  The total current consumed must NOT exceed the power supply  

capability (+5VSB) whether under normal condition or in sleep mode.
