2. USB device wake-up (3-pin USBPW12, USBPW34, USBPW56, USBPW78)
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 USBPW12 and USBPW34 jumpers are for the rear USB ports. The
USBPW56 and USBPW78 jumper is 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.
