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 USBPWR12 and USBPWR34 jumpers are for the rear USB ports.

The USBPWR56 and USBPWR78 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 would not power up.

• The total current consumed must NOT exceed the power supply

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