2. USB device wake-up (3-pin USBPW1234, USBPW34,

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 (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.
