2. USB device wake-up (3-pin PS2_USB_PWR)

Set this jumper 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 mode

(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.
