2. USB device wake-up (3-pin PS2_USBPW)

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 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.
