•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.

•If you are using Windows® 2000, you need to install Service Pack 4 to wake up the system from S4 sleep mode.

•The total current consumed must NOT exceed the power supply capability

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