The power LED on the VL-CBR-5013/5014 indicates that the paddle board is being powered by
the 5V supply (though it does not indicate that all S0 power supplies are good). The LED is lit
only when the board is in the S0 power state. If the board enters a Sleep or Hibernate mode, the
LED will not be lit.
