  I'm not familiar with this, but... how would you know the lid is
  closed? Wouldn't the computer be asleep?

  There are several situations in Mac OS X where the clamshell can be
  closed and the computer will remain wide awake, or the computer will
  remain asleep when the clamshell is opened. For example, if you have
  an external monitor plugged in and the built-in display turned off,
  then opening and closing the clamshell does not put the computer to
  sleep.
