It isn't supposed to be on when you're using the MBP, it only comes on as you close the lid and then pulses once it's in sleep mode.
OK, just a departure from the 2011 model I guess?? On that the light is on solid when the machine is on, pulses in sleep and is off when off (just like any other PC).
my 2006, 2008, 2010, and 2011 Macbook Pro models do not do that. They do NOT stay on when the machine is operating... and my 2012 rMBP doesn't even have a light.OK, just a departure from the 2011 model I guess??
