If the room is too bright it won't turn on. At least that's how it works for me. I think you have to change it to not automatically adjust brightness to be able to play with it at all times.

I don't know about late mbps but on mine it will only let you adjust the keyboard backlight when it is dark enough for you to need it. Try covering your speaker grills then trying to adjust (if that is where the light sensor is)
