Hi, I am trying to strengthen the light on my backlit keyboard, but when I try to increase it just shows the icon with the circle with the line going through it, and it doens't do anything. Fix?
I too was confused by this. It seems that with the mbp you can only turn on the key light when the ambient light is dim ( which was not the case with the MBA I had for few days): the last poster is right. Get in the dark to enjoy your key light.
There's 4 white LED's under the keyboard...
and two light sensors, one on e each side, where the grills are. If you look carefully (at the photo) you can just see the top of the clear dust cover...
