Hi, Just wanted clarification about the ambient light sensor for the keyboard... I just purchase a MBP 15" C2D a week ago and noticed that when the keyboard is lit up, there's no glow around the spacebar. I know that there is no lettering on the spacebar button itself to illuminate, but why is there no glow underneath? If I'm eye-level with the keyboard, all the keys have light showing underneath, except the spacebar. I hope this is normal. Please clarify that your MacBook Pros share the same characteristics.
