Huh? The light bleed where? From the edges of the keys? Onto the screen? On the ceiling?
If you saw the keys lit up in a photo, chances are it was a long exposure, exaggerating the amount of light they give off.
The keys have brightness control, like the screen.
Come on man. Backlit keyboards haven't been around very long. How did anyone ever see the keys before backlighting was available?
Relax. Buy the computer.
