What year machine is it? Should be able to flip down the cover on the bottom of the monitor and scroll through settings to adjust it. That's probably only in a D or newer though. I dont think its adjustable in the older ones.

I've never been able to find anything in the A or B models that changes the brightness. If you find it let the rest of us know.
