How do I adjust brightness on my Dell Latitude D6...

Look for a key labeled "Fn" (blue lettering) on the lower left side of the keyboard

Hold the "Fn" key and then use the Up/Down arrows to adjust brightness.

If that doesn't work, reboot your laptop and get into the BIOS. There is a screen for brightness. I don't recall how it is labeled, but it's one of the last pages as you cycle through the BIOS options.
