How do you turn your screen light on brighter on a Dell laptop screen?

Q: When i turned on my computer it was the way it normally was, with the normal screen light. But my screen got darker, and i can only see the icons and stuff when my room light is on. How can I make my screen bright again?? HELP!!!

A: FN key + Up Arrow = Increase Brightness FN key + Down Arrow = Decrease Brightness also remember that in the power management option you can set your display to be as dim as you want if you are on batteries to save you battery time, or as bright as possible when you are hooked up the power supply P.S the FN key is located on the bottom left side of the keyboard right next to the control key.
