Help!

I have Dell laptop which I love dearly. The problem is, when it's unplugged, the monitor goes dimmer and is incredibly difficult to use if I'm in a place with normal lighting, and impossible if I want to go outside. I know this conserves power, but it makes the laptop almost unusable as a, you know, laptop since I have to keep it plugged in if I want to use it.

There's got to be some way to set it so that the monitor stays fully-bright when you unplug it. I've been all through the settings and power windows and haven't found it yet. Help!
