Yup -- You can also do this if you are plugged in and want to adjust the brightness. Like if you are in the dark completely and the screen is like blinding you. The reason it dims is a default setting on your computer to preserve the battery life when you're not plugged in. Also by default, they assume that if you are plugged in you'd want the screen fully lighted. Of course, people have different preferences, and FN + arrows is a very easy way to adjust the screen dimness/brightness.
Also, if it's annoying you constantly, you could probably just go to Control Panel > Power Settings and manually change it so that every time it behaves the way you want it to. But quickly looking at the laptop I'm using right now (which is a dell 5100) I don't see an immediate way to do this. Anyone else?
