Lighting, brightness

Whenever I play through my built scene as I reach I specific area within that scene my screen brightness increases and saturates some of my terrain textures. It only occurs when I walk near a particular bright terrain. Also this seems to only occur when my laptop is not plugged into power, when it is plugged in the terrain has no saturation. Is there a setting within unity that I am missing here that would correct this issue? Thanks.

I doubt it’s a setting in Unity, instead you might want to look at your laptop’s PowerSave scheme and see if it automatically fools around with brightness/contrast/etc when it’s not plugged in.
