Little more info. Sorry, it's not related to lid closing. It's related to power status changing. (which tends to happen in correlation with lid operations). Every time I attach or remove the power plug the screen jumps to 100% brightness. This would almost even make sense if it only happened when plugging in, but in what world do I want the screen to jump from 20% to 100% when I *remove* power?
