I dont get it: while on battery, I like to dim down my screen to 1 bar of brightness. But, for some reason, the MBA automatically dims up the screen to half. No matter if I dim the screen back down, the screen will dim up to half once again on it own?!?! WTF! Here is my energy savings configuration: http://screencast.com/t/dHFlNsWyCOo Any idea what is up?
