I started using my macbook pro with an external monitor in mirror mode...but I can't seem to unplug the power when I'm in this state...it automatically goes to sleep. I want to be able to unplug my laptop when its fully charged since its recommended to do so to preserve the battery life...but it doesn't seem like I can when using it this way. Any tips? Or is it really not that big of a deal to unplug your battery every time it's fully charged. Are Apply batteries doomed to poop out eventually no matter what? I suppose turning it off at the end of work day could recoup damage? Help!
