Is there an app that I can download to give me more power options for running on battery? What I would like to be able to do is set a screen brightness and volume level for running off battery and AC adapter. So when I unplug the power cord the volume will automatically mute and the screen brightness will drop to say 3, like wise when the power cord is plugged in the volume will automatically change to 10 and the brightness will go to full.
