Hi, same problem here. No battery icon and no trackpad settings available. Plus the webcam stoped working too. I have a MacBook Pro late 2011, this happened between me changing the optical drive for an ssd and updating from Yosemite to High Sierra. So it could be a hardware problem or maybe the update. I will try to solve it coming back to Yosemite.
