P400 Touch screen brightness won't adjust

First off, I see this seems to be a problem across all of your computers and has been for years... why isn't there a fix?


I used my brightness down button once and now it won't go back up. I can't adjust the settings at all, despite the graphic on the screen showing me the meter going up and down. I've checked all drivers, tried uninstalling and reinstalling lenovo energy management, and I've still got nothing. I've stopped short of a factory reset because that's super annoying having set everything up and then a couple weeks after purchase have to do it again. Any other alternatives first?
