Had been able to dim out of the box, now it seems to be stuck on full brightness. This in not just an autodim issue. Powerbar settting can be changed but don't seem to have an effect. Added Dimmer ap which says its reducing from 30 to 10 but again no noticeable dimming. On custom battery management dimming settings the current dimming bar at the very bottom has no slider if that means anything. Fairly new so I've been fooling around a lot, figure I installed something or got fed something that messed it up. Any idea how to fix?
