    Weirdest thing happened today. I did a Bios Update related to WD15 dock today from Dell. After the update, I'm now noticing that the screen brightness keys does not allow me to change the level of brightness. When I click on the brightness up or down key, the gauge pops up on the screen showing me its current level but I can't move or change the level.

    Any ideas/suggestions?

    Are you on win 10 insider builds? I think brightness keys are broken on those right now.

    That explains it! I am indeed running Build 14986 on the Slow Ring Insider program. I'm debating whether I should switch over to the pre-release setting instead of being on the fast/slow ring. Any general thoughts?
