    Same Issue since yesterday. My old Dell XPS L501X display is on full blast since yesterday, nothing is working to change brightness. My laptop is 1st gen i5 and only from Intel HD graphics driver, I am able to reduce brightness as some have pointed out in reddit post. Please resolve this bug Microsoft

      hi,

       

      I have the same L501x model as you do. I've found out that if you disable sensor services in services.msc in Win 10 v 1709 you get the same issue as in v1803. I believe it's a sensor service issue. Since you are running v1803 can you please check if you disable and re-enable the service fix the brightness issue?

       

      Thanks,
