  1. My Windows 8 does not display an “Enable Adaptive Brightness” option in this menu. The software and drivers are up to date. Why do I not have this option?

        • If u r not seeing “Adaptive Brightness” then perform these steps:
          1. run -> services.msc
          2. Find “Sensor Monitoring Service”
          3. Right-click and click on “Properties”
          4. Select “disable” under “startup type” option and reboot computer.

  2. I had the same problem as Jon. I didn’t have the button in the original solution. So I attempted the solution in your last post, and I restarted my computer. It did not work. I shut it down this time. Still dimmed the screen when I was through. I checked to see if Sensor Monitoring Service was still disabled and it was.

    • If Sensor Monitoring service is disabled, then adaptive brightness should not work. You plz double check that have you selected proper brightness in your “Power Plan” settings.
