The Adaptive Brightness setting in Windows 10 is a useful setting you can use in adjusting your computer’s brightness. It helps you get the brightness automatically based on the light around your computer. However, there are times when it does not work or it doesn’t turn off when you want it to. If this issue happened right after you update or install Windows 10, then read on as this post will give you a couple of options you can try to resolve the problem.
Option 1 – Try to run the Power Troubleshooter
The first thing you can do to resolve the issue with Adaptive Brightness is to run the Power Troubleshooter as the problem could occur due to some conflicted power settings. To use it, refer to the following steps:
- Open the Windows 10 Settings panel and go to Update & Security and then to Troubleshoot.
- After that, scroll down to your left-hand side and click the Power option.
- From there, you should see the “Run the troubleshooter” button. Click on it to fix the problem.
- Afterward, follow the next on-screen instructions that follow.
Option 2 – Try disabling or turning off the corresponding options in GPU settings
The problem might be due to the Graphics card settings. If you are using either an AMD graphics card or the HD graphics of Intel, you may have to disable the power-related options in the GPU settings. To be specific, you have to disable the Vari-Bright in AMD graphics card settings or the Display Power Saving Technology under Intel’s Graphics panel.
- AMD users:
- Open the AMD Radeon settings panel.
- Then go to Preferences. From there, select Radeon Additional Settings.
- Next, go to the Power tab and click the PowerPlay option.
- You should find an option called “Enable Vari-Bright” located on your right-hand side. Remove the mark from its checkbox and then save the changes you’ve made.
- Intel users:
- Open the Intel Graphics and Media Control Panel from your Desktop.
- Then select the Basic mode and go to the Power tab.
- From there, select “On battery” as Power Source and then you’ll get the Display Power Saving Technology option. It should be set to enabled by default.
- Now remove the mark from the checkbox and then save the changes you’ve made.
Option 3 – Try resetting the Power Plan defaults
You might also want to use a command-line tool to resolve the problem. This command-line tool is known as PowerCfg. It is a command utility tool that will scan your computer for 60 seconds to know its power. This tool gives detailed results in the form of an HTML report that will help you in evaluating the real cause of the battery drain issues. You can also use this tool to reset the Power Plan defaults of your computer. To use it, follow the steps below.
- Open the Command Prompt as administrator.
- Then type in the following command and tap Enter to execute it:
powercfg –restoredefaultschemes
- After the command has been executed, restart your computer.
Option 4 – Try updating your Graphics drivers
- First, boot your computer into Safe Mode.
- After that, tap the Win + R keys to launch Run.
- Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
- After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
- After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
- Now restart your computer.
- After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.
Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.
Option 5 – Try disabling adaptive brightness via Registry Editor
Since you will be dealing with Registry files in this post, you need to create a System Restore point first. Once you have that covered, proceed to the following steps:
- Tap the Win + R keys to open the Run dialog box.
- Next, type “regedit” in the field and hit Enter to open the Registry Editor.
- After that, navigate to this path: HKEY_LOCAL_MACHINESOFTWAREIntelDisplayigfxcuiprofilesMediaBrighten Movie
- Now double click on the “ProcAmpBrightness” and set its value to “0”.
- Now go to this path: HKEY_LOCAL_MACHINESOFTWAREIntelDisplayigfxcuiprofilesMediaDarken Movie
- From there, double click on “ProcAmpBrightness” and set the value to “0”.
- Then close the Registry Editor and restart your PC and then see if the problem’s fixed or not.
