Some users have reported that Windows 11’s display brightness automatically increases and decreases.
So, if you are using a Windows 11 laptop and facing the same problem, here’s what you can do to resolve this problem.
Please note that the methods we have shared also work on Windows 10 and other older versions of Windows. That means you can follow the same methods to fix brightness not control not working problem on every Windows version.
1. Restart your Windows 11 PC
The first thing you should do to resolve the Windows 11 Brightness Control Not Working issue is to restart the PC.
Restarting Windows 11 will possibly remove the bugs & glitches that may be preventing the brightness control from working.
So, open the Windows 11 Start Menu and click the Power Option. On the Power Option, select Restart.
2. Adjust the Display Brightness from the Action Center
If you use the keyboard shortcut to adjust the brightness, but it’s not working, you can try changing the display brightness from the Action Center.
To open the Action Center on Windows 11, press the Windows + A button. When the Action Center opens, you can adjust the brightness by moving the slider to the left or right.
3. Make Sure Your Device Has Enough Battery
When a Windows 11 device runs low on battery, it dims the screen’s brightness to preserve the remaining battery life.
So, if your device is low on battery power, the brightness slider will likely not work because you are not allowed to adjust the brightness.
However, that restriction can be lifted by disabling Windows 11’s Power Saver mode through Settings. Otherwise, you can recharge your device to regain brightness.
4. Update the Display Driver
Display Driver is the first you should update if the brightness control is not working on your Windows 11 computer. Sometimes, the brightness control doesn’t work due to an outdated or buggy display driver.
So, before trying anything else, make sure to update the Display Driver of your PC to fix the Windows 11 brightness control, which is not working. Here are easy steps to update the Display Driver.

2. On the Device Manager, expand the Display Adapters option as shown below.
3. Now, right-click on your GPU or display adapter that powers your display and select the Update Driver option.
4. On the next Window, click on the Search automatically for the updated driver software option as shown below.
Now, Windows 11 will automatically search for available updates and install them on your device if it finds one.
5. Use Microsoft’s Basic Display Adapter
Many users have reported fixing the Windows 11 brightness control not working issue by switching to Microsoft’s Basic Display Adapter. If Windows 11 is incompatible with your display driver, you won’t be able to control the brightness. Here’s how to use Microsoft’s Basic Display Adapter on Windows 11.

If the above methods have failed to fix the Brightness issue on Windows 11, you need to run the SFC Command. Brightness control not working or users unable to adjust the display brightness are often a result of system file corruption.
The SFC or system file checker tool will find and fix corrupted system files and probably fix every brightness-related problem on your PC. Here’s what you need to do.
- First, open the Windows 11 search and type in Command Prompt. Next, right-click on the CMD and select Run as administrator.
- Type in sfc /scannow on the Command prompt and hit Enter.
- Wait until Windows 11 completes the scan. Once the scan is finished, close the command prompt and restart your PC.
This is how you can run the SFC command on Windows 11 to fix the brightness control that doesn’t work.

To update Windows 11, navigate to Settings > Windows Update > Check for Updates. This will launch the Windows 11 update tool and will update your operating system.
