Potential Causes for Adaptive Brightness Issues

1. Issues Stemming from Windows Updates:

Windows routinely receives updates from Microsoft. Sometimes, these updates might clash with the Adaptive Brightness functionality. If this feature starts malfunctioning after an update, consider reverting to an older Windows version or installing the most recent one.

2. Corrupted Registry Files:

Windows registry, a vital part of the OS, can cause various system features, including Adaptive Brightness, to misbehave if its components get damaged. Addressing these registry issues might resolve Adaptive Brightness problems.

3. Graphics Driver Conflicts:

The graphics driver plays a crucial role in the Adaptive Brightness feature. A driver that’s outdated, not compatible, or corrupted can inhibit the system’s ability to sense ambient light changes. In such cases, updating or reinstalling the driver can be the answer.

4. Power Plan Discrepancies:

Windows comes with several power plans, dictating the system’s energy use. Incorrect settings in these plans can make the system bypass Adaptive Brightness. Tweaking these settings or setting up a new plan can often rectify the issue.

Fix 6: Repairing Corrupted System Files with “SFC” Command

Here’s how you can utilize Command Prompt to mend these corrupted files:

Launching the Command Prompt with Elevated Rights:

• Navigate to the Start menu, search for “Command Prompt” or “cmd”.
• Right-click on the result and select “Run as administrator”.
• Run the System File Checker (SFC).
• In the Command Prompt window, type the following command:
  sfc /scannow

• Press Enter and allow the process to complete. This will check for any corrupted system files and attempt to repair them.
• Restart Your Computer: Once the SFC scan is complete, restart your computer to implement any potential fixes.
• Utilizing Deployment Image Service and Management Tool (DISM) if SFC Fails: If the SFC tool encounters errors it cannot fix, you can use the DISM commands to potentially address the issues:
• In the Command Prompt with administrative privileges, input the following commands sequentially, hitting Enter after each:
• DISM /Online /Cleanup-Image /CheckHealth
• DISM /Online /Cleanup-Image /ScanHealth
• DISM /Online /Cleanup-Image /RestoreHealth

These commands will check the system’s health, scan for any corruptions, and then restore the system’s health by fixing those corruptions. After running these commands, it’s recommended to run the sfc /scannow command once more to ensure all corruptions have been addressed.
