Fix: Windows Brightness Control Missing in Laptop

Some users have complained that the Windows brightness setting is missing from their PC, which is a frustrating problem as most users adjust the brightness of their laptop screen while working, watching a movie, etc. In this post, we will share how to fix the issue behind the Windows brightness control missing in Laptop.

Note: Before we go ahead, let’s get one thing clear. If you use an external monitor with a laptop, the brightness controls will not work or will be missing. When the Laptop screen is active, you should see the brightness control. Using the hardware button or OEM software to manage the monitor’s display would be best.

Possible Reasons for Brightness Control To Be Missing in Laptop

The taskbar and the Notification Center frequently undergo design changes in new versions of Windows, but the brightness slider should still be accessible there. Given below are the possible reason why the brightness slider could go missing on Windows:

  • Disabled monitor driver in Device Manager: It prevents Windows from using more recent drivers, which do not support this technique of adjusting brightness.
  • Old graphics drivers: Using obsolete or out-of-date graphics card drivers can cause instability while adjusting the brightness, so installing the most recent drivers as soon as possible is advised.
  • Notification Center no longer has brightness settings: It is possible that something or someone disabled this option, and all you have to do to enable it again in Settings.

3] Enable Display Control Panel via Group Policy

Windows Registry is a database where Windows and other applications store their configuration and settings. As a matter of fact, whatever changes are made via Group Policy are also reflected in Registry.

It’s a critical database, so we recommend creating a system restore point before making any changes. In case of any unforeseen event, you should be able to restore it.

  • Open Registry Editor (Type regedit in the Run prompt, and press the Enter key).
  • In the Registry Editor window, navigate to the following path:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
  • Find the NoDispCPL value in the right pane, and then double-click it.
  • Enter 0 under Value data, then click OK.

Close the Registry Editor, restart your PC, and check if the issue is resolved.

5] Install & Update Display Driver (Through OEM Software)

Maintaining your drivers updated is crucial to avoid any compatibility problems that could prevent your PC from functioning correctly. If your missing brightness slider is caused by a damaged or out-of-date driver, upgrading it should solve the issue.
