Fixed: Laptop brightness control is missing from Windows Control Panel.

Some users complain that there is no brightness setting on their PC, which is a frustrating problem since most users adjust the laptop screen brightness while working, watching a movie, etc. In this article, we will guide you on how to fix the Windows brightness control missing issue on your laptop.

Note: If you are using 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 slider. It is best to use a hardware button or OEM software to control the monitor’s display.

The lack of brightness control in laptops can be due to a number of factors.

The taskbar and action center often undergo changes in new versions of Windows. However, the brightness slider should still be available there. Possible reasons why the brightness slider might not be available in Windows include:

• Disabled Monitor Driver in Device Manager: This prevents Windows from using newer drivers that do not support this method of dimming.
• Old graphics drivers. Using outdated or outdated graphics card drivers may cause instability in brightness adjustment, so it is recommended to install the latest drivers as soon as possible.
• There are no more brightness settings in the Notification Center: something or someone may have disabled this option, and all you have to do is turn it back on in the settings.
