Why laptop brightness button is not working after windows 10 update?

Before going to the solution, we like everybody to know the reason behind this issue. The one and only one reason for this brightness issue is due to the missing of related software drivers. Almost all of the latest Intel processors have on board graphics and corresponding graphics drivers which will get trashed during the system update. When you are performing a system update from windows 8 or 8.1 to windows 10, you are wiping out all of the system drivers and programs. This make difficulty in detecting the graphics hardware after you open up brand new windows 10.

So to make the brightness button working on windows 10, you need to download and install the corresponding drivers. If you are a beginner to windows platform, you may face difficulty in installing the same. So we are giving two easy way to get back the brightness button working in windows 10. Check out how to get the drivers.

Solution 1 – Brightness issue fixing using built in device manager

In this first method, we are showing you how to fix the brightness button issue without using any third party tools. We highly recommend this way to solve the above problem. Here we are using the windows built in software named Device manager which keep tracks all of the drivers and hardware components in your PC. Every-time you connect a hardware to your PC, device manager will list out it and it will show whether the corresponding drivers are missing or not.

In our case, we have an built in graphics hardware component which provides the graphics related function to our PC. But the drivers will be not there as we just migrated to windows 10. So we need to download and install the drivers first. For installing drivers using device manager, follow the steps below.

Step 1: Press the start button and search for “device manager”.
