Unable to change your laptop screen brightness? The brightness keys doesn’t work and the brightness slider doesn’t change anything. That’s a known issue and there are multiple fixes for this issue.

First of all, the problem can take place when you 1. Do a clean windows 10 install 2. Install a wrong graphic driver (software).

  1. When you installed Windows recently.

When you installs Windows, you won’t be able to use Bluetooth, Change brightness, play HD videos and other depends on your hardware. Windows 10 have generic drivers for these component, for like WiFi will work right after you install Windows 10 on a HP ENVY 13 laptop, but the same won’t work on laptop running on Intel cherry trail CPU. You see my point is that Windows 10 does support majority of hardware but at basic level. To take full advantage you must install the driver specific to that hardware.

If your computer or laptop based on Intel HD graphics, be assured that Windows update will install the drivers automatically (as soon as you have internet connection). You can see this computer is running on Intel HD graphics 620, so When I install Windows the brightness control simply fails to change brightness. This is because the graphic driver is missing. You may also face performance lag (while opening start menu, playing videos) this can be easily fixed once you install the appropriate graphics driver on your computer.

To fix this, Open Automatic Updates and let it download and install available updates. Available updates are consist of Feature update, security patches and Driver updates. If you are data-Nazi, use this Microsoft tool to prevent specific updates from being download. Then only driver updates will be installed.

Once done, or if you don’t know, click the view installed update history and see if there is something related to graphics or display.

As in the below screenshot you can see “Intel Corporation — display update” under. This ensures that Windows installed the graphic driver, and you can now change your screen brightness. This will also fix the Night light.

If you computer has different sets of Drivers, Windows might won’t be able to provide you drivers. In that case, you have few options.

  1. Force Windows to check graphics driver and download: From the Device manager you can command Window to specifically look for graphic driver and download/install it. You can open device Manager, by right-click on the MY PC icon choosing Manage button.

2. Manually Download and install your Graphic driver.

Dell, lenovo, HP, Asus and other provide drivers for their products.You can visit their support website, look up for updates using your product model, (ie. HP envy AD128TU). You’ll see all drivers for your computer, look for graphics driver, download it on your computer. Extract if it’s a archive file and open the setup and follow on screen instruction to install it. All the functions should work fine including changing (increasing and decreasing) brightness.

HP ships laptop with all the drivers on your computer, you can access the folder and look for graphic drive and manually install the driver.


However, Windows made is super easy to automatically downlad and install graphic driver,but if you’re having issues follow these steps and see if it hepls.

Turn off Driver signature enforcemet.

To install 3rd party graphics driver you’ll have to command windows to skip driver signature check. Because developers have to pay Microsoft to get certificate.
