Fix keyboard backlight in Windows 10

If your keyboard light is not working, here are some possible reasons and solutions:

Ensure the feature is supported

First, you need to ensure whether your laptop has a backlit feature at all. If you previously had it enabled and can’t use it anymore, that is sufficient to know that your laptop has that feature.

Another way to check whether your laptop has the backlight feature is to look for the associated button on the keyboard itself. If you find an image like the one below on any key on the keyboard, it means that your laptop has the feature.

The image would probably be as a secondary function of the button, such as alongside the arrow key as in the image below.

Another way to check if your laptop has the keyboard backlight feature is to check for the settings in BIOS. Usually, the associated settings can be found in the following path within BIOS:

BIOS -> System Configuration -> Keyboard Illumination

If you do find this setting, it means that your laptop has the feature built-in.

Enable keyboard backlight through BIOS

Now that you know that your laptop does have that feature, you can enable it. We shall start by enabling the feature through the BIOS. Navigate to the following location by accessing BIOS on startup:

BIOS -> System Configuration -> Keyboard Illumination

You should now be able to see the settings for Keyboard Illumination on the right side. It also elaborates what each of the settings would do to the backlight, and the secondary method to manage it directly from the keyboard as well.

Run the keyboard troubleshooter on Windows 10

Thankfully, Windows 10 comes with a built-in troubleshooter that scans the selected item and informs the user if any necessary actions need to be taken in order to fix an issue.

  1. Navigate to the following location:
    Start Menu -> Settings -> Update and security -> Troubleshoot -> Additional troubleshooters
  2. Now click on Keyboard and then click Run the troubleshooter.
    run the troubleshooter 1
  3. The troubleshooter will now be executed. Wait for it to finish and perform any action recommended.
  4. Restart the computer.

If you are still unable to get your keyboard’s backlight to turn on, continue to the next step.

Update Keyboard Driver

An outdated keyboard driver can also cause the backlight to not work. A simple solution is to ensure that the latest driver is installed. Follow the steps below to update your driver.

  1. Type in devmgmt.msc in Run to launch the Device Manager.
    devmgmt
  2. Expand the Keyboard and then right-click on the default keyboard. Click on Update driver from the context menu.
    update driver 1
  3. Click on Search automatically for the driver from the update wizard. Ensure that you have a live internet connection at this point.
    auto search
  4. The wizard will now search for a new driver, if available, and then install it. Reboot the computer once it is finished.

The keyboard should now be backlit. If it is still not, there is a chance that there might be a problem with the hardware. Try getting a new keyboard installed by visiting the manufacturer’s website.

You can also install and update keyboard drivers using third party software.
