How to Fix the keyboard backlight not working

This manual includes detailed instructions for fixing the “keyboard backlight not working” issue for PCs running Windows 11.

Restart Your Computer

Your device could occasionally require assistance to launch all the applications and programs. When the keyboard backlight not working, restarting the device is recommended. The device will start all the programs effectively after restarting.

By opting to restart your computer, you are essentially granting it a fresh start and an opportunity to rectify any underlying glitches or conflicts that may have led to the keyboard backlight not working issue.

1. Check for Hardware Issues

Before diving into software-related fixes, it’s crucial to ensure that the problem isn’t rooted in your hardware. Start by checking if the function keys themselves are functioning correctly. Press other function keys like volume control or mute to see if they work as expected. If these keys are also unresponsive, it could indicate a hardware issue, such as a faulty keyboard or a loose connection.

To rule out hardware problems, try the following:

a. External Keyboard Test: If you’re using a laptop, connect an external keyboard to your device and check if the backlight keys on the external keyboard work. If they do, it’s likely a hardware issue with your laptop’s built-in keyboard.

b. Laptop Keyboard Inspection: If you suspect a problem with your laptop’s keyboard, carefully clean it and check for any physical damage or debris that might be obstructing the function keys.

c. Driver Updates: Ensure that your keyboard drivers are up to date by visiting the manufacturer’s website or using Windows Update.
