How to Fix Lenovo Keyboard Backlight Not Working on Windows 11


A backlit keyboard is a great feature that provides convenience and comfort when typing in low-light conditions. However, some users may encounter issues with their Lenovo laptops, where the keyboard backlight stops working after updating to Windows 11. In this comprehensive guide, we’ll walk you through the troubleshooting steps to fix the Lenovo keyboard backlight not working issue on Windows 11. By following these steps, you can regain control of your keyboard backlight and enjoy a seamless typing experience.

1. Toggle Keyboard Backlight Using the Hotkey

The first step is to check if the keyboard backlight can be enabled or disabled using the hotkey combination. This combination varies depending on the Lenovo laptop model. Typically, you can try pressing “Fn + Spacebar” or “Fn + F5/F6” keys to enable the backlighting. If your laptop has a dedicated backlight switch, try toggling it a few times.

2. Increase the Keyboard Brightness

In some cases, the keyboard backlight may be on but set to a low brightness level, making it difficult to notice. Locate the key with the illumination icon on the keyboard’s top row or function keys. Press this key in combination with the “Fn” key to cycle through different brightness levels until the backlight becomes visible.

3. Check Settings in the Lenovo Vantage App

Lenovo laptops often come with the Lenovo Vantage app, which allows users to manage various laptop settings, including keyboard backlight customization. Launch the Lenovo Vantage app and navigate to the keyboard settings. Ensure that the keyboard backlight option is enabled, and adjust the timeout settings if necessary.

4. Run the Windows Keyboard Troubleshooter

Windows 11 includes a built-in troubleshooter that can identify and resolve common keyboard-related issues. To run the troubleshooter, follow these steps:

  • Open the Start menu and click the gear icon to launch the Settings app.
  • Navigate to the “System” tab and scroll down to select “Troubleshoot.”
  • Go to “Other troubleshooters” and click the “Run” button next to “Keyboard.”
  • Follow the on-screen instructions to run the troubleshooter and check if the keyboard backlight starts working.

5. Update Keyboard Drivers

Outdated or corrupted keyboard drivers can cause keyboard backlight malfunctions. To update the keyboard drivers, follow these steps:

  • Click on the Search icon on the taskbar, type “Device Manager,” and select the first result that appears.
  • Expand the “Keyboards” category, right-click on your keyboard, and select “Update driver” from the context menu.
  • Follow the on-screen prompts to search for and install the latest driver updates.

6. Check If Keyboard Backlight Works in Safe Mode

To determine if third-party software is causing the issue, boot Windows 11 into Safe Mode and check if the keyboard backlight works. Here’s how to do it:

  • Press the Windows key + R to open the Run dialog. Type “msconfig” in the box and press Enter.
  • Under the “Boot” tab, tick the “Safe boot” option and click “Apply” followed by “OK.”
  • Save your work and select “Restart” to boot Windows into Safe Mode.
  • Check if the keyboard backlight works in Safe Mode. If it does, it indicates that a third-party app or service may be causing the problem.
