The keyboard backlight feature is preinstalled on most Lenovo products. If your Lenovo keyboard backlight doesn’t work properly, we have some fixes for you! Read on and find out how to get the backlight back on your Lenovo keyboard.

5 fixes for Lenovo keyboard backlight not working

1: Use hotkeys to enable backlight

2: Restart your PC

3: Set up your keyboard backlight via Lenovo Vantage

4: Perform a power drain

5: Check if backlight works in BIOS

Before we dive into the solutions, you should verify if your keyboard supports the backlight feature. All Lenovo keyboards with the backlight feature will have a little light-bulb icon on Esc key, Space key or Fn key. If you don’t see any, it means your keyboard doesn’t come with the backlight feature.

Fix 1: Use hotkeys to enable backlight

Lenovo keyboard backlight can be brought up by hotkeys.

To enable backlight: press Fn key and Space key or Esc key.

You can also hold down Fn key and tap Space key to adjust the brightness level. The three levels are off, low (dim), high (bright).

If the hotkeys don’t work, move on to the next solution.

Fix 2: Restart your PC

Another simple but worth-trying solution to get your keyboard backlight is to restart your PC. This should work when the issue isn’t hardware-related, but with programs that were running and interfering with your keyboard’s function.

If this fix doesn’t give you luck, try the next one.

Fix 3: Set up your keyboard backlight via Lenovo Vantage

Lenovo Vantage is a tool that allows users to customize their PC or any Lenovo product. You can set up your keyboard backlight via this app:

  1. Download Lenovo Vantage.
  2. Install and run the program.
  3. Under Device > Input & accessories, you’ll be able to find your keyboard information and adjust backlight.
Users have been reporting minor issues with Lenovo Vantage. If you already have Lenovo Vantage but the keyboard backlight isn’t on, try to uninstall or update it in Microsoft store and test the issue.

If this doesn’t help, proceed to the next solution.

Fix 4: Perform a power drain

Though less likely, performing a power drain could help solve keyboard backlight issues when the system is interfering with your keyboard’s function. The ways of performing a power drain vary depending on your battery type:

If your battery is built in your PC:

  1. Unplug the AC adapter, and hold down the power button for at least 10 seconds.
  2. Plug the AC adapter back into your PC, then turn on your PC.

If you battery is removable from your PC:

  1. Release the battery from your PC and unplug the AC adapter. If you’re not sure how to safely remove your battery, please refer to your manufacturer’s manual.
  2. Hold down the power button for at least 10 seconds.
  3. Put your battery back and plug in the AC adapter. Then try to turn on your PC.

After restarting your PC, test if the backlight on your keyboard works. If this doesn’t does the trick, try the last solution.

Fix 5: Check if backlight works in BIOS

Your keyboard itself could be somehow faulty, causing the backlight not working issue. To rule out the possibility of hardware damage, you can test it in BIOS.

  1. Restart your PC. When the Lenovo logo appears on your screen, hold down F1 key or tap Enter key repeatedly on your keyboard.
  2. You should enter BIOS now. Below is how a BIOS menu screen would typically look like, but the screens could differ on different models.
  3. Press Fn key and Esc key or Space key to test it your keyboard backlight works.
  4. If your backlight is on, then you would need to update your BIOS. Lenovo has provided a BIOS update package that directly tackles the keyboard backlight issue. Unfortunately, it’s only for a couple of Lenovo Legion products with Windows 10 64-bit, including:

    Legion 5-15IMH05 

    Legion 5-15IMH05H

    Legion 5P-15IMH05

    Legion 5P-15IMH05H

    Legion 5-17IMH05

    Legion 5-17IMH05H

    If you don’t see your model from the list above, contact Lenovo for support.
  5. If your backlight doesn’t work in BIOS, then it means there could be something wrong with your keyboard. Consider taking your keyboard to Lenovo service center, or you can contact Lenovo online for support.
