Keyboard backlighting is a popular feature in modern laptops and desktop keyboards, providing better visibility in low-light environments and adding an aesthetic appeal to your workspace. However, it’s not uncommon to experience issues with keyboard lighting, whether it’s not turning on, flickering, or behaving erratically. The good news is that these issues are usually easy to resolve. In this article, we’ll walk you through a comprehensive guide on how to fix keyboard lighting issues on any model.
1. Check the Keyboard Backlighting Settings
Before jumping into troubleshooting, the first step is to check your keyboard’s lighting settings. On many keyboards, especially on laptops, the backlight can be toggled on and off or adjusted through software or hardware settings.
For Windows Laptops:
- Adjusting Brightness: Many Windows laptops allow you to adjust keyboard brightness via function keys (e.g., F3/F4, F5/F6). Look for a small icon that looks like a keyboard with a light or the sun symbol. Press these keys to increase or decrease the backlight brightness.
- Check Keyboard Settings: Some laptops come with software that controls keyboard settings, such as Lenovo Vantage for Lenovo laptops, Alienware Command Center for Alienware systems, or Razer Synapse for Razer keyboards. Open the software, look for keyboard settings, and ensure the backlighting is enabled and set to your desired brightness.
For macOS Laptops:
- Using the Function Keys: On MacBooks, you can use the F5 (decrease) and F6 (increase) keys to adjust the keyboard backlighting. If your MacBook has a Touch Bar, you may need to adjust the backlighting via the Control Center.
- System Preferences: Go to System Preferences > Keyboard, then check the option “Adjust keyboard brightness in low light”. Ensure that the option is enabled if you want the backlight to adjust automatically in low-light environments.
2. Restart Your Computer
Sometimes, a simple restart can fix keyboard lighting issues. If the keyboard backlight is not responding despite checking settings, restarting your device will reset hardware and software connections, possibly resolving any glitches.
3. Check for Keyboard Shortcuts
Certain keyboards have dedicated shortcuts for controlling backlighting. These shortcuts vary based on the manufacturer and model of your keyboard. Here are a few common examples:
- HP Laptops: Use the F5 key to adjust the keyboard backlight.
- Dell Laptops: Use the F10 or F6 key to increase or decrease brightness.
- Corsair Keyboards: For external keyboards like Corsair, use FN + F4 to toggle the lights on/off or adjust brightness.
- Logitech Keyboards: For Logitech external keyboards, the FN + F8/F9/F10 keys are typically used to adjust backlighting.
Make sure you’re using the correct keyboard shortcut to adjust the lighting on your specific device.
4. Update Keyboard Drivers
If your keyboard lighting is still not working, it could be due to outdated or corrupted keyboard drivers. These drivers allow your operating system to communicate with the keyboard and control features like backlighting. Here’s how to update the drivers:
For Windows:
- Press Windows + X and select Device Manager.
- Scroll down and expand the Keyboards section.
- Right-click your keyboard driver and select Update driver.
- Choose Search automatically for updated driver software. Windows will check for newer drivers and install them if available.
If there is no update, you can try uninstalling the keyboard driver (right-click > Uninstall device) and restarting your computer. Windows will automatically reinstall the necessary driver upon reboot.
For macOS:
macOS usually handles drivers automatically, but you can try updating macOS to the latest version via System Preferences > Software Update. This will ensure that any updates to hardware drivers, including the keyboard, are installed.
5. Check for Physical Damage
Physical issues, such as spills, dirt, or damage to the keyboard, can cause the backlight to malfunction. Here’s what you can do:
- Clean Your Keyboard: Dust, dirt, or food particles can obstruct the backlight. Use a can of compressed air to gently clean the keyboard, particularly around the keys.
- Check for Liquid Damage: If you’ve spilled any liquids on your keyboard, the backlight may stop working. In this case, turn off the device, disconnect the keyboard (if external), and let it dry for at least 24 hours before trying to use it again. If liquid damage is severe, professional repair may be required.
6. Reinstall the Keyboard Software (If Applicable)
For keyboards that rely on specialized software to control backlighting, like mechanical gaming keyboards, reinstalling the software may help fix lighting issues.
- Uninstall the keyboard software through your computer’s Control Panel (Windows) or Applications folder (macOS).
- Download the latest version of the software from the manufacturer’s website (e.g., Razer Synapse, Corsair iCUE, SteelSeries Engine).
- Reinstall the software and check if the backlighting now works.
7. Check for Hardware Failures
If none of the above steps resolve the issue, there may be a hardware failure, particularly if the keyboard has been in use for an extended period. This could involve a malfunctioning backlight bulb or the keyboard’s internal wiring. In this case:
- For Laptops: If your laptop keyboard backlight is not working and you have already ruled out software and settings, it could be a hardware issue that needs professional repair. Contact the manufacturer or an authorized service center.
- For External Keyboards: If you are using a mechanical or external keyboard, the issue might lie with the keyboard’s hardware itself. Check the manufacturer’s warranty for potential replacement options.
8. Contact Manufacturer Support
If you’ve followed all the steps above and the backlight still isn’t working, the issue might be deeper than a simple fix. In this case, it’s time to contact customer support. Most manufacturers offer troubleshooting tips, and if the device is under warranty, they might even offer to repair or replace the faulty keyboard.

For external keyboards, check for any warranty or repair options. For laptops, contacting the manufacturer or a professional repair service is the best option.
6. How do I clean my keyboard to fix the lighting?
Dirt, dust, or spills can obstruct the keyboard’s backlighting. Use compressed air to blow away debris from between the keys. If there’s sticky residue, gently wipe the keyboard with a soft cloth. For more thorough cleaning, disconnect the keyboard (if external), turn it off, and use a slightly dampened cloth to clean the surface.
7. Can my laptop keyboard backlight be turned on or off automatically?
