When you are working in low-light environments you can turn on the backlit function on the keyboard. This helps you get your work done comfortably but, on a few occasions, the function may fail to respond or work weirdly. If your backlit keyboard is not working on your Windows desktop or laptop, please read this post.
Many keyboards have an option of a backlit keyboard where a backlight switches ON after a certain time of the day or when the surroundings are dark. This allows the user to work even at night. However, at times the backlit keyboard doesn’t turn ON.
Backlit keyboard not working in Windows 11/10
If you have Windows 11/10 installed on your PC and all your hotkeys work fine except the backlit keyboard, you can try the following methods. There’s no need to buy a USB snake light that lights up only one area.
- Check if your keyboard supports the backlight option
- Check if there’s a switch to enable the backlit keyboard
- Adjust the brightness level
- Check Backlit timeout settings
- Run the Keyboard troubleshooter
- Update Keyboard drivers
- Perform Clean Boot
- Enter BIOS Setup Utility
Let’s cover the above methods in a bit of detail.
1] Check if your keyboard supports the backlight option
While buying a keyboard, many users assume it must have a backlight system since most modern keyboards do. However, that isn’t the case. Even with high-end modern computers, the laptop may or may not have a backlit keyboard.
So, please sort this part out with your system manufacturer. However, if the backlight has worked with your system previously and the issue is recent, then proceed with the following solutions.
2] Check if there’s a switch to enable the backlit keyboard
A lot of laptops have a system in which the backlit keyboard needs to be fired up using a combination of keys. Check if you can turn the keyboard lights on or off using the keys.
The keyboard backlight has three modes: Off, Low, High.
In some keyboards, the combination is Fn+F4. In some it is Fn+F5. On some laptops, to turn on or off the backlight, you have to press Fn + Spacebar on the keyboard. Please confirm the combination with your system manufacturer.
3] Adjust the Brightness level
If the backlit function is not working, chances are you might have set the brightness to an extremely low level. To adjust the brightness of the backlight, press the key with the backlight icon two or three times in a row. The keyboard backlight dims and brightens. You might need to press the Fn (function) key at the same time to activate the backlight key.
If you are using a Lenovo computer or PC, open Lenovo Vantage. For Windows 10, Lenovo Settings has been replaced with Lenovo Vantage. It offers an easy-to-use interface to one easy-to-use interface to Personalize your settings, run device diagnostics, and more.
Open Lenovo Vantage.
From the left panel of the homepage, look for the keyboard backlight icon.
When found, tap or click to change it.
4] Check Backlit timeout settings
If the backlight stays on for only a few seconds, the backlight timeout settings might need configuring in the BIOS.
5] Run the Keyboard troubleshooter
The Keyboard troubleshooter is an excellent tool to diagnose issues related to the keyboard and resolve them if possible. The procedure to run the Keyboard troubleshooter is as follows:
- Right-click on the Start button and select Settings from the menu.
- In the Settings window, go to the System tab in the left pane.
- In the right pane, scroll down and select Troubleshoot.
- In the Troubleshoot window, select Other troubleshooters.
- Scroll down to the Keyboard troubleshooter and click on Run corresponding to it.
The Keyboard troubleshooter will diagnose problems with the backlit keyboard and resolve them if possible.
6] Update Keyboard drivers
In case your keyboard is sensor-based and the drivers are obsolete, it might not work since it wouldn’t be able to detect when the light goes off. In such a case, you could use the Intel Driver and Support Assistant to update the system’s drivers.
7] Perform Clean Boot
In case a third-party software is causing the problem with your keyboard, the best way to isolate this cause would be to perform a Clean Boot on your system. By doing so, any third-party program influencing the keyboard would not launch automatically at startup. Later, you can isolate the software through hit and trial.
8] Enter the BIOS set up utility
Firstly, make sure the computer has the latest System Setup (BIOS) and is configured correctly.
- Enter the BIOS setup or BIOS Setup Utility
- Use the arrow keys to navigate to the System Configuration tab.
- Under it, locate Action Keys Mode. Make sure to enable this mode if it is not enabled already.
On some BIOS, you will see it somewhere under System Configuration > Click Keyboard Illumination. The options may be:
- Disabled or Off – The keyboard illumination is off.
- Dim – The keyboard illumination is at half brightness.
- Bright – The keyboard illumination is at full brightness.
You might want to also make sure that your BIOS is updated to the latest version.
How to check if your computer has a backlit keyboard?
This can be confirmed by looking at your keyboard physically or by contacting your seller. The reason is that even keyboards in the most modern high-end laptops might not have a backlit keyboard. This usually happens to adjust other features into the design.
What is the use of the Fn key in the keyboard?
The Fn key is used to use the additional functions with the F1 to F12 keys. The output of these functions can vary depending on the brand of the computer. While this key wasn’t as common in earlier versions of keyboards, it is the norm as of now.
Hope this helps.
