lmost every workspace or setup will feature a device with backlighting. The RGB movement has taken over peripherals, not to mention devices. With MacBooks releasing with ever-increasing backlighting, as well as most mainstream devices, it’s easy to see how your keyboard backlighting not working is a common occurrence.
In this blog, we’re going to be investigating the common causes of your backlighting playing up and what you can do to solve it.
Common Causes for Keyboard Backlight not Working
Let’s start with discussing some of the common causes for your keyboard backlight not working.
1. Software Issues
One of the most common reasons for a keyboard backlight not working can be your computer’s software. The keyboard illumination is typically controlled by software on your device. This software can sometimes encounter errors, or ‘glitches’ and causes your backlighting to malfunction.
The easy solution to this is to first, restart your device. Then check for updates for your device, or reinstall the device software.
2. Hardware Fault
Another possible cause can be a hardware fault. Backlighting works through individual LED lights embedded beneath the keys. Like other hardware components, these can be damaged or faulty. Either through wear and tear, or poor manufacturing.
If your device has been dropped, or the keys hit hard, this could be your reason for your keyboard backlight to be not working.
Unfortunately, if this is the case, you will need to take your device to a computer repair shop. The repairs needed for this cause will need tools and training.
Our recommendation is to pursue this after you have tried all other available fixes, even if you are suspicious this could be the cause. If your device is of poor quality, it could be a good idea to upgrade to a better device, like these options here with backlighting.
3. Power Saving Mode
A common cause for your keyboard backlight not working is a simple one. Power saving mode is present on most devices, and is surprisingly a common cause for concerns. Many laptops and devices automatically turn off the keyboard backlight after a period of inactivity or when the battery level is low to conserve power.
To check if this is the case for you, plug in your device to charge, or replace your batteries. You can also check your power settings and ensure that the ‘Turn keyboard backlight off after inactivity’ option is not enabled.
How to Fix Keyboard Backlight Issues
If the common problems haven’t solved your issue, let’s dive into some troubleshooting.
1. Check Your Keyboard Settings
Always start with the most basic step. Check your device for the specific key or combination of keys that toggle the keyboard backlight.
These keys are typically marked with an icon that represents a light or something similar. For some laptops, you might need to hold the ‘Function’ or ‘Fn’ key and then press the corresponding function key to switch on the keyboard light.
They are usually situated in the F1-F12 keys, or on the arrow keys.
2. Update Your Keyboard Drivers
A simple update of your keyboard drivers can often fix many keyboard-related issues, including your keyboard backlight not working. Outdated or corrupt drivers interfere with the functioning of your hardware, luckily, it is an easy fix.
We’ve outlined the steps for you below:
- Open Device Manager: Type ‘Device Manager’ into your computer’s search bar and click on the application.
- Open the ‘Keyboards’ section: You should see a list of all keyboard devices connected to your system.
- Right-click on your keyboard: From the dropdown menu, select ‘Update Driver’. If you’re not sure which is your device, try to find the make of your device or the device number.
- Choose ‘Search automatically for updated driver software’: Your computer will then search the internet for the latest driver software for your device.
Whenever you update drivers, always restart your device to ensure they are installed, and operating effectively.
3. Hardware Inspection
If you’re still not able to rectify your issue, it may unfortunately be a hardware issue. The issue causing your keyboard backlight to not work could be a faulty keyboard, a loose connection, or a problem with the motherboard.
In this case, follow these steps to identify if this is your problem.
To inspect your hardware:
- Check keyboard connection: Make sure your keyboard is properly connected to your computer. If you’re using an external keyboard, try to unplug it and then reconnect it.
- Try a different keyboard: If possible, connect a different keyboard to your computer. If the backlight works on the new keyboard, then the issue might be with your original keyboard.
- Seek professional help: If you’re still encountering issues, it may be best to seek professional help. Take your computer to a reputable technician or your device’s service center. They can perform a thorough hardware inspection and identify if there’s a problem with the keyboard or the motherboard.
Remember, if you’re not comfortable performing these checks yourself, always seek professional help. It’s better to be safe than sorry when dealing with hardware issues.
When to Seek Professional Help Or Replace Your Device
Recognizing when to seek professional help or replace your device is crucial for preventing further damage. If you’ve tried the available troubleshooting options and your problem is still unresolved, the next step is to seek a professional.
An important aspect to consider before taking it to a professional is the device’s warranty period. If it’s still under warranty, professional repair may be covered at no cost to you.
However, if the warranty has expired, it is worth comparing the cost of repair against the cost of a new device. Replacing, or even upgrading the device may be a more cost-effective option in the long run. Repairs never guarantee long-term reliability.
