Not all Lenovo laptops come with a backlight keyboard. Look for a little bulb icon on the Space, Esc, or Fn keys to confirm if your laptop has one. If you don’t see it, your laptop isn’t equipped with a backlit keyboard.
The instructions in this guide applies to all models of Lenovo laptops such as Lenovo ThinkPad, Legion, Carbon, and ThinkBook.
If your laptop has a backlit keyboard but isn’t working, begin troubleshooting by increasing the backlight brightness level.
This is because the keyboard backlight may be off because its brightness is set to a minimum. To increase the brightness level, press the Function Key (Fn) and the backlight shortcut key.
If the issue persists, try these troubleshooting steps in the order as I have explained:
You may not have to try all of them; follow them until you find a solution that works for you.
1. Update Drivers
The issue might be due to outdated or corrupted keyboard drivers, which can be fixed by updating them. Here’s how to do that:
- Open Device Manager.
- Expand the Keyboard section.
- Right-click on your keyboard and select Update driver from the menu.
2. Restart your Laptop
Restarting a PC is a well-known and proven method to fix random errors. If this keyboard backlight issue is due to temporary bugs or glitches, rebooting your laptop would likely solve it.
If this does not work, move on to the next solution.
3. Use Lenovo Vantage
Lenovo Vantage is a freeware utility from Lenovo that allows users to customize many aspects of their PCs. It also supports controlling of the keyboard backlight.
Here’s how to use it:
- Download Lenovo Vantage and install it on your computer.
- Once installed, open it on your computer and go to Devices -> Input & accessories.
- Select Keyboard. There you will see option to adjust your keyboard backlight
4. Power Drain your Laptop
Lastly, if none of the above methods worked for you, you should power drain your Lenovo laptop.
Power drain is a helpful practice that clears the laptop cache memory. It’s not as complicated as it might seem. Here’s how to do that:
Shut down your laptop and unplug it from the charger.
If your laptop has a removable battery, remove the battery and hold the power button for 15 seconds.
If your laptop has a non-removable battery, do not shut it down from the settings. Instead, press and hold the power button while the computer is On and hold it for 15 seconds.
