www.makeuseof.com Function Keys Not Working in Windows 10? Here's What to Do

The Function keys give you a faster and easier way to control several hardware features. Using the Fn keys you can adjust the screen brightness, control the speaker volume, or turn on and off airplane mode, among many functions.

But sometimes these stop working and now you have to open Action Center or Settings every time you need to adjust your computer settings. If this happened to you, our guide will help you fix it.

1. Make Sure Fn Keys Are Not Locked

Most of the time, the Fn keys stopped working because someone accidentally pressed the Fn lock key. The Fn lock key also impacts other toggle keys such as Caps Lock or Num Lock so it’s easy to find out if the Fn keys are locked.

On your keyboard, look for an Fn, F lock, or F Mode key. Depending on your laptop, you should press for one time or press and hold for a few seconds. If this didn’t work, press the Fn and Esc keys at the same time.

Then, try to use one of the Function keys.

2. Check Your Keyboard

If certain Fn keys are still working, it might be a sign to clean your keyboard. If it’s been long enough since the last cleaning, there could be enough dust in your keyboard to stop it from functioning as usual. If you are knowledgeable enough, you can clean your laptop by yourself as long as you have the right tools.
