With the Function keys, you can control multiple hardware components faster and easier. Fn keys allow you to adjust screen brightness and speaker volume.
Sometimes these settings will not work. Each time you wish to modify your computer’s settings, you will need the Action Center and Settings. This guide will explain how to fix it.
1. Verify that Fn Keys do not lock
Fn keys usually stop working because someone accidentally pressed the Fn lock key. It is easy to check if the Fn Lock Key has been pressed on your Fn key.
Look for the Fn (or Flock) keys on your keyboard. Depending on which laptop you have you can press it one time or hold the key for several seconds. If that fails, press both Fn and Esc Keys simultaneously.
Next, choose one of the Function key options.
- You must ensure that your keyboard is functioning properly
If some Fn keys work, this could mean that your keyboard must be cleaned. It may be because your last cleaning didn’t take as long as you expected. If you have the skills, you can clean your laptop by yourself.
These quick fixes also work if you have a keyboard attached to your computer.
- Connect the keyboard to your computer and unplug it.
- Disconnect the battery from your Bluetooth keyboard and wait for it recharge.
- To verify that Fn keys function, connect your keyboard and computer.
