You can control multiple hardware features faster and more easily with the Function keys. You can adjust the screen brightness and control the speaker volume using the Fn keys.
Sometimes, however, these settings stop working. You will need to open the Action Center and Settings each time you want to change your computer’s settings. This guide will show you how to fix this problem.
1. Verify that Fn Keys are not locked
The Fn keys stop working most of the time because someone accidentally presses the Fn Lock key. It’s easy for you to see if your Fn keys have been locked by the Fn Lock key.
Look for the Fn or Flock keys on your keyboard. Depending on the laptop you have, you can press one time or hold it for several seconds. If that doesn’t work, press both the Fn and Esc Keys simultaneously.
Next, use one of the Function keys.
2. Make sure your keyboard is working properly
It could be an indication that your keyboard needs to be cleaned if certain Fn keys still work. If your last cleaning was not long enough, it could be that there is enough dust on your keyboard to prevent it from working as it should. You can clean your laptop yourself if you’re competent enough.
These quick fixes are also available if you have a keyboard connected to your computer.
- Reconnect the keyboard and disconnect it.
- To use a Bluetooth keyboard, disconnect the battery and wait for it to recharge.
- Connect your keyboard and computer to verify that the Fn keys work.
3. Run the Hardware and Devices Troubleshooter
You could access the Hardware and Device troubleshooter through the Control Panel on older Windows versions. To access the Hardware and Device troubleshooter, you will need to use a command-line. Here’s how to do it:
- Search for the Command prompt in the Startmenu Search Bar and choose the Best Match.
- Type msdt.exe -id DeviceDiagnostic.
- Enter by pressing
This will open the Hardware and Devices troubleshooter. To begin the troubleshooting process, click Next
4. Run the Keyboard Troubleshooter
The Hardware and Devices troubleshooter didn’t solve your problem and fix the Fn keys, but there is another Windows tool that you can use. You can now access it via Settings.
- Open Settings and head to Updates & Security.
- Select Troubleshoot from the left pane.
- Click Other troubleshooting.
- Fix other problems. Click Keyboard > Run troubleshooter.
5. Turn Off Filter Keys
Filter Keys is a Windows feature that prevents repeated keystrokes. It might be beneficial to disable it, though, in order to improve the Fn keys functionality.
- Open Control Panel.
- Go to View and choose Large Icons or Small Icons.
- Click Access Center.
- Select To make it easier to use from the Explore All Settings menu.
- Go to the Make typing easier and de-check the Uncheck Filter Keys.
- To save your changes, click Apply > OK
6. Updating your Keyboard Drivers
It is possible that the Fn keys stop working due to a corrupted, outdated or damaged driver. The problem can be fixed by updating the keyboard driver.
These steps will allow you to update your keyboard driver using Device Manager.
- Right-click start and select device manager.
- Add Keyboard to your wish list.
- Right-click on the driver and choose the Update driver.
- Select the Search automatically to find drivers, and then click Start.
Download the keyboard driver from the manufacturer’s website. Make sure that you have the correct driver for your Windows version. It will cause you more problems.
