Function keys (F1–F12) on a keyboard provide quick access to various system functions such as adjusting volume, controlling brightness, opening help menus, refreshing pages, and performing shortcuts in different applications. On many laptops, these keys also control hardware features like Wi-Fi, screen brightness, and media playback.
However, users sometimes encounter issues where the function keys stop responding or perform incorrect actions in Windows 11. This problem may occur due to disabled function key settings, keyboard driver issues, BIOS configuration, or conflicts with manufacturer keyboard utilities.
If the function keys are not working in Windows 11, follow the troubleshooting steps below.
How to Fix Function Keys Not Working in Windows 11
Work through the following solutions in order. After completing each step, test your function keys again.
1. Check the Fn Lock Key
Many keyboards include an Fn Lock feature that changes how function keys behave.
- Look for a key labeled Fn Lock or an Fn + Esc shortcut.
- Press Fn + Esc to toggle the function lock.
- Try using the function keys again.
If the Fn Lock is enabled, the keys may only trigger special actions instead of standard F1–F12 functions.
2. Restart Your PC
Temporary system glitches can affect keyboard functionality.
- Close all open applications.
- Press Windows + X.
- Select Shut down or sign out > Restart.
- After restarting, test the function keys again.
Restarting refreshes input devices and system processes.
3. Check Keyboard Settings in BIOS/UEFI
Some laptops allow you to configure function keys in BIOS.
- Restart your computer.
- Enter BIOS/UEFI settings (usually by pressing F2, Del, or Esc during startup).
- Look for settings such as:
- Function Key Behavior
- Action Keys Mode
- Set the option according to your preference.
- Save changes and exit BIOS.
This ensures the correct function key behavior.
4. Run the Keyboard Troubleshooter
Windows includes a built-in keyboard diagnostic tool.
- Press Windows + I to open Settings.
- Go to System > Troubleshoot.
- Click Other troubleshooters.
- Locate Keyboard.
- Click Run and follow the instructions.
The troubleshooter may detect and fix keyboard-related issues.
5. Update Keyboard Drivers
Outdated or corrupted drivers can cause function key problems.
- Press Windows + X.
- Select Device Manager.
- Expand Keyboards.
- Right-click your keyboard device.
- Select Update driver.
- Choose Search automatically for drivers.
- Restart your PC after updating.
Driver updates often resolve compatibility issues.
6. Reinstall the Keyboard Driver
If updating the driver does not help, reinstall it.
- Open Device Manager.
- Expand Keyboards.
- Right-click your keyboard device.
- Select Uninstall device.
- Restart your PC.
Windows will automatically reinstall the keyboard driver.
7. Check Keyboard Manufacturer Software
Some laptops require special keyboard utilities.
Examples include:
- Lenovo Hotkeys Features Integration
- HP Hotkey Support
- Dell QuickSet or Dell Keyboard Manager
- ASUS ATK Package
Install or update the appropriate utility from your laptop manufacturer’s website.
8. Disable Filter Keys
Filter Keys can sometimes interfere with keyboard input.
- Press Windows + I.
- Go to Accessibility > Keyboard.
- Locate Filter Keys.
- Ensure the feature is turned Off.
After disabling Filter Keys, test the function keys again.
9. Install Windows Updates
Outdated Windows builds may cause keyboard compatibility issues.
- Press Windows + I.
- Go to Windows Update.
- Click Check for updates.
- Install available updates.
- Restart your PC.
Updates often include fixes for hardware and driver issues.
Conclusion
If function keys are not working in Windows 11, the issue is usually caused by Fn Lock settings, BIOS configuration, outdated drivers, or missing keyboard utilities. In most cases, toggling Fn Lock or updating keyboard drivers resolves the problem quickly.
By following the troubleshooting steps above, you should be able to restore the functionality of your function keys and use them normally for system shortcuts and application commands in Windows 11. If the problem persists, checking BIOS settings or installing manufacturer keyboard drivers may help resolve the issue.
