2. Press the Keyboard shortcut

Another method that you have at hand, in case you want to use the Function Keys without pressing the Fn Key, is to use the keyboard shortcut.

This is a fairly easy method to use, as you don’t have to go into the BIOS settings in order to make the change.

First, make sure you locate the Fn lock key on your keyboard, and once you find it all you need to do is simultaneously press the Fn key along with the standard F1, and F2 keys that you wish to use.

And that was all, now you can use the function keys, without pressing the Fn key. Whenever you want to switch back, you will only need to make the same steps you did previously, and that will disable the function.

3. Change UEFI settings 

  1. Click On Start Menu, and type Settings to launch Windows Settings
  2. Click on Update & Security from the list and go to Recovery on the left side
  3. Click on the Restart now button. Your laptop will now restart and it will open the UEFI settings 
  4. Click the Troubleshoot option once your Windows boots into recovery mode
  5. Under Troubleshoot choose Advanced Options
  6. Next, choose UEFI firmware Settings under Advanced Options and click on Restart.

Once you completed the above steps, you will be able to search for the function key option and make sure to disable it in the UEFI settings.

4. Use Control Panel

You will find the option to change the function keys as standard, in the Boot Camp configuration panel.

For example, if you are using Dell this option will be found in the Windows Mobility Center. Other manufacturers may have the option in the same place, so make sure to check that out.

In order to access it on Windows 10, make sure to right-click on the Start button and simply select the Mobility Center option.

It’s also possible to have this option in the keyboard setting configuration tool which can be found in the System menu or right in the Start menu.

If you are using ASUS you will see that it comes with preinstalled ASUS Keyboard Hotkeys that can be found in the Windows app.

No doubt about it can be really frustrating not being able to use the brightness or volume keys. Fortunately enough the fix for this issue is fairly simple and you can reverse the Fn functions within just a few clicks.

As you can see in the above-presented solutions, you can either make these changes from the keyboard, if you can locate the Fn key on your device.

Otherwise, you can go into the BIOS settings, and depending on which device model you are using, there are some specific steps you can make in order to make the change.
