Another method that you have on hand, in case you want to use the function keys without pressing the Fn key, is to use the hotkey.

This is a pretty easy method to use as you don’t need to go into BIOS setup to make the change.

First, make sure you find the Fn lock key on your keyboard and once you find it, all you need to do is press the Fn key at the same time along with the default F1, F2 key you want to use.

And that was it, now you can use the function keys without pressing the Fn key. When you want to switch back, you just need to do the same steps as before, and that will disable the feature.

3. Use the UEFI settings

You will find the option to change the serial function keys in the Boot Camp settings panel.

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

To access it in Windows 10, you need to right-click on the Start button and just select the Mobility Center option.

It is also possible to have this option in the keyboard configuration tool found in the System menu or directly in the Start menu.

If you use ASUS, you will find that it comes with pre-installed ASUS keyboard shortcuts that can be found in the Windows application.

There is no doubt that it can be very frustrating not being able to use the brightness or volume keys. Fortunately, the solution to this problem is quite simple and you can undo the Fn functions with just a few clicks.

As you can see from the solutions above, if you can find the Fn key on your device, you can make these changes from the keyboard.

Otherwise, you can access the BIOS settings and depending on the device model you are using, there are some specific steps you can take to make the change.
