How To Disable Or Enable Function (Fn) Keys

Every laptop keyboard has special keys that issue shortcut commands to certain functions or features. Want to put on/off your Wi-Fi?

Just press the key that has the Wi-Fi symbol on it. Want to increase or decrease your screen brightness? Look for the key that has full sun or hollow sun to do so respectfully. This makes it easier to do certain things without going through system settings.

But, most of these shortcuts are found under or on top the functions keys. Some laptops require you to press a combination of Fn + Function Key (F1, F2, etc) before it can work.

What if you want to use the function keys without pressing the Fn key? Sometimes it gets really annoying when you have to issue a command and you forget to add the Fn key. Instead, it turns off your Wi-Fi which wasn’t the plan in the first place.

Here’s how to change Fn key settings in Windows.

How To Use The Function Keys Without A Fn key

Do it Through The BIOS or UEFI Settings

You can disable or enable the Fn key through the BIOS or UEFI settings.

To enter the BIOS on Dell or Acer, restart your laptop. As soon as the logo pops up press the F2 key.

To enter BIOS on Lenovo, restart and press F1 or F2 as soon as the Lenovo logo pops ups.

To enter BIOS on ASUS, restart and press Del when the logo pops up.

Note: Some laptops require you to press F10 to enter the BIOS. Also, make sure your BIOS is the latest version if not please update it.

Now that you are in the BIOS you can now disable or enable the Fn key. To find that option look for system configuration and under it search for a function key option. Press ENTER to choose the option to disable or enable it. Not every laptop is the same. You must check under Main or Advanced to find where the function key option is located.

How To Enter BIOS Configuration

If for some reason you are not able to enter the BIOS through the steps outlined above you can do it through the UEFI Settings.

This method is for those who have the Fn lock key on their keyboard. This is the fastest way to lock or unlock your Fn key without configuring the BIOS.

Locate the Fn Lock symbol which is normally found under the ESC key. It’s not always found under the ESC key so you have to search for it if it’s not there.
