How to Disable Fn Key Windows 11: A Step-by-Step Guide

Disabling the FN key in Windows 11 can be done in a few simple steps within your computer’s BIOS or UEFI settings. This function key, often found on laptop keyboards, can sometimes be a nuisance, especially if you frequently use the function keys for other shortcuts. By following this guide, you’ll be able to toggle the FN key behavior and customize your keyboard to suit your needs.

Step by Step Tutorial to Disable FN Key Windows 11

Before we dive into the steps, it’s important to note that disabling the FN key will allow you to use the function keys (F1-F12) directly without having to press the FN key simultaneously. This can be particularly useful for gamers or anyone who uses keyboard shortcuts regularly.

Step 1: Restart your computer and enter the BIOS/UEFI settings

To access the BIOS or UEFI settings, you’ll need to restart your computer and press a specific key during the boot-up process. This key is often displayed on the screen during the startup and is commonly the Delete, F2, F10, or Esc key.

Once you’re in the BIOS/UEFI settings, you’ll be greeted by a menu where you can adjust various system settings. The BIOS/UEFI interface can vary depending on your computer’s manufacturer, so the actual steps may differ slightly.

Step 2: Navigate to the Keyboard settings

Within the BIOS/UEFI menu, look for a section related to the keyboard or system configuration. This is where you’ll typically find the option to disable the FN key.

Some systems may label this setting as "Action Key Mode," "Hotkey Mode," or something similar. You may need to use the arrow keys to navigate through the menus.

Step 3: Disable the FN key or change the function key behavior

Once you’ve located the relevant setting, you can change the behavior of the FN key. This might involve disabling it entirely or toggling a setting that changes the default function key behavior (e.g., F1-F12 keys working without needing to press the FN key).

Make sure to read the on-screen instructions carefully, as changing BIOS/UEFI settings can affect your system’s functionality. Only make changes that you fully understand.

Step 4: Save your changes and exit the BIOS/UEFI

After adjusting the FN key settings, you’ll need to save your changes. This is usually done by pressing the F10 key or navigating to the "Save and Exit" option.

Confirm any prompts to save your changes, and then your computer will reboot with the new FN key behavior in effect.

After completing these steps, your FN key will be disabled, and you’ll be able to use the function keys directly. This can streamline your workflow and make it easier to use shortcuts that rely on the F1-F12 keys.

Tips for Disabling FN Key Windows 11

  • Before making any changes, ensure you understand what each BIOS/UEFI setting does to avoid any unwanted system behavior.
  • If you’re unsure about entering the BIOS/UEFI settings, consult your computer’s manual or the manufacturer’s website for guidance.
  • Keep in mind that the exact steps to disable the FN key may vary depending on your computer’s make and model.
  • If you’re unable to find the setting to disable the FN key, consider updating your BIOS/UEFI to the latest version, as newer firmware might have this option.
  • Remember that disabling the FN key might change how other keys on your keyboard function, such as volume or brightness controls, so be prepared to adapt to these changes.
