If you’ve ever found yourself struggling with the Fn key on your Windows 10 laptop, you’re not alone. Disabling it can make your life easier, especially if you’re used to using the function keys (like F1, F2, etc.) without needing to press the Fn key. Here’s a quick guide on how to disable the Fn key on Windows 10, giving you a hassle-free experience.
How to Disable Fn Key Windows 10
The following steps will guide you through disabling the Fn key on a Windows 10 laptop. This will allow you to use the function keys (F1, F2, etc.) without having to press the Fn key.
Step 1: Access the BIOS/UEFI Settings
Restart your laptop and press the BIOS key during the boot-up process.
The specific key to access BIOS can vary based on your laptop model. It could be F2, F10, Del, or Esc. As soon as your computer starts to boot, keep an eye out for a prompt that indicates which key to press to enter BIOS.
Step 2: Navigate to the Advanced Tab
Once in BIOS, use the arrow keys to navigate to the ‘Advanced’ tab.
The BIOS interface is usually controlled via keyboard arrows. Navigate carefully to the ‘Advanced’ tab, which often houses the settings for the function keys.
Step 3: Locate Function Key Behavior
Find the option labeled ‘Function Key Behavior’ or something similar.
This setting will determine how your function keys operate. It might be listed under different terms depending on your laptop manufacturer.
Step 4: Change the Setting to ‘Function Key First’
Select the ‘Function Key First’ option and save the changes.
By setting this option to ‘Function Key First,’ the function keys will work without needing to press the Fn key. Use the instructions on the screen to save and exit BIOS.
Step 5: Restart Your Computer
Reboot your laptop to apply the changes.
Once you’ve made the changes and exited BIOS, your laptop will restart. The function keys should now work independently of the Fn key.
After completing these steps, your function keys will be active without pressing the Fn key. This can make your keyboard shortcuts and function key usage more straightforward and efficient.
