How to Disable Fn Key on Lenovo Laptop

The Fn key on Lenovo laptops is a hardware switch that determines whether the function keys on the top row of the keyboard act as media controls or as standard F1-F12 keys. By default the media controls are activated. If you want to disable the Fn key you’ll need to access the BIOS settings.

To do this follow the following steps:

Restart your computer and press F1 or F2 to enter the BIOS setup screen.

Once you’re in the BIOS use the arrow keys to navigate to the Configuration tab.

From here find the Fn Key Behavior section and use the arrow keys to select Disable.

Save your changes and exit the BIOS.

Once you’ve disabled the Fn key in the BIOS it will stay disabled until you re-enable it or change the setting back to its default value.

However keep in mind that some Lenovo laptops use a different key to enter the BIOS such as F2 or F12. So consult your laptop’s documentation for more information. If you’re having trouble accessing the BIOS on your Lenovo laptop you may need to contact customer support for assistance.
