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.
