It can be frustrating if FN (function) key doesn't work correctly. Many Dell laptop users have reported FN key not working issue after upgrading to Windows 10. If you're experiencing the same issue, don't panic. Follow the steps of the methods in this post, then the problem should resolve.

Try all methods one by one starting from Method 1. If that method doesn't work, try the next method.

Method 1: Press Fn + Esc on your keyboard

This method is very simple. Just press Fn + Esc on your keyboard. It has worked for some Dell laptop users. Why not have a try?

Method 2: Update Related Drivers

The problem is not just caused by keyboard drivers. It could be due to other driver issues like chipset driver issues and display driver issues. If Method 1 doesn't resolve the problem, try to update the drivers. Go to Dell's website to check for the latest drivers of your laptop.

If you don't have the time, patience or computer skills to update the drivers manually, you can do it automatically withDriver Easy.

1) Download and install Driver Easy.

2) Run Driver Easy and click Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to one driver to automatically download and install the correct version of this driver (you can do this with the FREE version). Or click Update Allto automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you'll be prompted to upgrade when you click Update All).
