Fixes for Fn key not working in Windows

Fix 1: Update your keyboard driver

This problem may occur if you are using the wrong keyboard driver or it’s out of date. So you should update your keyboard driver to see if it fixes your problem. If you don’t have the time, patience or skills to update the driver manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing. Driver Easy handles it all.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 steps (and you get full support and a 30-day money back guarantee):

1) Download and install Driver Easy.

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

3) Click Update All to automatically download and install the correct version of ALL the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

You can also click Update to do it for free if you like, but it’s partly manual.

4) Restart your computer for the changes to take effect.

5) Check to see if the Fn key work properly. If yes, then great! If it’s still not typing, please try Fix 2, below.


Fix 2: Uninstall your Synaptics driver

It’s also possible that your current Synaptics driver is in conflict with Windows 10 and triggers the Fn key not working issue. We can try uninstalling the driver and see if it fixes the problem.

Here’s how:

  1. On your keyboard, press the Windows logo key 
     
    and R at the same time, then type devmgmt.msc into the box and press Enter.

  2. Double-click on Mice and other pointing devices > your Synaptics device.

  3. Click Yes to confirm the uninstall.
  4. Restart your computer and check if the Fn keys work fine this time. If the problem persists, don’t worry. There’s one more fix to try.

Fix 3: Run Hardware and Device Troubleshooter

If the fixes didn’t solve the situation, then you can run Hardware and Device Troubleshooter, a helpful built-in Windows tool and see if it can fix the Fn key not working problem.

To do so:

  1. On your keyboard, press the Windows logo key and type troubleshoot, then click Troubleshoot.

  2. Locate and click on Hardware and Devices and click Run the troubleshooter.

  3. Click Next and follow the on-screen instructions to fix the issues it detects.
  4. Restart your computer and test the Fn key on your computer to see if they’re working properly.
