My up and arrow keys are not working

[Enchidio]

I was just doing some typing games when my arrow keys stopped working, specifically, my up and down arrow keys. I thought that it was because of crumbs, so I took off the key, but there was nothing visible. I tried number lock and tried to use them, to no avail. I also used the keys on the number pad when I was using number lock, and though the left and right keys (4 and 6) were working, the up and down (8 and 2) keys were not working. There is nothing physically wrong, since when I turn off number lock, 8 and 2 still work. This laptop is Windows 10, and the model is M2C92UA#ABA. Any help? Thank you in advance. I'm new to the forums so if I did anything wrong please tell me.

Greetings @Enchidio, 

Welcome to HP Forums and Thanks for the post. 

I understand that the arrow keys are working even on the Numpad, is that right?

Kudos to you for trying to troubleshoot the issue on your own.

Not to worry, I will be glad to assist you. 

Have you tried different applications to test the arrow keys?

Have you run a keyboard test on your computer?

Recommend you open device manager by doing a right-click on the Windows button.

Uninstall the keyboards listed in device manager. 

Please delete the drivers when prompted during uninstall. 

Restart your computer and check. 

If the issue persists, run a keyboard test by booting the computer system diagnostics. Click here. 

For other troubleshooting steps, please refer to this HP Article. 

Keep me posted.
