Then try enabling Action Key from BIOS: http://support.hp.com/in-en/document/c02035108

Did this issue happen after upgrading to Windows 10?

You could try to factory reset using HP Recovery USB.

You can also try reseating keyboard cable if you're comfortable with to see if that is the issue.

Yes, you can ask them to check the issue considering it is not the same as it was earlier.

Mostly it is hardware issue.
