I apologize for the delayed response.
The FN + ESC feature also requires the latest version of HP Support Assistant.
The best recommendation I have for Beats, is to reinstall Windows from the HP Recovery Manager and set everything back to factory conditions. Reinstalling from the Recovery Manager will correct any software/registry glitches or issues. You'll want to back up all of your personal files (documents, pictures or any other file you want to keep), before performing a Recovery.
Let me know the results when you get a chance :)
