I bought an HP Envy 17 laptop about a year and half ago. The laptop has a physical digital volume dial with a beats button in the middle:
It changes volume by turning the dial and opens the beats control panel when pressing the button in the middle.
When I first got the laptop, I purposefully disabled the button because I didn't like the graphic it put on the screen every time I changed the volume:
Now, I'm trying to re-enable it but I can't remember how I disabled it. Any suggestions?
