I recently bought an HP Omen 17 and the F1 through F12 keys don't do their proper functions such as the F5 refresh unless I push the FN key. Instead, they do things like lowering the brightness, changing the volume, skipping to the next track etc. by default. I want to switch it around so when I hit the F1 through F12 keys they do their proper functions and when I hit the FN key, they do the functions illustrated on the key. How can I do this?
