Hi :)
I had to replace the hard drive in a HP ENVY Ultrabook 4-1015dx, Windows 7 Home Premium X64. Did a fresh install of windows. I installed the needed drivers but now when I press FN and for example, F10, the volume does not go up as it should. I have checked for a driver but there is nothing there only for the mouse. I searched and found that it might be the HP Quick Launch Software driver, so I installed it, still doesn't work. BIOS is updated, the function is also enabled in BIOS when you press F10. It was working just fine before I had to replace the hard drive. Anyone have an idea?
