Is it greyed out or are you able to select it? It automatically dims or brightens the screen depending on light levels in the room, which is obvious by its name. I usually turn it off on my own laptop as I do not like the brightness being variable, but some people like it.

Yes I see but are you able to switch it to enabled or is it "greyed out" (not able to be activated)? 

HP Recommended

Then it is working. Try using it in a low light and then a higher light and see if the screen brightness automatically adjusts.
