My laptop (HP ENVY) isn't actually changing its brightness when I switch brightness.

[Windows Central Question]

Basically the title says it all, my computer is stuck on max brightness so the battery is suffering and using my laptop at night is now a pain. I already updated the display adapter and the option to change the brightness in my display settings is there but moving around the slider doesn't actually do anything.

did this always happen or has it started recently? Any changes that happened around the time this issue popped up? Like dropping the laptop or doing an upgrade or something?

The only major download that had happened was when I (accidentally) upgraded to windows 10, otherwise no major downloads of any sort or damages to my laptop.
