Screen won't stop adjusting the brightness automatically

[LTSU]

So, i have this rather annoying issue on my laptop (I don't remember the exact model but it's Acer Aspire S 13). The screen is automatically changing the brightness in the stupidest way possible. When there is something bright on the screen the brighteness goes up and  when there is something dark, it dimms itself. This is super annoying because when you're watching something the screen keeps changing brightness constantly. I have turned off "Enable adaptive brightness" from power settings but it's still doing it. If anyone knows a way to fix this I'd be very grateful :).

Some laptops have a setting for this in the BIOS. Take a look in there as well.

I took a look and couldn't find anything related to this. There wasn't much more than boot settings and something related to touchpad and some s3 state lid opening resume thing . Thanks for the suggestion anyways
