Screen randomly dims and brightens on thinkpad s230u

kernel: linux
screen driver: intel-backlight
inxi log: - inxi log from s230u

the brightness on my laptop seems to random dim or brighten, with dimming happening in stages until it completely disables the back light, which makes it a pain to use the laptop with this happening within a few minutes of starting the session. i have disabled all setting in the power settings but that seems to not have done everything. i had also tried removing the keybindings for the brightness keys but that also seems to have done nothing. this problem persists even when plugged into the wall.
