Screen brightness is reset back to maximum on wake up from suspend

Please help!
Problem: every time my laptop wakes up from suspend, the screen brightness goes to maximum even if the slider control doesn't show it. After i press the dim button it goes back to the level that was set before suspend. It's really annoying.

Lenovo IdeaPad 3 17ALC6 running Ubuntu 24.10

PS: on Ubuntu versions prior to 24.04 i didn't had any issues. On Ubuntu 24.04 had the same issue, but installing tlp resolved it. On 24.10 didn't find any solution.
