I found a semi-solution, i set tlp to always using default mode = ac whenever i boot up laptop, but i think by doing so i completely made tlp useless in terms of power saving.
@Raiden0456 I don’t know if this can help but I fixed my problem today.
Seems that it is link to my hardware. It is an Asus Rog Strix G15 laptop and this bug is crossplateformed (Debian, Ubuntu, Fedora, Arch,…)
Maybe it can bring you some clue.
All the best.
