High Sierra Brightness reset to max each restart

Hi, i've installed High Sierra on my HP 250 G6 ( i5 7200 kabylake) and after a week of use, it happens that my laptop screen brightness resets to max each time I start/restart it.
It didn't do that before, so I'm wondering what is messing somewhere. I've tried reset pram by pressing F11 at clover boot, but no change. I've tried reseting nvram with terminal, but no change.
Any idea ? thanks in advance

In the end I solved this issue by re-installing High Sierra, I still don't know what was the problem but definitely not my settings in Clover or EFI partition which I kept. Maybe some nvram file stored somewhere I couldn't find, and maybe was locked or I don't know ^^

Use AptioMemoryFix-64.efi and delete all other OsxAptioFix*.efi in /EFI/Clover/drivers64UEFI/. AptioMemoryFix-64.efi may allow native NVRAM to work on platforms.
