Screen button problem on new GeminiBook 2K


I received a brand new Gemini Book 14" 2k laptop and screen buttons dont work to adjust screen luminosity, same thing if i try to adjust with windows directly.
I can’t use it at night or low ambiant light (really too bright for eyes) and battery is draining quickly because of that. Only 3h with full battery…
Any solution ? i can’t stay like this for a brand new laptop !!
