so i bought this bmax y11 from banggood last week and for nearly a week i have tried everything to get the brightness settings to work drivers all bios settings even tried Linux.
Nothing will budge the laptops from 100% screen brightness tried every windows and registry setting so battery dies in 1.5hrs max. this is obviously a bios issue with this junk or faulty system board but bmax do not supply bios updates so this is for the dustbin.
