Yeah I’m using this program for screen filter https://www.nelsonpires.com/software/dimmer
I don’t think there is a solution, they change the version of the computer without notice, for example new version also has better backlight and delete key in top right instead of a blank key. With my old Chuwi Lapbook 14.1 I could get 9 hours of use with screen at 0%, so it’s a shame the BMAX doesn’t allow it any more.
