Zbook 17 g3 M4000m brightness controll not working

Microsoft Windows 10 (64-bit)

Hi all,

When I enable Nvidia M4000m on my Zbook 17 G3 (1ZX83US#ABA), I cannot regulate brightness.

I would tolerate it if the brightness was locked on max, but it is just the opposite. The brightness is low cannot be regulated.

Regulating slider icon appears on the screen when Fn+F5/F6 is pressed, and the slider moves but nothing changes.

I have found the similar question on the forum but there are so many suggestions, and I am not prepared to try them all.


Is this a known problem with a single (and simple) solution or I will have to keep on using built in Intel graphics.
