Running Windows 10 - clients laptop presents a two stage semi-random flicker at low brightness levels with battery charger/external supply out.
At the lowest brightness settings the Lenovo X1 Yoga flickers between its lowest brightness setting and the next setting up - that is, it is toggling between 2 gradations of minimal brightness.
Playing with the power management settings as described in previous posts -- eg: Adaptive brightness, does nothing.
The Intel Driver is up-to-date.
I have my own X1 Carbon which is around 6 months of age that does the exact same thing - but I just either plug it in or use a brighter setting.
Question: Has anyone ever replaced any hardware (Display or mother-board) and corrected this issue?
