For no readily apparent reason, my shiny new SP 2017 has lost the ability to change the brightness of the screen.
Swipe from the right to the Action Centre.....brightness button doesn't change anything
Access power icon...nope
Control panel.....nope
Rummaged on line, usual suggestions, re-install the drivers for both the Surface monitor and the Intel Display driver....nope
Came across a registry tweak
Disable Intel Display Power Saving Technology on Surface Pro 4
Worked...yippee...for 2 days then back to where we were and the registry setting doesn't change anything....
Any suggestions.....?
