Sometimes I am unable to abdjust the brightness of the screen.

 

The onscreen brightness level indicates the brightness level is changing but the actual screen brightness remains the same.

Auto brightness is off, of course.

 

It fixes, sometimes, by restarting, but often fails.

 

Any suggestions?

    Yes, tried all different options, thanks.

     

    I ended-up checking if there are any driver updates and saw there is one for the VGA Driver. Since then the problem has not re-ocurred but I'll wait a while before I confirm the problem is solved.

    Have you gone to Control Panel>Power Options and adjusted the slider at the bottom ? It is different when on power and when on battery.

    My switch 10 has the same problem. It only happens at times after docking or undocking. Never happens while using as tablet

    It seems the driver update worked, no problems since.
