XPS17 L702X Windows10 update screen brightness no longer adjustable

I updated windows 7 to 10 on this laptop.

It works fine, except that the brightness of the screen can not be adjusted anymore. Dell is not supporting this product for Windows 10, which I think is odd, since it is only 4 yrs old and a high end model.

Is there a solution or work around? Downgrading to windows 7 again is not really an option.

Any help appreciated.

It is possible the screen brightness is controlled via a driver windows 10 does not cover, as such it would be up to Dell to provide the driver (which they won't since its not supported).  Have you tried adjusting the brightness in the control panels?  I would look under displays in the old style control panel and see if there is a way to adjust it there, or you can right click on the desktop and hit properties and see if its there.  It sounds like windows 10 doesn't know the panel is adjustable hence the driver issue 😞
