Display gone dark
My Lenovo Z500 updated to W10 and the display is now dark and hardly readable. If you press the up/down keys for display the little control pops up on the screen - the bar moves up and down but the screen remains dark and does not vary. In device manager there are two drivers - Intel HD Graphics 4000 and Nvidia GE Force GT635M. I have removed/uninstalled both and reinstalled from downloads from the Intel and Nvidia sites direct, rebooted and nothing changed.
Any suggestions?
Thanks
Mike
