I have a thinkpd yoga s1 first gen that had almost all known problems to this type of notebook( power sleep problem, ghosting ect.)
The new one is that after installing a windows 10 update the system rebooted and then the screen stopped working at all.
I connected the notebook with hdmi to my external lcd and the system booted correctly and everything looked fine.
Strange thing is tha digitizer is working also touch is working but screen shows nothing.
I replaced the screen including digitizer but unfortunately it is the same situation.
I know that this may be a hardware issue but if someone has had the same situation i would apreciate some hint.
