I replaced my screen on my L440, because it would not show any sign of being alive anymore (external monitor workds fine). I used this "opportunity" to upgrade it to full hd, also replaced the connecting cable.
Nonetheless, my screen is still always dark - in Windows, as also for the bios or post screen (external works fine here).
Depending in which panel I install, the old low res or ne full hd, the resolution on the external monitor responses to that (clone mode).
Thus I assume, the both cabels are fine, both panel are fine, the system recognizes them. But why is it still blank.
Also tried to trigger closing the lid with a magnet (next to the webcam), only shutsdown then.
