Mostly curious, My motherboard crapped out and while I had it apart I did not see any micro switches or wires near the hinges.
So if the motherboard does not fix the black screen issue I was going to investigate the lid switch.
Just trying to cover all the bases.
Thanks for reply,
If you have a black screen, it might be that the backlight is not powering on. I don't know if your laptop uses a CCFL backlight or LED backlight, but if it is CCFL, it will have an inverter board. That is a common failure point. (Looking on ebay suggests it is probably LED backlit, not CCFL, so probably no inverter board.)
It is possible to replace an LED backlight in some LCD panels, but I wouldn't try. Instead you can replace the entire LCD panel for less than $100. Although there is a good chance that the motherboard will fix it.
