I have a problem with my HP 350 G1 Notebook. Sometimes it happens that suddenly the right bottom corner of the screen gets slightly darker than the rest of the screen (please see attachment). Once I move the notebook a bit or close and open the screen again it usually works again.
So far I have no idea what the source of this issue might be. I've heart of many people having backlight problems, but as far as I understand this would lead to a completely dark screen.
The problem does not occur with an external monitor, so it is pretty sure that it is not a problem of the GPU.
Does anyone of you have an idea what the problem is and how to fix it? There is no more warranty on the device and I'd like to do the repair by myself.
