Dark Overlay at The Middle of Thinkpad Screen.
I am getting dark overlay on my Thinkpad T440s at the middle of the screen which is FHD+Touch, this dark overlay don’t always appear, sometime it appear after laptop start and disappear itself after few seconds and sometime when it appear I have to tilt the screen to make it go away sometime it appear that it hardly noticeable and sometime it dark enough to easily noticeable… If I put slight pressure at the bottom right side of the screen where dark overlay start this dark overlay go away!
my conclusion about this issue that it may be due to loose connector due to which lcd back light dim and show dark or grey overlay but problem is I don’t know how to get to that connector as I am unable to find any guide or video on internet…please help me fix this issue! Thanks
Is this a good question?
