My issue is that my Thinkpad x230t screen is somethimes just freez. More accuratly maybe will be to say as it seems like someone put a gray or sometimes black box on the screen. Sometimes you can see few lines on pixel from the screen and if i press the winkey over and over i can see something happen, and sometimes everything is just grey or black.
Basiclly i have a docking station so i can say the following:
1a) when this happens and i connect it to external monitor - everything works fine. So i guess its not the GPU.
1b) Also i guess it is not a program issue.
2) Lenovo test program doesnt detect any issue.
3)The issue seems to randomaly appear. Also the time the screen freezing is randomanly. It can be 5 sec or 5 min.
Anyone had something similar?
I thought maybe this is the cable, but than i would expect that if i move the screen i will see a response.

The cable is unlikely. I would first do a memory test. I tend to use memtest86+ but any of them would work. You have integrated graphics, so there is no separate GPU, but there are still separate connections to the LCD and external monitor. Are you always running the same software when it crashes? Can you update the graphics driver?
