Black Screen on laptop / Connection with monitor stops
Hello,
I have a Lenovo Z710 laptop. It has keyboard like THIS. On F9 key it you can turn on/off laptop screen. Do you know what Im talking about? Remember this for later. Also, I always use external 24" Dell monitor, 99% of time.
I have the following problem. Every day, once or twice, out of nowhere my laptop screen goes black and my external monitor gets disconnected. I dont know the exact reason, but I think the issue might be with nVidia graphic card. I have 2 GPUs, as you can see in my specs info.
But Im not sure. Every time I run a game with nVidia (Modern Combat 5), in just a matter of minutes, the game crashes. So that's why I always use integrated intel graphics. But the issues still happens. That's why Im not sure that nvidia card is the problem.
Now that I described my problem to you, I would appreciate if someone can tell howcould I diagnose the problem??
Regards
