Bluescreen after pluging in externel monitor

Hi there,

my UBook Pro works fine, until i plug in an external monitor via the micro hdmi to hdmi cable. After that sometimes I can work an hour or just a few minutes and then I get a blue screen with “driver power state failure”.

Sometimes the screen goes black and the system is blocked for a minute. Then the screen comes up again and after that it goes black again.

The power features are set to maximum and the intel driver & support assistent says everything is fine. And so do the windows device manager.

I’m very happy with my ubook pro, but this is anoying.
