i have xps 15z device and i got some problems with it
when i install win 8.1 and try to install the video driver intel hd 300 a message that i dont got the minimum requierment appears
and after i restart my lap i find the driver installed but when i plugged out the charger and work with batteries the screen flash and turned to black and white and back to normal and so on
so i dont know if the problem is from my graphic card or the driver or win 8.1 pro incompatibility
can u tell me what should i do please
