I have a dual card laptop. When i game on Intel there is no problem. But when I game on nvidia 940mx my laptop just stops being charged and it fills screen with a random color. No sound, no ctrl alt delete react. Nothing. Just a random color and no charging. When i shutdown using power button it is starting to charge again. Also there is no charge problem when not using 940mx. I'm gaming with a monitor. Sorry for my bad English skills.
