So my machine is having an issue with an external monitor. If I hook the machine up to the monitor, and close the laptop lid. When I wake up the laptop, whether it be at that moment, or hours later after it has slept from using it, the LCD on the laptop goes on, and stays on. There is no picture on the laptop, and the external works as it should. Does your laptop do this? The internal LCD should not be going on from a sleep resume in clam mode.
