As title said, whenever I have the dongle plug it, when I close the lid on the laptop, it goes to sleep for a brief moment, like less than 2 seconds, than my external monitor immediately wakes up and ask for login. When I unplug the dongle, the laptop just goes to sleep and nothing wakes up.
I have tried to go in device management and unchecked the box where it allow the mouse to wake the computer but problem still persist.
Any help?
