I have a surface pro 6, and for months I was looking for a solution to why it was constantly waking up immediately after going into sleep mode. I'd have to press the power button a second time as it was waking up just for it to stay asleep. After getting fed up I started exiting apps that were running from my system tray and found after testing 1-by-1 that unloading multiplicity seems to stop the behavior. Digging a little deeper I found that it only seems to happen when it is set as a primary computer rather than a secondary. If it helps at all I know the event viewer says the cause of it exiting standby is from "Input Keyboard". I also wasn't sure if this was the right place to post this bug but please let me know. I figure I can work around it because I'm not constantly using the program, but it would be nice if the behavior could be fixed.
