FOUND THE PROBLEM:
edit the registry Key hkey_local_machine\software\Microsoft\Windows NT\CurrentVersion\WinLogon and modify PowerdownAfterShutdown and change it to 1
Source: Windows 10 wakes randomly from hibernate - Microsoft Community
Summary: this setting prevents the computer from fully powering down upon "hibernation" if it's set to 0.
Response: Who knew there would be any question? But apparently it's one more straw in the nest. If it doesn't work - I'll be back. Upvote please.
My Original post (background facts and personal peeves and observations):
Also have situation - with no teamviewer. The O.S. settings are being ignored, and no WAKE shows up in powercfg -lastwake. At first I thought that there was some intent to wake it - we all did. That is not true - it is just failing to power down. Note that this error is a prime security issue. And, it is standard operating procedure for Microsoft with its impossibly arbitrary levels of complexity, to create the situation incidentally (not accidentally.) They weren't happy with just being impossibly stupid since the browser wars - they had to double down again and again. Someone needs to go in that place and seriously reformat their drive.
