Shutdown Power State Chaotic

I have erratic behavior with power/sleep states.

In fact, the main problem is that, after shutdown, the system is unable to cut power to the laptop.

On other occasions, a RESTART leads to a POWER OFF.
On some more rare occasions, a RESTART leads to a POWER OFF, followed by a POWER ON.

This renders the sleep function unusable, and mostly having to resort to leaving the machine ON vs OFF.

If I was sure that the system shuts down completely before POWER OFF issue, I wouldn’t mind that much, but I am not sure what happens at that late stage.
