Yes, I and re-booted again, and still doesn't work.
I also did a Windows update, rebooted, and doesn't work.
The Power Option Hibernate takes about a minute to wake up, so don't like that.
I tried all these options and more, and gave up.
But... per chance, I was trying to fix an unrelated battery problem, and it was suggested I disable blue-tooth.
I tried it, and both the ScreenSaver and Screen part of Power Options both work fine now.
