Windows 10: Any Windows initiated shutdown/restart results in failure to POST

I'm don't organize my thoughts well, so please bear with me.

Issue began, I THINK, with a Windows update a few months ago.

Any Windows initiated shutdown/restart results in failure to post with the exception of the shutdown option in the start menu. Restart results in failure to post. Shutdown from CMD prompt results in failure to post. Fast startup is deselected in power options. Keyboard backlight, fans, and other laptop LEDs turn on, but I get no display, no splash screen. If I hold the power button to shut off at that point, it will boot normally. If I hold the power button to shut down from within Windows, it'll boot normally. As said, if I select shutdown in the start menu, it'll shut down and boot normally (I'm wondering if fast startup is truly turned off for this reason, even though the option is off - maybe the shutdown isn't giving me a true shutdown).

I ignored the problem for a couple months, but did a fresh Windows install last night and the issue persists. I don't know for sure that it's not a hardware problem, but it only has a problem on a windows initiated shutdown, so I'm not convinced its not Windows. Laptop is still under warranty so it won't be a problem to send it in other than losing my machine for 6-8 weeks for repair. I'd like to rule out software before I go that route.

Any help would be sincerely appreciated

Windows 10 Restart and Shutdown failure

Thank you. I have, in fact, done one of the things you suggested after I posted the issue. I discovered a couple of new Windows 10 updates that had not downloaded and then I installed them. My problem seems to have gone away! I had traced my failure to
the date of the last Windows 10 update and was preparing to remove that update. But the newest update for x64 machines seems to solve the problem. I haven't thoroughly tested it yet, but I have done a couple of successful Shutdowns and Restarts without the
failures I've had for a week. Thanks again.

Me again. After further testing, I still have the same problems with Restart and Shutdown/restart. I'm back to using Sleep all the time and having to sometimes cold-boot 2-3 times in a row to get WINDOWS 10 to start correctly. Have done a total system Reset
already and re-installed Windows 10 and installed all the updates. Looks like I'm just screwed.

This OldTimer also seems to be screwed. I'm experiencing the same problem for several months now. At least I'm not alone in the boat.
