On one of my recently updated WIN10 v1903 laptops, I had to use the following technique to uncheck the “FAST BOOT option” recommendation in CONTROL PANEL. This 1 minute U-Tube video has step-by-step instructions. When FAST setting is enabled, the true state of machine may not be accurately captured as to whether it is coming up from a shutdown or “hibernation” modes — as the fast boot/shutdown takes some technical “short-cuts” for the extra speed in the process.  Older devices might also be more susceptible for this issue.


QUOTE:     While fast startup is a pretty harmless tool that can deliver a considerable startup speed boost, especially to PCs using hard-disk drives (HDD), some people prefer to have their PC truly shut down when they click the “Shut down” button on their PC. With fast startup enabled, choosing to shut down your PC might look like you’re completely shutting things down, but in reality, your PC is entering a mix between a shutdown and hibernation. A hibernation file is indeed used, although it is smaller than usual. Why? You’re logged off before the file is created, meaning your session is not recorded. The speed boost comes from the Windows kernel being saved on your hard drive and loaded when booting.

How to enable and disable fast startup on Windows 10

3. Type Control Panel and hit Enter on your keyboard.
4. Click Power Options.
5. Click Choose what the power buttons do.
6. Click Change settings that are currently unavailable.
7. Click Turn on fast startup (recommended) so that the checkmark disappears.
8. Click Save changes.
