Hello Claus Debaker,
I have seen this issue in many systems. The solution appears to be disabling Fast boot and Hybrid Sleep mode. (NOTE: I have not re-enabled one or the other to see if one solves it instead of both.)
To disable Fast Startup:
Open up Power Options in the Control Panel. In Windows 10 you can get there from right clicking on the start menu and going to Power Options Once there, on the left hand side, click "Choose what the power buttons do" Click "change settings that are currently unavailable" up at the top Down below under the "Shutdown Settings" section you will see "Fast Startup" check-boxed. Uncheck the box Click OK
To disable Hybrid Sleep:
Open up Power Options in the Control Panel. In Windows 10 you can get there from right clicking on the start menu and going to Power Options Click "change plan settings" next to your current power plan Click "change advanced power settings" Click the + sign next to "Sleep" Click the + sign next to "Allow hybrid sleep" and change setting to "off" Click OK
