PC reboots after hibernation

KKRohr 26 Reputation points


I have 2 new PCs, one "Mini-PC" Mele Quieter 3C and a "Normal" PC with an AMD Ryzen CPU. On both PCs there is a clean install of Windows 10 and no special additional hardware inside or connected to the PC.

I send both PCs to hibernation as I use them as a mediacenter. I switch of the power afterwards. Now when switching them on, in 7 out of 10 cases the screen stays black for a while and the PC does a full reboot and will not come back to the last session. In 3 out of 10 cases the PC will wake up normally from hibernation. When the computer will do a full reboot there is a message in the event manager like "The system has rebooted without cleanly shutting down first". On my office computer I am using hibernation since 15+ years and never had this kind of problems.

What could cause this problem on 2 new computers?

Thank you for any help.

    There are many reasons why the computer cannot wake up after sleeping. Here are some potential solutions that might help:

    Reset Power Settings to Default: Open Command Prompt (type CMD in the search box and click on it). Type powercfg –restoredefaultschemes and press Enter.

    Disable Fast Startup: Go to Power Options > Choose what the power button does > Change settings that are currently unavailable > Uncheck ‘Turn on fast startup (recommended)’ > Click Save changes.

    Update Intel Management Engine Interface: Go to Device Manager > System Devices > Right-click on Intel ® Management Engine Interface > Choose Properties > Power Management tab > Uncheck ‘Allow the computer to turn off this device to save power’ > Click OK, close Device Manager, restart your computer.

    Check Task Scheduler Settings: Type Task in Windows Start Search box > Click Task Scheduler > Navigate to Task Scheduler Library > Microsoft > Windows > UpdateOrchestrator > Double click on Reboot > Go to Conditions tab > Uncheck ‘Wake the computer to run this task’ option > Click OK.

    Run the Power Troubleshooter: Open Settings > Update & Security > Troubleshoot > Additional troubleshooters > Under the “Troubleshoot” section, select the Power option > Click the “Run the troubleshooter” button > Continue with the on-screen directions.
