    Hi rcten.

    Just to ensure your computer is not actually in hibernation and is failing to awake from it, would you mind trying to disable hibernation and see if that corrects the situation.

    Command prompt(admin) enter the folllowing

    powercfg -h off

    Shutting off hibernation also disables Windows Fast Startup but this is just a test. To turn hibernation on, same command but change off to on

    the command

    powercfg /devicequery wake_armed

    will list all devices that system thinks can wake it.

    Another item you may wish to try is to reset your power plan back to defaults. Then restart computer and customize back to your preferences.
