The powercfg command you ran has enabled hibernation to take place on your machine, which usually doesn't do anything but that. However, when you don't want hibernation that appears to be happening instead of sleep. I am going to try to walk you, via screen captures, where you need to look to potentially make tweaks to get the behavior you want. You should not need to disable the ability to hibernate but will want to change certain instances of hibernation back to sleep.
Step 1: Win10 System -> Power & Sleep Settings
Click the noted link above and this will take you to
Step 2: The good, old-fashioned Control Panel Power Options Dialog:
Step 3: Check your Power Plan settings with regard to sleep:
You won't likely find anything amiss there. Choose, of course, the link next to whatever power plan is active on your machine.
Step 4: Power button settings
When you come in to this dialog, it is most likely that the options at the bottom will be stippled out and inaccessible. You must click the link noted to make them "go live" and become accessible. If you're interested in faster boot times, and Fast Boot is not enabled, you may wish to enable it to give it a try. You can also choose the options that will pop up when you hit the Start Button and choose the Power Menu here. I am guessing that you're accustomed to pressing the power button quickly to induce a forced sleep, and that this option will have been changed in this dialog such that a hibernation is being triggered instead. If that's the case, use the dropdown lists to change hibernate back to sleep.
I always use the Start Button->Power menu to choose what I actually want to do because it guarantees that I'm going to get the action I want.

In a modern society where everyone thinks their opinion deserves to be heard nothing annoys me more than individuals who mistake their personal preferences for fact.
