I've been having the same problem for years. Windows 10. I don't have "Change Settings that are currently unavailable", nor do I have Hybrid Sleep.
Got the same problem since last update.... Power button, keyboard nothing gets my laptop out of sleep. Also the solution is not given in my system
For Windows 10
You will need to go through the Control Panel. Then navigate to: Power Options --> Change when computer sleeps --> Change advanced power settings
This pops up a smaller window. You can change your power setting here (I keep mine on high performance), and in the menu tree below that, you'll see Sleep. Open that to find Allow Hibernate Sleep. Note that there is a setting for both battery and plugged in, and you will need to turn these on for each power mode (High Performance, Balanced, and Battery Saver) you use.
