I use softwares, that opens projects, which take some time to open, say for e.g. Unity Editor, Visual Studio etc. With the reopen windows thing, it just launches the Unity Hub, and Visual Studio Launcher. It doesn't actually open the apps to the state I was expecting, hence wasting time. I was looking for Windows like Hibernate, coz I don't need to keep it powered. Imagine, being able to resume from exact previous state, all undo history maintained, clipboard state, everything as was left previously, This is how it worked on windows.

If that's all you want, you can just put it on standard sleep. The power draw is minimal and since you have a desktop anyway, there's no battery drain concerns.

It will recover the state in a second or two this way.

Hibernate is useful if you like to keep a laptop unused for several days at a time, but in your case, it wouldn't really offer anything over regular sleep mode. The power cost savings would be a few dollars a year, at most.

Its disconnected from power during the day when I am not at home. So can't put it to sleep.
