@kaia Such a fun curiosity. We have now some sort of system hibernation but without saving any data and storing data in the memory, instead of real system shutdown. By the software is a like. Shutting down win95 is totally different from shutting down winXP. I mean internally, by looking what the OS does from the moment of pressing the power button. For modern mobile phones is a same story. They are many such curiosities in the IT world 😉 For example battery level state display.
