I don’t choose to sleep or shutdown. I want instant context saving and I will close my laptop many times a day. I expect opening it to restore me to where I was within 5 seconds with same application state and windows in the same place.

I have a MacBook which performs this flawlessly and my Linux desktop also pauses and restores flawlessly except immediately after installing new Nvidia GPU drivers.

I haven’t thought about different CPU sleep stages in approximately 9 years when I had to make my XPS M1330 handle them in the end years of its life.
