Suspend != boot

Even in 2010 or earlier waking a pc from suspend would have only taken 2-3 seconds because the whole system state is in RAM not on disk.

Looking forward to seeing if it persists with Linux

I have never had what you described happen in my past 15 years of using linux, i hope you find your way around things, linux is dope once you get used to it.

My PC goes down from 70W idle to 2W when suspended. I also have a master slave power strip, that turns of all my peripherals (speakers, lights, audio interface, etc) when the PC drops below 10W so that saves some extra energy.

It has never occured to me my whole life to not suspend or shut down computers overnight. It wakes up in like 2 seconds why wouldnt you, even if it used only an extra 1W
