Question: Power Management Confusion - autopoweroff vs standby vs hibernatemode
Good evening everyone,
Acording to manual autopoweroff sets whether to go into low-power sleep or standby mode. But what's the difference?
Can someone explain difference between low-power sleep and standby mode please?
My iMac have set by default both standby 1 and autopoweroff 1 with standbydealy 10800 and autopoweroffdelay 28800. I'd like to know which state exactly applies when and which of them actually takes priority?
How does hibernatemode go with all that above together???
I was thinking when my iMac (probably like other desktops) have hibernatemode set to 0 it should fall just into the plain sleep where no memory supposed to be written to disk. But what surprise, if I check timestamp of my /var/vm/sleepimage file it's pretty current with file size over 2 GB.
The point is, I don't wanna bother SSD portion of my Fusion Drive with recurrent sleepimage file writing and I don't mind keep my memory powered all the time during simple plain sleep, but how can I configure this with 'pmset' properly?
Thank you guys for explanation and maybe advice, have good night, bye.
