No option to "hybrid sleep" on reaching critical battery level

I wish to put the computer to hybrid sleep automatically when it reaches critical battery level. I do not find such an option.

Here’s where I checked:

System Settings > Power Management > Advanced Power Settings > Battery Levels > At critical level:

Only the following options are available:

  • Do nothing
  • Sleep
  • Hibernate
  • Shutdown

hybrid sleep is a variation where the system is put to sleep then after a period it is hibernated.

On critical level you don’t want to hybrid - you want to hibernate or shutdown.

And it requires swapspace the size of your system RAM + GPU RAM if applicable.

Apparently not. Quoting from ArchWiki:

[Hybrid suspend] saves the machine’s state into swap space, but does not power off the machine. Instead, it invokes usual suspend to RAM. Therefore, if the battery is not depleted, the system can resume from RAM.

Well if the option to sleep is available on critical level, then I don’t see why the option to hybrid sleep shouldn’t.

Sure, and I must have it because I do have the option to hybrid sleep or to hibernate under the usual power settings. In the critical level setting though, hybrid sleep alone is missing, and that’s my concern.

Choice of words - then end result the same - fast resume if not hibernated.

One can ponder over many things and wonder why it is not done the way one expect.

In the endless possibilites in system components and system configuration yours may be the one which may not have the exact specification to make it possible - who know?

I know the perfect power save option is summarized in these two words entered in a terminal

systemctl poweroff

Sure, that is a possibility, and of course — like some Linux enthusiasts — I’m just curious what that component/spec might be. Hence the post.

But then, when you’d said,

On critical level you don’t want to hybrid - you want to hibernate or shutdown.

to me it sounded like you went too far in assuming what a user would want. A user can certainly want to hybrid sleep on critical battery level. :smiley:

Now I get it. When you’d said,

hybrid sleep is a variation where the system is put to sleep then after a period it is hibernated.

I assumed that you meant “it is hibernated automatically.” My bad.
