Secure boot currently results in the Linux kernel disabling hibernation for security reasons IIRC.

That is true, I had (perhaps incorrectly) assumed the previous commenter was talking about it affecting power consumption in “normal” suspend rather than hibernate. (I actually can’t use hibernate anyway because I use ZFS, but that’s a different story.)
Do you have a link to further elaboration and testing on this? Seems strange, and searching the forums is a bit difficult since the two terms get mentioned together a lot.
