PC sleep modes are a mystery to me. I don't play with this stuff because I don't understand it. But I have a few itches I want to scratch: - my MacBook Air's battery charges lasts a lot longer sleeping when running MacOS than when running Fedora Asahi. - tablets with only "Modern Standby" capability didn't sleep well under Linux (haven't tried in a few years) This documentation might help. I haven't done the experiments. <https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate> Arch Linux documentation is often very useful.
