If your laptop is using a recent AMD Ryzen based SoC:

ACPI C4 power state (for powering down more of the SoC during S0ix suspend) is not supported on Linux yet, for recent (last couple years) AMD processors.

Patches submitted for 6.18 were described as "laying the foundation for AMD C4 support". So, maybe won't be fully supported until 6.19 or even later; Sorry, I haven't followed up to see what has actually landed.

I have one of the older ones. I think there's a way to set up "real" hibernation on Linux but it seems like a pain in the ass
