Difficulty setting up hibernation - shuts down instead

Hi, I’ve tried to implement hibernation on my laptop 13 ai300 that is running fedora 43. I did it by running the commands provided at Fedora 43 Hibernation Setup · GitHub and seems to have no trouble doing so but if now try hibernation the computer just shuts down instead. I’m wondering if anyone can help me work out what has gone wrong or if this is just too hard to do let me know if I need to undo anything that I’ve done to my system.

As said, I thought I followed the whole process without issues. I did turn off secure boot at the start.

If I now run swapon --show I get:

NAME TYPE SIZE USED PRIO
/dev/zram0 partition 8G 1G 100
/var/swap/swapfile file 15G 0B -1

which I understand as showing that I did create the swap partition but that it is not being used because it is a lower priority than the dynamic swap. I haven’t got much further!
