Hibernation works only when not plugged in

I'm currently dual-booting Windows and Arch Linux, and I can't get hibernation to work properly.
I have a LUKS-encrypted partition with Btrfs subvolumes on it. For the swap file, I followed this article.
When the system is not plugged in, it takes around 30 seconds to hibernate and shut down, which seems odd — when I was using GRUB instead of bootctl, it only took around 6–7 seconds.
When the laptop is plugged in, the screen goes black and the system becomes unresponsive. I have to force shutdown by holding the power button.
hardware & system info:
thinkpad t14 g1 amd, booted in uefi mode 16gb ram.

I'm currently dual-booting Windows and Arch Linux, and I can't get hibernation to work properly.

3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

When the system is not plugged in, it takes around 30 seconds to hibernate and shut down, which seems odd

Please post your complete system journal for the boot, eg.

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

for the previous ("-1") one.

Since you're using a swapfile on btrfs, make sure to have seen https://wiki.archlinux.org/title/Power_ … ile_offset (though I'd assume you got that from the btrfs article on readthedocs, too - still…)

Arch Linux
