Systemctl hibernate does not resume, acting like shut-down

I grew tired of my laptop losing too much battery while in suspend and therefor wanted to setup hibernate. However, I can not get it to work. Systemctl hibernate shuts off the laptop, but it does not resume its previous state when turned on again.I use Ubuntu 22.04.4 LTS and Windows 11 in a dual boot configuration and I am trying to hibernate Ubuntu (which is the main thing I am using) on a Lenovo L13 Yoga.

I tried a lot of things I found in other posts, the last and biggest post being Ubuntu 18.04 can't resume after hibernate.

Currently I have the following configuration:

cat /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla:

[Re-enable hibernate by default in upower]Identity=unix-user:*Action=org.freedesktop.upower.hibernateResultActive=yes[Re-enable hibernate by default in logind]Identity=unix-user:*Action=org.freedesktop.login1.hibernate;org.freedesktop.login1.handle-hibernate-key;org.freedesktop.login1;org.freedesktop.login1.hibernate-multiple-sessions;org.freedesktop.login1.hibernate-ignore-inhibitResultActive=yes[Enable hibernate to be run via cron]Identity=unix-user:*Action=org.freedesktop.login1.hibernate;org.freedesktop.login1.hibernate-multiple-sessionsResultAny=yes

This is everything I can think of that might be relevant. Please ask if there is anything else I can provide.
