+Make sure you have SWAP > RAM
+SWAP to fstab
+find swap UUID:
+
+blkid | grep swap
+should output

+/dev/nvme0n1p1: UUID="90ee7315-b16a-4e2g-bd07-cg83703750b9" TYPE="swap" PARTUUID="abadca41-942a-6c83-88d2-db28cf41ce13"`
+copy the UUID, without the " :
+
+UUID=90ee7315-b16a-4e2g-bd07-cg83703750b9
+
+add swap to fstab
+
+sudo nano /etc/fstab
+add
+
+UUID=90ee7315-b16a-4e2g-bd07-cg83703750b9 none            swap    sw              0       0 
+
+reboot
+add swap to grub
+sudo nano /etc/default/grub
+edit GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="resume=UUID=90ee7215-c16a-4e2f-bd07-cd83703750b6" 
+
+if you DONT want kernel messages to be shown and keep the plymouth animation during boot, change to:
+
+GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=90ee7215-c16a-4e2f-bd07-cd83703750b6"
+update grub with the new settings: sudo update-grub
+
+try with
+
+sudo systemctl hibernate
+after reboot it should show all the same windows again
+
+activate automatic hibernation after delay
+To start using this function you need to create a file
+
+sudo nano /etc/systemd/sleep.conf
+add
+
+[Sleep]
+HibernateDelaySec=3600
+try
+
+sudo systemctl suspend-then-hibernate
+Should sleep for the time specified and then the screen turns on shortly and it hibernates. Try rebooting after this happened.
+
+If it works make it permanent.
+
+sudo nano /etc/systemd/logind.conf
+change
+
+#HandleSuspendKey=suspend
+#HandleLidSwitch=suspend
+to
+
+HandleSuspendKey=suspend-then-hibernate
+HandleLidSwitch=suspend-then-hibernate
+Save the file. Restart logind service by the command:
+
+systemctl restart systemd-logind.service
