Hibernate is working fine.
Sadly tough, when hibernating, my PC directly restarts.
This is my CPU: 11th Gen Intel i7-1165G7 (8) @ 4.700GHz and GPU: Intel TigerLake-LP GT2 [Iris Xe Graphics].
As it is written here
hibernate writes the contents of the ram to disk and reaches a zero battery consumption state. In my case led on Power button is OFF.
I could be wrong.
I made a swap partition same size as the RAM and mounted in fstab
sudo mkdir /etc/sytemd/sleep.conf.d/
sudo cp /etc/systemd/sleep.conf /etc/systemd/sleep.conf.d/
grep -v '^#' /etc/systemd/sleep.conf.d/sleep.conf
[Sleep]
AllowSuspend=yes
AllowHibernation=yes
AllowSuspendThenHibernate=yes
AllowHybridSleep=yes
SuspendState=freeze
HibernateMode=platform
HibernateOnACPower=yes
in Power management selected When sleeping, enter: Hybrid sleep
and used Sleep which is with non-zero consumption (blinking led) w fast resume though login.
For me it’s much ado about nothing. Sorry if this does not pass the scientific test.
I think
sudo cp /etc/systemd/sleep.conf /etc/systemd/sleep.conf.d/
is unnecessary, as sleep.conf is already used.
I have a swap which exceeds my ram size.
Hibernation works. The only issue, when I hibernate, my PC directly restarts and resumes hibernation instead of power off.
As I read in the header of sleep.conf
systemd-analyze cat-config systemd/sleep.conf
tells what is valid. I see the uncommented lines as well.
If I initiate a Hibernate by a shortcut a shutdown is done and does not restart by itself.
Pressing power on Grub appears. Having booted it conpains for swap and does not resume…
journalctl -b 0 | grep -i hibern

Sadly that didin’t help.
[Sleep]
AllowSuspend=yes
AllowHibernation=yes
AllowSuspendThenHibernate=yes
AllowHybridSleep=yes
SuspendState=mem standby freeze
HibernateMode=platform shutdown
#MemorySleepMode=
#HibernateDelaySec=

#SuspendEstimationSec=60min
Also it broke hibernate. It is not resuming anymore. Thus I will comment out the entries.
@huebi ,
With me

I wait 20-30 sec and then only power led is blinking at 0.25 Hz
Restarting with power button stands up less than 5 sec, login screen
and all is as they were left.
Search with / in
journalctl -b 0
for PM: and it shows how much memory was allocated and copied.
So thank ArchWiki hybrid-sleep seems to be working here.

I think it looks fine:

Hibernate works. My only issue is, that when I hibernate it directly restarts instead of power off.
@huebi
I threw away my test Plasma 6.
Reinstalled Mercury online with manual partitioning ext4.
So the swap partition was automatically recognized.
In Power management the only modification:
When sleeping, enter : Hybrid sleep
systemctl hybrid-sleep or a shortcut to Sleep does the same:
in 45 sec the screen is Off and no blinking led on power button (Ideapad)
Pressing any key asks password and in no time I can carry on this post.
