System reboots after entering sleep.

I have been using s2Idle for sleep (set as "Window and Linux" sleep mode in the Lenovo bios) and have been experience a lot of power drain. So I have decided to experiment with s3 sleep (set as Linux S3 in bios).

My device enters sleep just fine, and since I have a Thinkpad I can see the red light pulse slowly, also suggesting it is sleeping. But, upon waking, my system goes through the full boot process again: I see the full post screen, and none of my windows are open upon logging in. Here is a snapshot of journalctl:

This never occurred while using S2. My understanding was S3 should just suspend to RAM, and while the wake-up would be slower, it wouldn't require a full reboot. The device is an X1 Extreme Gen 5, so it is rather new hardware.

I am curious if anyone has an idea of what may be occurring.

Thanks.

Re: System reboots after entering sleep.

This is correct.

How do you suspend the system?
Does this also happen if you only sleep for a couple of seconds and immediately wake up?
(You might enter a hybrid sleep, though there's no resume parameter)

acpi.ec_no_wakeups

Drop that.

Is there a parallel windows installation?
Are updates for the firmware/BIOS available for the device?

Re: System reboots after entering sleep.

I use systemd to suspend the system (via the Gnome suspend interface)
This still occurs if its just sleeping for only a few seconds.
I don't have a windows installation.
There aren't any firmware updates.
