output hwinfo

On Lenovo X1 Extreme Gen.3 suspend/hibernate to RAM doesn't work properly. 

5.3.18-lp152.63-default
openSUSE Leap 15.2

If I close the cover it suspends/hibernates and starts sleeping, but when I
re-open the cover it does not survive beeing awaked. Instead, it works
$something for half a second and then it powers of completely. After pressing
the power button, it does a complete cold boot.

In rare cases it did survive a suspend and it did awake properly. But only in
very rare cases.

dmesg logs:

systemd-logind: hibernation is restricted; see man kernel_lockdown.7
