4 months ago I'm running into this as well (lemp13), only it happens whether or not the unit is plugged in (USB-C is the only supported charging method) or not. It's been intermittant (it fails more than it succeeds). From the kernel message buffer:

When laptop is charging using the barrel connector, resume from hibernate fails with error "Hibernate inconsistent memory map". It works fine when charging with USB-C or when on running on battery.
Steps to reproduce
Connect barrel connector charger, hibernate, power on the laptop again.
Expected behavior
Should see back the opened windows.
Actual behavior
Boots into initial login screen, dmesg shows the hibernate error above.
Additional info
It seems that charging using the barrel connector changes the memory mapping of the firmware after resume from hibernate:
Before hibernate:
After failed resume:
When charger is disconnected, I get consistently the latter mapping.
