What brands and storage capacity is ur nvme?
Keep updated the gnu system: “sudo apt update; sudo apt upgrade” then downgrading e.c version go to ec-v10 test powering/restarting then go to e.c-v9 test again.
check too: “sudo apt install librem-ec-acpi-dkms”
I dont think is a hardware issue but software.
My Gnu Librem-14 work really good here, zero complaints.
