I have this laptop. Bug happens on S3 suspend, much better on modern
standby (once it took two minutes or so for the touchpad to resume,
every other time it has worked).
Modern suspend does not use much battery. Mine slept for 8:20h last night and
the battery percentage declined from 96% to 94%.
Public bug reported:
The reboot failed with many services that could not stop. I think there
may have been a crash in the network stack.

@olepet I have 14ARE05 too, same symptoms. It seems the hardware is different,

The external monitor problem is probably a well-known gdm3 bug: gdm3
with nvidia modeset=1 stops the nvidia driver from detecting external
monitors (possibly it invokes some wayland features when it shouldn't).
It is not a problem with nvidia-prime or with the kernel. You can fix it
by using
