I did some tests.


Opening the lid or pressing keyboard buttons (e.g. shift) is exactly the same
as closing the lid. Also varying it's behavior on the state of
  /sys/devices/platform/i8042/serio0/power/wakeup


And unplugging the AC power also shows the same behavior.
If
  /sys/devices/LNXSYSTM:00/LNXSYBUS:00/ACPI0003:00/power_supply/AC/power/wakeup
is set to enabled, the notebook fully wakes.
If it's set to disabled, the notebook just stops the "deepest state" of sleep.
(notebook can be fully woken by pressing the power button)

Note:
The EliteBook 845 G8 has two power sockets. A classical one and an USB-C port.
But the wakeup behavior is the equal for both.
