Tried that. Not a peep, which is interesting because, I would have expected
that test to work. I tried it
with and without power on the Pi.
Even if it had worked, I would have queried the result. Without the SD Card,
the Pi is only running the
microcode that gets it booted and services the needed ports such as the USB.
It wouldn't necessarily
mean that the Pi could complete the boot.

Absolutely. I originally only had an old Blackberry PSU/charger, (which works
fine on the Pi 2), so I
ordered a 'proper' Raspberry Pi PSU from the Swag Store. Exactly the same..

:-) We had this discussion a few weeks ago. It was me who was adamant that
you can't just pull the plug.
