With my MP100, I have often reversed the polarity. I have used
a selfmade Powersupply and never checked the polarity. Just plugged
it in and then I have looked if it is charging the batteries.
If not I have changed the polarity. The Powersupply was short-circuit-proofed
an the Output Voltage was the same with an open circuit or the Newton
plugged in.
This not a guide, it is only my answer for the question, what happens
if I change the polarity of the poweradapter.
