This seems a little far fetched to me. If the Duo can power the termination
sufficiently on Battery power, the the 2xx series AC Adapter should work
just fine. The battery only provides enough juice to run the machine, while
the AC adapter provides enought to run the machine **and** charge the
battery. Maybe there is a loose connection, a short to the case stiffener,
or a lack of contact with the same stiffener.
Unfortunately, I cannot recommend a specific course of action, but I have
serious doubts that it is the AC adapter.
