Furthermore, to answer the question of why a third prong that doesn't GO
anywhere, be advised that some manufacturers used to make use of a specific
prong of a duplex plug as it's hot or ground return lead. They designed
their inner circuitry accordingly.
That's why the advent of the single wider prong on many duplex plugs in
recent years. Did away with the need for that third prong.

Why they did that...the reasoning behind it, I'm not knowledgeable about,
so that's just a semi-educated guess.

When green, you are charged to the degree that the particular battery can be charge. BUT the MagSafe chargers determine this using very simple chip "brains" and while simple brains tend to be highly reliable, they are not infallible. Still, this seems like the least likely answer that I can think of.

I can also tell you that school IT departments make some pretty bizarre diagnoses. Which is not to say I don't sympathize deeply with those who do this job.

the computers and accessories were handed out in shopping bags.

the one given is a 60 watt charger but this was not used by the tech person. We don't know what she used as she had a few on her desk.

I am going to run the battery down today and then give it a full charge.
