What I am now interested in is understanding a "correct" state of
charge value after having my battery out of the XO for one month.
[When I insert that battery and plug in the AC adapter, the 'power'
light is green, and the software pop-up says 94%. But I notice that
after an hour, the software pop-up *still* says 94%.]
I presume that when I merely "shut down" the XO, and leave it
sitting for two days with the battery still in the case: Then when
I again connect the XO to the AC adapter (and let it charge until
the 'power' light goes from yellow to green), I should be able to
trust that what the software pop-up says is accurate.
But when the software pop-up is between 90-96% (for a previously
out-of-case battery), and despite the AC adapter being plugged in
that value does not increase in an hour -- what ought I to do to
find the "state of charge" ?
