That's OK.

Makes me believe that the eMate isn't charging the battery.

Measure the resistance between the two white wires while the battery
is
disconnected (measure the battery, not on the mainboard). It should be
about 10kOhm at room temperature. Give or take 1-2kOhm.

This is definitely not enough and supports my belief that the eMate
isn't charging.
Normally this is where the charge voltage should be, which must be
about 6V
or so.

Red is positive power, black is negative power, the two white wires
are connected
to a temperature resistor that is in the battery pack.

Check if you can measure the 7.something Volt where the DC jack is
soldered to the
mainboard. It's unlikely that there's a problem there since you would
in all
likeliness not get the green light if there was, but check it anyway.

You DID follow my reset sequence outlined here, didn't you?
