I recommend you do the bulk of your testing on >= 1.5.  The reason is that
all of those platforms have a command to the EC that will disconnect the
external power input and fake a power loss.  Its used in the manufacturing
tests to do a battery discharge/re-charge test.

Using that feature you can automate your testing and compare your results.

In fact I think you can take the manufacturing battery test script as is,
put it in a loop and run it.  Then you can compare the battery log from the
script with your ACPower results.

In theory it should not as there should be an event that happens any time
the external power state changes.  In practice, I seem to remember that
event delivery isn't 100% and there are various powerd versions with bugs
where on/off events are not matched.
