Did you end up trying anything yet? Isn't there some requirement for a working battery for it to power on or was that just the power routing through the battery so a corroded one isn't a simple run without it fix?

Does anyone know off hand what polarity that Mac Portable requires? I know that the original was 7.5V @ 1.5A, but not sure of the polarity.
