| Ok.

another thing: I changed the current drain from "mA or mWh" to "mAh or mW" in
smartbattery.c but I'm having some doubts:

Are these energy or power measures?
for power measures, the units would be mA/h or mW
for energy measures, the units would be mA or mW.h

so, maybe I changed it wrong... care to comment?

thanks for pointing me at the documentation. actually I would be doing that
because I have some printed information at home. But until then, I must work a
little more or else I'll never be an engineer.
