Subject: Re: firmware powermgmt.h,1.1,1.2

Re: firmware powermgmt.h,1.1,1.2

Can some kind person explain how the charging mechanism works on the JB
please? the way I understand it is that it always runs off the battaries,
and when it is charging, it charges the battaries at the same time, but not
as fast as using it discharges it. is this correct?

what is meant by charging in discharge and charge?

finally, the new 6 hour max charge time, does that get reset if you pull the
plug, and re-insert it?

many thanks
g
