I’m not 100% clear on this.  Does this mean with this utility installed that you _can_ recharge your rechargeable AAs with the Newton power supply/charger with the AA battery tray in the Newton?  That would be cool if that was possible!

So when having modified this case, to make the Newton believe that it is an original Newton battery. In this case the batteries will be recharged by the Newton.
