There is a thread discussing this problem. Here is my summary of the N900 not recognizing the charger: I can reproduce the problem repeatedly if I plug in my cable very slowly. The cable has to be inserted with some appreciable speed. If you are too careful the phone does not recognize the charger. Another way N900 does not recognize the charger is when I plug and unplug my charger quickly, about > 3 times/minute.
