I have this problem, when i plug in wall charger my n900 does not start to charge but when i plug in my n900 to pc with usb it starts to charge, i have tried 2 different wall chargers and one car charger but it just wont start charging and this has never happened before, it started to do this thing when i updated to pr1.3.

could someone say whats the problem?
