Hi, Since last week my N900 is not charging with the wall charger, nor with the external battery that Nokia shipped with my phone (Spain), but it does charge when connecting it to my PC. The USB port of the phone seems loose, but I can't understand why the phone charges when connected to the computer and not when connected to the charger. So, I'm not 100% sure it is broken. Maybe it is a software problem. I don't know. What do you think? I guess I should call Nokia support.
