Not sure if this is posted anywhere else because I couldn't see any relevant thread from search results (yea, I failed at searching :/). Please let me know if there is one.

I am one of the few lucky ones who is having an N9 that has a faulty LED that wouldn't light up when it is charging/charged. However, I managed to used up all the battery power a few days ago and the phone went off automatically. Then I plug the phone to the charger (the phone is not powered on), and the notification LED started to blink for a couple of seconds until the charging indicator is shown on screen.

Is there anything I can do to fix it? suspecting this is a software problem :/
