I've had my nikon less then a year and it wont charge via wall charger or computer. I also tried my back up battery and it wont turn on or charge with that battery either.yes the batteries were installed correctly AND I even took out the memory card as I saw some other forums mentioned to do so without any luck. We bought it from best buy about 9 or 10 months ago so I don't think they will do anything about it since I didn't buy insurance on it. UGH. Any other way I can troubleshoot this to get it to work?
