My N8 is won't turn on or charge

All of a sudden my N8 won’t turn on or charge. It was fine the night before and had plenty of charge. Now it’s just a blank screen. I’ve tried all of the chargers it came with. It has a genuine Nokia battery. I’ve read that some early models had a software issue. Mine was actually swapped for a factory reconditioned model because of all the problems it had.
