Hey Ryan, sorry to hear about your Nano. Sounds like a dead battery to me. Your best bet would probably be to [guide|1161|replace the battery] with one of our [product|IF141-002|battery replacement kits]. Unfortunately, replacing the battery requires some soldering, but if you're game, give it a shot! What better way to learn, right?
Hope this helps! Good luck, and let us know how it goes.
