Mine did the same thing yesterday. No matter which button I pushed, it would display nothing. I've tried charging it on 3 different charging cords, several times, all without success. That is, until a few minutes ago. As soon as I called Fitbit tech support to look for a solution, I pushed the upper right hand button and the device displayed "0%." When I connected the device to a charger, it decided to take a charge. I felt a bit foolish when the tech support gal picked up my call and asked me how she could help. I had to tell her, "nevermind the device decided to start working right after you answered my call." The **ahem** thing is trying to make me look stupider than I really am, or thought I was. I considered going back to using a sun dial to tell time, but MN is almost always cloudy in the winter. Maybe I should have called Fitbit tech support sooner. Maybe the device started to behave when it figured out that I was going to tattle on it.
