Fitbit doesn’t show anything but an exclamation mark. When off the charge port it is dark.

The exclamation mark usually means one of two things. You either waited too long to recharge your Charge and the battery is fully depleted. Or else an error occurred during a firmware update, in which case restarting your Charge and leaving it plugged in afterwards will cause the update to resume and complete. How to Reset : Press the button on the charging cable 3 times within 8 seconds, briefly pausing between presses. The button is on the end of the charging cable that is plugged into the computer. 8 seconds after the first button press, the Fitbit logo appears on the tracker’s display. This indicates that it has restarted.
