If you have a sensor that will not charge when it's plugged in, there are a few things to check.
First, try plugging the sensors into different computers and USB ports, with multiple USB cords and charging cradles to ensure that the sensor itself is experiencing the issue.
If you've determined that the sensor itself is at fault, reset the sensor.
To reset the sensor:
1. Plug the sensor into your computer and navigate to the sensor screen in IMU-Step Desktop
2. Hold down the blue button on the sensor cradle until you see the lights on either side of the sensor flash and then become solid again
3. Wait 1-2 minutes for the sensors to reappear in the download screen
Once the sensor is reset allow the sensor to charge overnight. If the sensor still won't charge, contact us for further troubleshooting.
