If you press the power button and the Bluetooth LED does not flash red, there likely is a battery problem. Here is what you should try.
- Connect the sensor to a known-to-work USB power source as you would to charge the sensor.
⚬ If the Bluetooth LED start flashing red, let the battery charge for a couple of hours and try again.
⚬ If the charging LED immediately goes green, but the sensor still won’t turn on, continue to step 2. - Check to see if the battery is fully connected. Open the unit, disconnect then reconnect the battery.
⚬ If the unit turns on, test the power button to make sure the sensor works as expected.
⚬ If the unit still does not turn on, continue to step 3. - Swap the battery with a working unit to see if the problem follows the battery or stays with the unit.
⚬ If the problem stays with the sensor, the battery is probably not the issue, requiring repair.
⚬ If the problem follows the battery, the battery has likely reached its end of life. - See How do I remove or replace a Go Direct battery? for more information.
