In the past I have been unable to turn on my Garmin Edge after removing it from the charging source. This is how I sorted it out
For some reason, your device may have temporarily locked up. In order to “wake it up”:
- Connect the unit to the available power source
- Press reset and mode for 3 seconds and then release. Once you have done this please attempt to power the device on.
- Allow the unit to charge briefly (15 to 30 minutes), and it should then be ready for use.
