Now, here are the things you need to do if your Forerunner 645 Music no longer powers on…

Force restart your Garmin Forerunner 645 Music. Before anything else, perform the forced restart first as it’s often the most effective solution to this kind of problem.

  1. Hold LIGHT for 15 seconds.
  2. The device turns off.
  3. Hold LIGHT for one second to turn on the device.

If the device actually turns on after this, then that would be the end of the problem. However, there’s no guarantee it won’t happen again but if it does, at least you already know what to do. It would also be best to factory reset your device if this kind of problem keeps on happening.

Charge and do the force restart. It is always possible that the problem is caused by a drained battery which may have also resulted to a system crash. So, connect your device to a power source even if it won’t respond. Then perform the same procedure as above to force restart it while charging.

These procedures are enough to fix a problem like this. However, if the issue continues after this, then it’s time you call support or bring device to a service center.
