You can try the following:

1. Force to Mass Storage -
Turn unit off. Hold the lap/reset button while plugging the unit into the USB. Continue holding the lap/reset for 30 seconds and the unit should go to mass storage.

2. Non-prompted Non-Vol Clear – Clears NV and deletes all FIT files including Activities, Courses, Workouts.
1. Hold Lap/Reset and Start/Stop
2. Press and release the power button
3. Continue to hold only Lap/Reset and Start/Stop
4. Release Lap/Reset and Start/Stop when the Garmin Logo is cleared
5. The unit will restart and clear nonvol.

---

If the power button still won't work then the power button is likely defective and the device will need to be returned to Garmin for repair.
