Earlier today I got an alert that my watch had low power. I was sitting directly in front of my charger at the time, so I plugged it in immediately. An hour or two later I took the watch off the charger and noticed the screen was off. I attempted to turn the screen on several different ways; holding start/back, holding the light button, and simply holding start, all of which I tried both while the watch was plugged in and while unplugged. I have tried to connect it to Garmin Express but the application couldn’t find my watch and neither could the Garmin Connect app on my phone. The green HR sensor light still turns on if I pass my finger over it, but no other part of the watch will respond.
