Hey,
I have a forerunner 620 w/ no warranty. Recently, it stopped powering on completely even when plugged in. It does get warm though.
Any ideas on what this could mean? I was thinking it might be a dead battery, but I read somewhere that if it won't power on when on a charger it's not the battery. Is this true? Should I look into getting the battery replaced by a 3rd party for like half the price of a refurb ($50 vs $100).
Thanks
