My vivosport watch was working fine earlier today but now it's just a black screen with no green light on the back and won't take a charge.
History: I last fully charged it Friday (2/26/21) afternoon. I think it was about 40% battery when I started charging.
Today (Sunday 2/28/21) I remember using it for the time about 12:45pm today. Around 3pm today I noticed the screen was black. I plugged into the charger for over an hour but that didn't help.
Using a USB tester, I can see that it's not pulling a charge when plugged into a USB wall charger.
I downloaded the Garmin Express software on a Windows 10 laptop this evening but it can't find the device. I suspect this is because the device isn't powered on.
I've tried using a different Garmin USB charging cord and cleaning the contacts.
Background:
The watch was purchased from a REI store on 11/18/18. The band on that watch broke last spring and I submitted it for exchange (per the Garmin website) on 5/15/20. I think the watch Garmin sent me in return was a brand new one.
Thank you for any suggestions.
