I wonder if anyone else has had their Varia malfunction? Bought mine in '23 and it has worked well until yesterday when it stopped working and wouldn't turn on even though the battery had been fully charged with solid green charging light. I did a hard reset with the power button held for 8 seconds and plugged charger in again with no luck although on a couple occasions it would light up but only while charging (solid green light), unplugged it turned off. Garmin has some sort of exchange program for out of warranty at a price but they don't specify the fee (AI indicates $70 to $90) and I want to use it now rather than send it in so I took it apart not having much to lose since I'd buy another if I couldn't get it to work. Multimeter on the battery terminals read over 4v (3.8v spec battery). When I plugged the battery connector back into the circuit board it went back to working as usual. Not sure what the problem is or was other than guessing that the connection may have been loose. I won't be surprised if it stops working again but I'm hopeful it won't.
