Along with cleaning the connectors, try this.
With the watch not connected, hold three buttons down (light, down and start buttons) for 15-20 seconds and try charging again.
I just finished chatting with Erica from Garmin Support Centre. The chat took less than 10 minutes and resulted in them sending me a refurbished watch, and I'll send in the defective one when I receive…
Mine wouldn't charge at ALL. I did your trick thinking it wouldn't work as there was no power left but it worked. Thank you!
This fix worked. Thanks very much.
Had the same problem, cleaned the connectors, tried the 3 button approach, but in the end I fixed it by screwing off the back plate, looking at the innards, pushing the back plate back on screwing it back tightly. Connected the charger cable and presto, it started charging again. I must have reset or realigned something by taking off the back plate. Anyhow, hope this helps someone. Don't do this if you're still in the warranty period, of course.
this one works perfectly, and when it turns on, was 89% charged. why does it happened?
i just did the 3 button hold trick and it also worked. amazing stuff. Thanks!!
which are the 3 buttons? earlier in the post it say, light, down and the on button, isn't the light button also the on button? ?
Two left hand buttons and top right..
This was my solution. Somehow the watch has decided to not work with a wall adapter, but likes the PC connection.
The instructions given within this thread that are working, is a hard reset process. (There is additional conversation in this thread using 3 buttons but 2 of those 3 buttons are being ignored with how the steps are described. The only button making an impact on the core issue of this thread is using the top left button. AKA: the top left button is also the backlight button, power button, and long hold to see the controls menu.)
Please try the following:
- With your watch unplugged, hold down the top left button for 30 seconds.
If your watch did not turn on, plug your watch in to charge it. Give 15-20 seconds to see if your watch responds and shows being charged. If there is no watch response, proceed to the next step.
- With your watch plugged in to charge, hold down the top left button again for 30 seconds.
If your watch is going to recover and the issue is not a failure of the lithium-ion battery, the above two steps work quite frequently and will resolve a Fenix 5 Plus series watch when it is not powering on or charging.
Could someone from Garmin comment which software crashes and is responsible for the non charging?
Maybe worth investigating and fixing the software?
Haha sure, they've probably got 3 teams working on it around the clock.
Sorry, seriously, they don't care about products that are 5 or more years old.
In short, don't expect firmware updates anymore.
