910XT is dead, won’t charge or start, can’t reset

Former Member over 5 years ago

I’ve tried holding MODE+PowerON and only PowerOn etc, but the watch won’t start nor charge... is there anything else I can do?

And/or try cleaning the contacts on the back of the watch. Google DC Rainmaker's blog on this process, it's probably 10 years old at this point though still applies.

If you're not able to charge it, then likely it is 100% depleted. First step would be to get it charged. As mentioned, clean the contacts. I used a pencil eraser on mine and that seemed to do the trick. If you can, swap the charging clip with a known working clip and charge with a known working power source. The device could be as old as 9 years old (released in 2011), so It's possible that the battery has reached its end-of-life, as Ii-ion batteries can only last so many charging cycles (~500).
