During my swim, my Forerunner 945 suddenly turns off and not restart; watch power was 85%. I tried to press the upper left start button but it doesn't response, and not even charging now. What to do and what's wrong? Thanks.

Thanks, GerardW. I already tried this but it wasn't working.

sorry about that.did you try local customer support? I managed to smash my first watch screen to bits (fell with a bike). Not covered by warranty anymore but got a replacement for much less then the value in the shops.

Sorry for my late reply. Well, I got mine from Garmin online so I am not sure bringing it to any store would fix the issue. I have been busy dealing with my mother's situation in rehab so it just sits at my bookshelf now. I remember there was an article about fix this swimming issue but I can't find it anywhere now. I don't know what to do.

Hi!

I just came across your post and wanted to say I’m experiencing the exact same issue with my Forerunner 955. It suddenly turned off while the battery was not low — it wasn’t exactly 70%, but somewhere around that level — and now it won’t turn on or charge, no matter what I try (holding the light button, charging with different adapters, etc.).

I noticed there was no follow-up on your message, so I was wondering — were you eventually able to fix it? If yes, I’d really appreciate it if you could share what worked for you.

Thanks in advance!
