My clip sport is about 2 months old,
Now whenever I plug the clip into a usb port it starts up and then promty returns the low battery message, no matter how long I leave it charging its always displays low battery.
I’ve tried holding power and select to force a restart, no effect.
I’ve tried SDFormatter an OS X app, this used to work whenever I had major league trouble with old sansa clips (x3), often it wouldn’t show up on the desktop, but SDFormatter could see it, a reformat would fix it.
In short neither the OS or SDFormatter recognise the clip sport as connected.
I read somewhere a suggestion of connecting to a mobile phone cable and trying to chage from that. I’ve had a look and none of ours fit.
