Charging and 770 shuts down?

[nowen]

Hi All,

This just started happening on my 770. When I go to charge it, it shuts down after about 30 seconds. I start charging with unit turned off as I normally do and screen shows it is charging. Then it just shuts down. It used to stay on indicating charging and would show when done. Screen would stay on the whole time. I did try and remove and replace the battery but it is still doing it.

Any ideas?

Thanks for any replies!
