CHRG led always on

When I power on my board the on led turns on, then after about a second the chrg light turns on and does not turn off (I have it powered by usb and there is nothing else connected). I have also tried double pressing the reset button and that does not work, is there any way to fix this or is my board done for. Just to clarify I have tried multiple usb ports/plugs and multiple computers and it does not show up as a serial device.

Thanks for all help given
