Charging Differed

My Clip Jam first refused to turn on, then since it showed up (files could be read) on a PC screen I insisted several times and it started again.
But the first message that showed was “charging differed”.
Even after updating the firmware, there is no possibility to charge the device.
Connection with a PC shows on the screen for a second charging and then becomes linking.
Any remedy to that?
Thks beforehand
