This could explain why it took literally 3 hours to have the first sign of operation from the unit when I received it (I thought the battery or the charger was dead. I was expecting it to come alive after ~30mn).
Chord have had a couple of failures of the over voltage protection, which is used to protect the charger. This has been because people have not been using the supplied charger, and using PSU units with too high a voltage, which then damages the protection circuits. The protection is there for transient events, not constant over voltage.
It sounds to me that the protect circuit has been damaged, so you will need to send it back to your dealer for repair. Do not use other PSU's apart from the supplied charger - there is no benefit in sound quality with using other chargers, and there is a risk of damaging Hugo in using other PSU's.
