I've had my DPT-S1 for a bit over a year (Since July 2015) and have been extremely happy with it. However, since yesterday it seems to have stopped charging. When I plug it into the wall, the red charging light does not come on, the battery remains at critical and the device is not usable. I have tried various cables and adaptors and the result is the same.
Has anyone had problems with the battery becoming unusable in this system, or had any similar charging issues? This seems to have come on very suddenly.
Have you tried charging it on a computer? Test if it will charge on a computer. If still unresolved, you may reset the unit by pressing the RESET button with a small pin or clip.

That was great, thanks very much. Indeed, charging from a computer worked, and then switching back to charging from the usual USB power adapter now works, so it seems to have remembered how to charge itself.
