Thanks for the reference from the old forum. I have not detected it. Quite on the point.

So, it is possible to conclude that being conected the adapter without batteries inside a Hp-65 or Hp-67, it may cause to make fail not only the SENSE chip and other Card Reader PCB components, but also the indicated cap at the power line in the main PCB, specially if this could be a 6 volts one.
