I have 2 similar presario laptops and I've used the adaptors interchangeably. Considering also my knowledge of post testing demonstrated here and the finite number of possible physical tests it would mean that they've been eliminated from the suspect list. What I did ask was what other tests there could be on the small circuit board inside- the PSU. And no, the PSU's in the laptops are not interchangeable. They're similar, but not the same model or class.
