I've looked on Google, Dell, and a few other places to find out what happened to my Ultrabook. The laptop kept saying it was getting no power although it was plugged in and charging (or so it said). Finally it ran out of power, and in the last throws, it would try to power on, then die for lack of power. I bought a new AC Power supply, tested the electrical connections (all at spec), a new battery,,.and all but the motherboard. Here's my question: what is the difference between the Dell xps 9530 nwym9, 43pmm, and r99vn? I'm sure something in the nomenclature is obvious, but I just don't see it.
Aside from the mnotherboard designation questions, has anyone solved the power out question? What lead up t6o this situation what constantly shortened power, although plugged in. Thank you
