At the end that plugs into the laptop there are 3 holes. In my charger cable, only two of the three holes actually have pins in them. I know it is not the original charger and wonder if it is missing a prong, causing the battery not to charge. Does anyone know how many of the 3 holes should have pins?
Sorry I hadn't come abck to look at this... I have not seen a charger like this at all and I am guessing that you must be running on the European electrical system (I know big stretch given your sn) and I have already stated that I am piss poor at answering questions on your electronics as I know nothing from the wall plug to the computer on your wiring set ups "across the pond". My suggestion would be to jump on e-bay and see if you can buy a used one cheap.
There should be 3 pins at the DC power jack on the laptop itself and 3 holes in the business end of the charger. No one has made a charger that works on these units with less than 3 holes on the charger. I'll look at a CPi I've got on the scrap heap to be sure.
