My laptop has not been taking any power from the AC adaptor, and therefore will not turn on. It has a smell of electrical burning when the AC adapter is connected. I sent it to a repair shop who told me they have resoldered the DC jack but this has not fixed the problem. They reckon that the problem is a fault in a power connector card that connects from the DC jack (presumably to the mainboard via a cable?).
My question is, does anyone have any information about these connector components? The repair technician says he can't find a replacement component and has recommended buying a second hand laptop of the same model to take the component from (sounds too expensive for me). He also mentioned that the card is around 2 inches square, and had 3 USB sockets(?) on it.
Any information on this component, or where I can find a replacement would be much appreciated.
