Hi. I have a Lenovo 3000 N200 and two months ago the plug snapped so I bought another off eBay. The one sent was too powerful for the system (90w not 65w) and as a result the motherboard blew. After that when plugged in even with a correct wattage plug the battery would drain even though the system showed as 'AC Power' and 'Charging'. Our local repair shop has it at the moment in bits but non of his suppliers can locate a motherboard for a 3000 N200. Does anyone know of a location I can order a motherboard from or should I contact Lenovo directly for a repair quote from them? Mnay thanks.
