Does anyone know the size of the power cord for the Aspire One D250-1389? I need to know the size of the part that plugs into the computer. I bought a replacement cord on ebay (after my puppy chewed up the original), but I didn't realize that there are different models of the Aspire One D250 that use slightly different size cords. The seller now wants to know what size the connector is, and I can't find it anywhere. The one he sent me is too loose and I have to wiggle it around for it to work. Thanks for any help!
