My netbook (http://www.laptopspark.com) was charging fine when I was first on it. I accidently pulled it too far but the charger didn't un-attatch from Sony Vaio EA3S1E/L Intel Core i3 370M 2.4GHz 500GB HDD 4GB RAM 14.1" WXGA TFT Laptop (http://www.laptopspark.com/products/Sony-Vaio-EA3S1EL-Intel-Core-i3-370M-24GHz-500GB-HDD-4GB-RAM-141-WXGA-TFT-Laptop-laptop-290.html) or plug. I checked it over and it seems fine, but it's not working when I plug it into the netbook (http://www.laptopspark.com). I have tried various different plug sockets but none seem to work. Does anybody know why this is happening or if I can solve it without buying a new charger?
