My Vaio Duo 11 fell onto the floor. Unfortunately it landed on the DC input side. When I checked the internal battery will not charge. And I think the DC input broke as I opened it up and see the DC input board was bit loose. At the moment I can only use the laptop using sheet battery, it only lasts 1-1.5 hours usage. And I have to take the sheet battery off for recharging (inefficient process) . I wonder if you could tell me where I could buy the Sony Vaio Duo 11 DC input board from? Thank you
