Remember when I couldn't get DX to communicate with my new lappy? Finally, I got only one usb port to work with it. So.. the Sony guy came in to fix my lappy on site, today, right? New motherboard, new usb ports and both ports with the DX for charging it and communicating. Unbelievable. My Sony is only 3 months old and it needed a new motherboard.
