So, I still use my acer extensa 5630... However, there is a port, that turned out to be a docking port. I, having a good use for extra ports and being the cheap guy I am, don't want to buy anything and make an adapter myself. I couldn't find any pinouts. I doubt that the port needs an active dock because it has 64 pins, so it only makes sense that it is passive. If somebody knows anything about the pins, please let me know.
