1. You have to run power and ground from the micro USB connector on the Lapdock (left) to the RasPi.
2. You have to run two Data lines (data+ and Data-) from the Lapdock connector to one of the USB ports on the RasPi on the left to use the keyboard, mouse etc. Most of us build a "Y" cable to do this. It has three legs. First leg: A micro USB female end to connect to the Lapdock connector. Second leg: A micro USB male to connect to the RasPi power in. Third leg: A USB "A" male end that has only the Data lines to connect to one of the RasPI USB ports.
3. You have to have an adapter from the Micro HDMI on the right to a full size HDMI to plug into the RasPi.
There HAS to be a signal from the HDMI to use the two ports from the internal hub on the back of the Lapdock.
Edit: you also have to lift the Lapdock top up some or the Lapdock USB ports are dead.
Sorry if this sounds too over simplified but that is the Basics that are needed to get the Lapdock hardware working.
Thanks for the reply,
I used the micro usb only for the data. (I cut the red wire coming from the micro usb). And used one of the USB ports on the back to power the PI, but when I open the lapdock top and still, no power comes to the PI.
I have a female micro to female micro HDMI adapter, and a micro to HDMI cable plugging in the PI. But the lapdock screen never gives any signal.
I will try to get a picture of my setup. I'm just wondering if there is something wrong with the lapdock.
