Also, if anyone can shed some light on this, I’m trying to help with the Expansion Bay Battery (Link 1), and aside from the EC issue, I’m trying to figure out what would be the best connection and what pinout it would all need to be.
I know we’d need to connect to pins 41-46 for V_ADP_GPU for power as shown in Link 2 and the image. For the ground (GND_ADP_GPU) pins, I think that’s 47-51. I believe I could make a small connector that piggybacks off of the current interposer connection by sandwiching itself between the interposer and mainboard. An easier and more physically stable piggyback connection would be to connect to the 8 pins on the expansion bay itself that the interposer attaches to, but I can’t find any documentation as to what that pinout is, or if that’s feasible, or even if there’s any multiplexing going on (which I’m fairly sure there isn’t). Does anyone know if there’s any documentation for that part?
Does anyone have any thoughts or input? Anything helps, I’m still learning a lot =D
