Changing USB Type-C connector
My Hp Chromebook Type-C charger stopped working after a hard pull on the cable. I tore apart the connector and found out the cable just beneath the connector is damaged. I got a new connector but am confused which wire to connect where.
Charger cable has 3 wires (White, Blue, Black) and the connector has 4 connection pads (G, D+, D-, V). I checked voltage between all wires and got:
- White - Blue = 2.9V
- White - Black = 0V
- Black - Blue = 2.9V
Make matter even more confusing the original connector has nine pins (yes not eight), five pins on 'top' (A1, A4, A8, A9, A12) and four pins on the 'bottom' side (B1, B4, B9, B12). I believe A8 is extra and does not do anything but who knows...
If you understand this please help me determine which wire should be soldered on which pad.
Here is a related question I found with similar charger with similar configuration.
Repair connector on HP charger
Это хороший вопрос?
@dadibrokeit take a look at this one. Three wire circuit would lead me to think pos, ground and signal to actually increase to charging voltage. I was thinking something like Qualcomm Quick charge 2.0......
@omi236 when you measured the voltage you did have your meter on VDC not VAC correct? Just making sure we are all on the same page here ;-)
@oldturkey03 yes it was on VDC. I posted this same question on stockexchange and somebody told me that the connector has a chip inside and Hp is using a custom power delivery solution, not a standard one.

@omi236 yes, HP started doing weird things with their power supplies a few years ago. It was to a point that their equipment would not accept third party power supplies due to the ID required by that IC. Now back to figuring out how to solder the connector
