Hi, The connector (USB-C) on my HP charger needs to be replaced. So I got a cable to cut it in half and solder the wires on this new cable’s wires. The HP charger has no shielding and 3 wires : white, black and (thin) blue I checked some pinouts for USB-C on the web and I would think the signals are the following : white is gnd ; black is vbus ; blue is cc But then on my other cable, there’s only 2 wires. So my questions : Are the signals I determined corrects ? Should I get another cable with 3 wires in ? Edit. Charger picture
So your trying to splice in a piece of cable that you’ll solder on both ends…one side to the existing USB-C (male) connector and the other back into the 3 wire cable going into the power brick? For sure you’ll have to match up the number and size of each conductor. According to some online literature, we are looking at USB-C Power Delivery (PD). The Red wire is your VCC, the blue is CC (control) and the Black is the Gnd. The CC wire allows for signaling if the voltage needs to change for the sink (load…your laptop, in this case).
Hello @esseivan I have a similar charger and have exact same issue. I am getting same 2.9v reading between black - blue and white - blue. I want to change the type c connector but unable to figure out which wire to connect with which pad. There are three cables but the connector has 4 pads (G, D+, D-, V), please help
