Repair connector on HP charger
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
Is this a good question?

I edited the post adding a picture of the charger. From what I found on google (searching for HU10436-15104 at the top right corner), i found the model number : 843319-002

I did some voltage measurement and I got this :
White - Blue = 2.9V
White - Black = 0V
Black - Blue = 2.9V
And resistance between Black - Earth (from power plug) = 1Mohm
So Black may be the ground wire, but it seemed stranged that it wasn't connected to the casing of the USB C connector itself.
So White should be GND, blue VBUS and black Earth ?
I don't know also I my laptop will support if I wire this the wrong way, so I'm afraid to test this on my laptop, but I don't know what else I can try this on.
