Mar 4 2016 the usb wire color code of four wires inside a usb is just very simple.
Color code white wire black wire blue wire laptop charger.
What are the and ground.
Which one to connect where.
While powered the charger found red wire 19vdc white wire 0vdc black wire in the center pin for feedback to the board.
Normal electricians use black red and white for wiring.
There are three wires in it black white and blue.
I am thinking these are live neutral and ground respectively.

The first adapter the one that broke has three wires black white and red going out which then connect to the laptop charger pin.
White black blue for communication validate adapter and battery power it is best you use a multimeter to check.
Question how to check the laptop charger.
Old wire has blue black white new wire has green gray white.
I assume the hot wire is the yellow with the green stripe.
I just want to put a new electric plug on the end.
After connecting the wires make sure to test the voltage on the plug before inserting to the laptop or you might risk damaging your laptop.
I have an hp laptop adapter but the end going into the laptop is broken.
How do i connect the wires.
I have read that an extra wire is used as some kind of a sensor.
The red wire is marked in the adapter as v.
The problem with your answer is that i have bought a new computer i only need the charger for a short time to get the info off the old computer.
If you have the color red black white and green this post will teach you the corresponding color code for that.
The bad adapter has red white and black the other has blue white and black.
