splicing different color charger wires

post #1 of 13
Thread Starter 
I have a charger for a laptop in which the wires are bent/broken.
I am attempting to splice the two different parts together. The charger wire has a white wire for hot and a mesh wire for ground. I am sure of this.
The input cord to the laptop has two wires but are colored blue and brown. I am trying to determine which is hot and which is ground. Any ideas?

Splicing chargers is not a good idea, usually doesn't work out well for all parties involved smile.gif Usually brown would be the negative from what I've dealt with.

All I can say. Is live is most often brown. And neutral is then blue!

But then, who knows if they bothered following what is normal???

edit ^^^^^


I'd wait for more input on this, if I were you!

I have done this before with no problems. Just putting a new end on it. I am going to connect them and check the polarity with a voltmeter and try to figure out which is which.
On the dongle which inserts into the laptop. The outside is the ground on the plug and the inside is hot, is this correct?

Is the interior pin the hot on the laptop power input hot or ground.
The out side part of the connector is the ground isn't it?
Actually I figured out the interior part of the connector is hot and the outside is ground.
