How to solder Dell Charger

[jakov]

I pulled the cable and the plug broke off. A message 'plugged in not chargin' was popping out for a while and it turns out all three wires were broken. I found on the internet that one extra wire is communication between the laptop and the adapter, something like adapter identification. Does somebody know how to connect the wires and what would happen if I connected it wrong because im to affraid to try? The adapter is Dell 1900-32D2 and laptop Inspiron 5521.

I know that the blue wire (ID) goes in the middle but i'm not sure about the other two, My guess by the length of the wires is the black one goes on the outher tube and the white on the inner but isn't the black one supposed to be power. This also confused me http/www.laptop-junction.com/toast/content/dell-ac-power-adapter-power-plug.

If you get it wrong you could fry your board. Buy one off of ebay for $10.00

The white wire is usually the supply voltage + and black is usually the ground - wire. According to the pics, the black would be on the outer tube and the white on the inner. You may be able to verify by checking the polarity image on the power supply or laptop, they usually show if the + is on the inner or outer. http/jbryant.eu/images/Polarity.jpg

I believe most electronics have the positive in the middle. If you are unsure though, I would take the advise above and just buy a new one. You don't want to risk the death of your laptop

Don't solder an old cable together. Especially not a charging cable. This is very seriously a bad idea, and there's a very high risk of a fire hazard, even if soldered together correctly. Go here and find a new one:

How sure are you exactly? I know a couple of people who do electrics but just didn't want to mess with such expensive things, not because of your reasons, but because they were affraid of mixing up the wires and doing damage to the mobo like reedo_43 said.

Pretty sure, indeed. Messing with a broken power supply is always bad news, even if you're experienced in fixing power cords. Soldering a cord for something like a lamp is far different than doing it for a computer. It's up to you either way, but I know without a shadow of doubt that even the most hardened people I know are more likely to buy a new charger, myself included. PC's are often very expensive. Even worse to replace due to human error. And so are homes.
