Can You Repair A Power Adapter For A Hd All-in-one
It's such a common occurrence that you lot've probably experienced information technology firsthand. The power adapter plug that goes into your notebook computer starts to become flaky. You accept to wiggle the cord, twist it into a certain position or put some tension on the cord by folding it under the computer in order to go it to piece of work. Power adapters can price hundreds of dollars to replace, but they tin oft exist repaired for free if y'all already have the necessary materials.
The same thing can happen to the plug on any kind of ability adapter, only it happens most frequently with notebook computer power supplies, especially ones with coaxial cords. This is considering people carry notebook computers and their power adapters with them all the fourth dimension, and the abiding wrapping and unwrapping of the string, combined with the manipulation of the plug, can cause information technology to fail. Information technology'due south non the plug that goes bad on a power adapter, merely the cord itself, or more specifically, the connections between the cord and the plug fail. This happens often to headphones, too, but these are usually incommunicable to set up because of the kind of wire used; fortunately they're inexpensive to supersede.
The photograph higher up shows a typical coaxial power plug. At the factory, the wires coming from the cord are soldered and/or crimped to contacts on the metal portion of the plug, and then a vinyl jacket is molded around the assembly to provide strength and to form a grip. Too much flexing of the cord causes the connections between the plug and cord to neglect inside the molded jacket.
If you have a power adapter that works intermittently, especially when yous jerk the plug, it's more than likely that the wires take asunder from the plug itself or that they're shorting out (touching each other). Either way, the repair is the same. And by the style, you should stop wiggling the plug and either fix information technology or replace the power adapter because wiggling the plug can harm the socket in your notebook computer, and repairing that is a complicated and risky process.
It'southward always best if you lot tin confirm where the problem is before beginning a repair. If you have a volt meter, it's a simple matter to check the output voltage of the plug and see if it fluctuates as you wiggle the cord. If the voltage doesn't fluctuate, the socket in your notebook computer could exist damaged and, over again, repairing that is complicated and risky.
Sometimes the cord can neglect correct where it exits the ability brick. If wiggling the cord there causes problems, at that place's no need to repair the plug. But your only choice might be to replace the ability adapter because you would have to open up upward the adapter to make this repair, and they're not designed to be opened or serviced in any way. If you're aggressive enough, you might exist able to cutting open the power adapter, cutting off the bad part of the cord and solder it back into place. Even though you could do more harm than expert, if the ability adapter isn't working, you've got nix to lose.
If yous've determined that the problem is with the plug, yous take to either replace the plug or repair the electrical connections to it. If you can detect an verbal replacement for the plug, say at Radio Shack™, you might be better off simply clipping the old 1 and soldering on a new one. But be sure to connect positive and negative correctly. Positive is usually the inner sleeve and negative is the outer part of the plug. Earlier you do anything, though, make sure the power adapter is not plugged into an AC outlet.
To repair the erstwhile plug, y'all have to start by cut off the jacket surrounding the contact points, as shown above. You tin can simply slice the jacket downwards its side with a razor blade and skin information technology off or cut the plug off and wiggle the metal role out of the vinyl jacket. Either way, what'southward important is that you non damage the metal part of the plug, which will be reused. What'southward even more important is that y'all don't cut yourself when using a razor. Exist careful! You've been warned.
At present you can cut the backlog wire off the plug and cut the messy terminate off the cord. The plug used in these photos had the inner wire crimped into place—the blank wire is slipped inside the inner sleeve, which is then crimped (crushed) to concur the wire in identify. To become the wire out, information technology'south best to "un-crimp" the sleeve by squeezing it dorsum into a circle with needle-nose pliers. Only don't impairment the sleeve. If the middle wire is soldered in identify you accept to rut it up with a soldering iron and pull it out in one case the old solder is melted. Exist careful what you affect when using a soldering iron. Things go hot. Don't burn yourself. Use pliers or tweezers when needed. The outer negative connection is always soldered and you lot can simply rut upwards the solder and pull off the wire, or apply solder wick, which keeps things neater.
Solder wick is flat braided copper used to remove solder. You simply place it over the old solder and press downwardly on it with a hot soldering iron. The wick will soak up the solder when information technology melts. Then you cutting off the used portion of the wick and throw it abroad. Solder wick, along with solder, soldering irons and other tools you might demand may be purchased at Radio Shack™, hardware stores, and other places that carry electronic parts and repair items.
When you're finished removing the quondam solder and wire from the plug it should wait something like what you see above.
It'south time to gear up the ends of the cord, as shown higher up. Cutting the center wire down to roughly 1/2 inch and strip off about 1/8 inch of the insulator. Twist the outer wire together as shown and cut its length down to nearly one inch. The length of the wires is critical. The centre wire should fit into the plug'south middle sleeve and the outer wire should reach the outer office of the plug where the old length of wire was soldered to information technology.
Next, slip the blank end of the center wire into the inner sleeve and crimp the sleeve to agree it in identify. Yous tin can use the wire-cutting jaws of needle-olfactory organ pliers to practice the crimping, but don't squeeze and so hard that you cut correct through it. You tin solder the heart wire instead, but don't let it go too hot, as the plastic parts of the plug tin can melt, rendering it useless. Now slip a brusk length of heat-shrink tubing over the exposed outer wire and compress it in place with a lighter, leaving at least i/8 inch of the wire bare. This will forestall the outer wire from touching the inner conductor. Yous can employ electrical tape instead of rut-shrink tubing, merely the tubing is much more than efficient. It doesn't accept much heat to compress the tubing; attempt non to burn it.
Now it'south time to solder the outer wire to the outer part of the plug, as shown above. You might demand iii hands, a modest vise or clamp to do this. Work neatly and don't use too much solder, which could create a short between the inner and outer parts of the plug.
All that'south left to do is to slip a larger piece of rut-compress tubing over the plug and its contacts and compress it in place as shown above. The tubing should cover function of the insulation on the cord and the soldered connection on the outer part of the plug.
The tubing stiffens every bit information technology shrinks, providing some forcefulness to the assembly. Even so, it's a good idea to shrink some other layer or two of tubing over the assembly as shown above to provide even greater forcefulness to the repair. If yous have a volt meter, y'all can use it to verify that the ability adapter is now working properly. It should plug right into your computer and work like new.
