How to troubleshoot a laptop charger.

  • Step 1 Wrap your charger's exposed wiring with electrical tape before proceeding. This will help to prevent any kind of electrical hazard or further damage.
  • Step 2 Push the wire next to the charger base (the connecting tip near the laptop end) side to side to see if you can get a current to connect. This is a temporary solution, but it can help you salvage your files so that you can work with them on a different computer.
  • Step 3 Make sure that it isn't a battery problem. Many laptop owners believe their charger is the problem when their battery is charging. Laptop batteries generally begin to lose the ability to hold a charge after two to three years of heavy usage. Try removing your laptop battery. If the computer still runs, the charger is not the problem.
  • Step 4 Check to see if the issue lies in your computer. You can do this by testing out an alternate charger on the laptop--if the charger still does not work, it's an internal laptop issue. For this kind of power system problem, you will probably have to send your computer to its manufacturer rather than a local repair shop.
  • Step 5 Replace your charger. A replacement charger is usually easy to find and quite affordable. Instead of going to a local electronics retailer where universal chargers can cost $100 or more, look online for your specific model's charger. Some chargers can be purchased for as little as $5

    if wiring harness melts together does that make it bad or can i seperate wires and tape up


    It is bad, you want to replace these wires to prevent further issues. Taping with electrical tape will eventually cause more issues. You need these wires insulated in the proper material.

    How do I replace the power cord on an electrolux 8502A vacuum cleaner?


    1 Unplug the vacuum and remove all accessories such as extensions and brushes. Open the vacuum's outer casing to get at the end of the power cord. Exactly how you will do this depends on the model of vacuum. Generally it simply involves the removal of two to three Phillips-head screws.
    2 Follow the power cord to the two connections at the vacuum's motor. Unfasten any clips or holding bracket and disconnect the cord from the motor. Sometimes this can be accomplished by unscrewing two connection screws, other times the cord is soldered directly to the motor. If this is the case use wire cutters and cut the cord about 4 inches from the motor to give room for splicing on a new cord.
    3 Insert the new power cord into the vacuum. Follow the exact same path as the old one. If there were any brackets or clips that held the old cord in place inside the vacuum or out use them on the new cord.
    4 Tie a knot in the cord on the inside of the vacuum casing so that it will not accidentally be pulled out of the motor once it is in use.
    5 Connect the new cord to the motor in the same fashion as the old one. With wire strippers take off about 1 inch of insulation from the new cord to expose the two wires. Either wrap them around the connection posts and re-screw, or twist the new cord wires around the 4-inch remnants of the old cord and seal all exposed wire and connections with electrical tape.
    6 Replace the vacuum's casing in reverse order from how you removed it. Plug in the vacuum to test.

    The puppy chewed the cord of our chi. Can I find a replacement cord and repair it myself?


    Depending on where your tear is, you can follow just a few steps to help you out. If your tear is a couple inches from either end (like in the middle or close to it) all you need to do is cut out the part that is torn. Once that is done, carefully cut some of the outer plastic back (so that it reveals the actual wires on the inside). Make sure you take that step slow, as to not cut all the way through, just cut through the outer layer. After that, twist the metal wires on the inside together, then cover the exposed metal wires with electrical tape (be generous with the tape so you don't shock yourself in the future. Wrap around 3 to 4+ times)
