A laptop charger provides power to the laptop and the battery. Without a correctly functioning charger, the computer will not hold a charge. In some cases it is possible to take the laptop charger apart and make any necessary repairs. Often, the cord on the charger has shorted out and must be fixed. The process of taking apart the charger is straightforward, although the outcome depends on how the charger was built and secured by the manufacturer.

Instructions

  1. 1

    Open the laptop charger by inserting a flathead screwdriver into the trim. Some chargers are glued together, so a knife is needed to separate and open the charger. Depending on the manufacturer, however, a charger may have been designed to be impossible to open.

  2. 2

    Remove all of the cord that is coiled up inside the adaptor. Use wire cutters to carefully cut and remove the plastic cord without cutting the metal wires inside the cord. Check the entire length of the cord to locate the short, which will be visibly damaged or frayed.

  3. 3

    Use the wire cutters to remove the portion of the metal wire that is damaged. Shave both remaining ends of the wire down by half and twist them together to reconnect the wire. Cover the exposed metal with electrical tape to bond and protect the wire.

  4. 4

    Plug the cord into an electrical socket to check if the charger is working correctly. Recoil the cord back into the adaptor and pop both halves back into place. If the charger was glued together, a small amount of glue can be used to secure both of the halves of the adaptor.

  5. 5

    Evaluate the laptop charger if it is still not working correctly. Taking a charger to a laptop technician can be expensive, so purchasing a new charger may be the best option.

Tips and warnings

  • Computer World recommends replacing a laptop cord that is significantly broken or frayed outside of the adaptor because it may become a fire hazard. If there is only a small outer fray that does not directly impact the inner cord, then a layer of silicone sealer can be applied to fix it.
  • Always take care when working on electrical equipment to avoid sustaining serious injuries and burns. If a laptop cord is significantly damaged, replace it to avoid a potential fire hazard.
