If the power cord on your computer, vacuum, fridge, or any appliance, has become worn, frayed, or cracked, then you will be pleased to know that you can repair the damage yourself. To make this simple repair, you will need the following materials:
a sharp pair of scissors
a replacement three-pronged plug
a roll of electrical tape
a Phillips-head screwdriver
Follow these simple steps to repair the damage to your power cord:
Step 1: Safely Unplug the Power Cord
You should never use your hand and grab a live electrical cord that has been damaged. If you do this, you could suffer a shock or in a severe case become electrocuted. For this reason, turn off the wall outlet's power at the panel. Once the outlet's power has been turned off, then you can safely unplug your laptop.
Step 2: Cut the End of the Damaged Power Cord
If the entire cord is clearly damaged all the way through, then you should cut the end of the cord directly above the damage. Cut about an inch or so above the visibly damaged area to ensure that all of the possibly damaged wire is cleanly removed.
If the cord was damaged, but the plug is still attached, then you can cut the plug off above the damaged area as instructed above, or if the damage did not enter the electrical wires themselves and is just superficial to the outer plastic coating, then you can wrap the cord with electrical tape to repair it.
Step 3: Remove the Outer Plastic Coating and Insulation
To put on a new plug, you will need to remove some of the outer plastic coating and insulation from the power cord.
Using a very sharp pair of scissors or a sharp knife, carefully cut through only the outer layer of plastic of the electrical cord. Cut back about an inch, and then cut off the plastic and cord insulation until you are left with three inner wires to connect to the replacement plug you purchased.
Step 4: Attach the New Plug and Wrap It with Electrical Tape
Some replacement plugs require that you strip the inner wires of your laptop's cord and wrap them tightly around screws inside of the new plug. Other plugs are made in a way that all you have to do is insert the wires into slots and then screw the slots closed. Check the instructions for the plug you purchased and use them as your guide for this step.
Finally, once you have replaced the plug, then you should wrap the end of the electrical cord and new plug with a few wraps of electrical tape. This will help to keep the wires safely in place. If you have more difficult issues with electrical wiring in your home, contact an electrical repair professional to make sure everything is fixed properly.
