Common causes of Power Adapter problems

Power adapters are responsible for supplying your laptop with the necessary power to operate. They convert AC electrical current from the wall outlet into DC electrical current your laptop can use.

Below are some of the common reasons why power adapter malfunctions:

Short circuits and Frayed Cords

One of the most apparent causes of power adapter failure is physical damage to the cord. Over time, the wires within the cord can fray, and the outer insulation can wear away. This exposure can lead to short circuiting, which can cause permanent damage to your adapter.


With consistent use, power adapters generate a lot of heat which could lead to overheating. The heat strains the electronics inside the adapter, causing them to degrade over time and ultimately resulting in it not working.

Poor Design

Not all power adapters are built the same. Some adapters may experience design flaws such as poor ventilation, weak components, or a lack of adequate protection from electrical surges. These design flaws can cause distortion in the electrical communication between the adapter and your laptop.

Tips for Troubleshooting Power Adapter Issues

When your laptop power adapter stops working, it doesn't necessarily mean it is beyond repair. Before you take any action, perform these quick troubleshooting checks:

Check for Organizational Settings

Make sure your organization settings are set correctly before concluding that there is a power adapter issue. Low battery settings or sleep mode could be the cause of the perceived power adapter problem.

Check Your Outlet

Plug in another device into the power outlet, if it doesn't work with any other device, there might be an issue with the outlet itself.

Check Adapter Output

Verify that your power adapter is supplying your laptop with the right voltage output. One way to do this is to find the specifications label on your power adapter. The label should display output voltage (in volts), current (in amperes) and power (in watts). Cross-check these measurements with the manufacturer's specifications, which should be listed in your laptop manual.

If none of these quick troubleshooting fixes work, you can try repairing your power adapter yourself or visit a technician.

How to Repair Power Adapter

If you're someone who's comfortable tinkering with small electrical components, you can try fixing your power adapter on your own.

Equipment needed for Power Adapter Repair

For this task, you'll need the following equipment:

  • Soldering Iron
  • Thermal paste
  • Pliers
  • Wire cutters

Repairing the damaged cord

The most common issue with power adapters is a frayed or torn power cord. If the cord is beyond repair, you'll need to replace it. Follow these steps to repair the damaged cord:

Turn off and unplug the adapter.Cut off the damaged area of the cord.Use the wire cutters to strip approximately an inch of insulation off the newly cut wires.Now strip the insulation inside the adapter to expose the end of the wires.Twist together the exposed ends of the wires inside the adapter, and repeat this to the exposed wire on the cord.Use solder and a soldering iron to connect both pieces of twisted wires.Wrap the soldered joint with electrical tape.

Replace the fuse

If your power adapter appears dead, the fuse could be the problem. The fuse is located within the adapter, present to protect it from electrical surges and fluctuations. Follow the steps to replace the fuse:

Find the fuse inside the adapter.Using a fuse removal tool, remove the fuse from the circuit board.Replace the old fuse with a brand new fuse with the same amperage and voltage specifications.Put the adapter cover back on with all the screws.

Thermal Paste Replacement

A Power adapter’s internal components can overheat if thermal paste dries up (thermal paste is a thermally conductive substance that is used to transfer heat between two surfaces). The good news is that thermal paste replacement is also easy. Follow these instructions:

Unscrew the back of the adapter using a screwdriver.Locate the heat sink and confirm that thermal paste has dried up. It will look white and crumbly.Clean the dried out thermal paste with a clean cloth or a soft brush.Apply a small amount of new thermal paste (about the size of a pea) in the center of the chip, and spread it out with the edge of a credit card.Tighten all the screws on the adapter cover.

Prevention of Power Adapter damage

Although power adapters are designed to last long, there are still ways to extend their life. Here are some tips for preserving your power adapter:

Avoid twisting and bending the cord around your adapter.Do not expose your adapter to moisture or extreme temperatures.Invest in a surge protector or battery backup to protect your adapter from electrical fluctuations.When in transit, try to keep the adapter separate from the laptop.


There's no need to panic when your laptop power adapter stops working. Performing quick troubleshooting checks can help you determine the source of the problem. You can also repair the power adapter yourself or take it to a technician for repair. Remember that power adapters are integral parts of your laptop, and a little bit of care can go a long way in preventing it from getting damaged.
