How To Test Laptop Charger? [2022]

Laptop chargers are an often overlooked piece of technology. Many people assume that as long as their charger is plugged in, it will work properly and keep their laptop charged. However, this is not always the case, especially when you’re dealing with a faulty power cable or adapter. If your laptop is no longer charging properly – or at all – it’s important to test your charger before taking any further steps.

There are a few different ways that you can test your laptop charger:

Different ways to test your laptop charger

Step1

The first way is to plug the power cable into the wall outlet and then into your laptop. Once it’s plugged in, turn on your laptop and see if the battery indicator light comes on. If it doesn’t, then there may be an issue with your charger.

Step2

The second way to test your charger is to use a multimeter. First, make sure that the multimeter is turned off and then set it to the “DC Volts” setting. Next, take the red lead and touch it to the end of the barrel plug that goes into your laptop. Then, take the black lead and touch it to the other end of the barrel plug. Finally, turn on the multimeter and see what voltage it’s reading. If it’s not reading above 20 volts, then there may be an issue with your charger.

Step 3

If you are still unable to test your laptop charger or if it is not working properly, then you may need to consider replacing the adapter or power cable. There are many different options available online, so be sure to do your research and find one that fits your needs and budget.

Step 4

Check the battery for corrosion, damage, or other issues. If you notice any signs of problems with the battery, then it may also need to be replaced as well.

Step 5

Test your charger with a voltmeter. Set the multimeter to the “DC Volts” setting and touch the red lead to the end of the barrel plug that goes into your laptop. Touch the black lead to the other end of the barrel plug. Turn on the multimeter and see what voltage it’s reading. If it’s not reading above 20 volts, there may be an issue with your charger.

If you have an Energizer battery charger that’s not working, there are a few things you can try to fix the issue.

Check Connections

Make sure that the charger is properly plugged into an outlet and that the cord is securely connected to the charger. If you’re using an extension cord, ensure that it’s a heavy-duty cord rated for the amperage of the charger.

If the charger is defective, it will need to be replaced. Energizer offers a warranty on its chargers, so you may be able to get a replacement for free if the issue is due to a manufacturing defect.
