Is your laptop charger not charging your laptop once you plug it into the wall? The problem is more common than you might think based on your assumptions.

Your laptop’s charger is responsible for supplying oxygen to your gadget. In the absence of it, you would be unable to carry on with your daily tasks as usual. However, occasional negligence and errors can frequently result in the charger or the laptop’s charging abilities malfunctioning, which can be very frustrating.

If that is the case, and you discover that your laptop charger is completely unresponsive, this article will assist you in discussing the best possible remedy. Read here how you can charge your laptop in car easily.

Common Reasons for a Faulty or Malfunctioning Laptop Charger

You will receive an immediate indication of the connection of your laptop charger in the form of a beeping sound or the illumination of a specialized LED incorporated inside the computer. However, what if it doesn’t happen and you discover that your laptop isn’t charging even if you’ve plugged it in?

There could be a number of factors contributing to your fears, including:

  • A problem with the power inlet of your computer
  • The battery and charger are old
  • The battery’s driver is outdated
  • A faulty adapter cable could not be delivering enough power to your laptop

Importance of Testing Your Laptop Charger

Understanding how to test your laptop charger can be useful for ensuring that your device is properly recharging your laptop’s batteries to a functional level. The procedure for testing a laptop charger is essentially the same regardless of the type of charger you are using.

It’s important to remember that not all laptop chargers produce the same amount of current. It’s possible that the adapter in your car charges your laptop at a far slower rate than the one plugged in at your table. Furthermore, if you want to use wireless charging, the process may be even slower.

Even taking into consideration the differences in listed amperage across your chargers, some continue to degrade over time and take longer to complete a charge. It could be caused by a damaged or faulty cable, or it could be caused by a faulty AC adaptor. Finding the fundamental cause of such difficulties, on the other hand, necessitates a significant amount of guesswork and is typically time-consuming.

You’re in luck because a multimeter can assist you in this procedure.

What is a Multimeter?

A multimeter, also known as a volt-ohm meter, is a handheld instrument that may be used to compute electrical voltage, resistance, current amperage, and other variables. It is also used to measure electrical resistance. These devices are available in both digital and analogue forms, and they are useful for a wide range of tasks, including basic checks such as defect detection, battery voltage measurement, and more complex diagnostics.

They are one of the most widely used equipment by electricians for troubleshooting electrical difficulties in wire systems, power supplies, circuits, appliances, and motors. They are also one of the most expensive products available.

Keep in mind that the power supply in your computer turns the alternating current from the wall outlet into a direct current flow, which the laptop’s components can use to power their operations. It is possible to prevent any problems by using a digital multimeter to check the DC voltage output of the power supply. You can also determine whether or not you are using a poor power supply by using a digital multimeter.

Probes can be used to make contact with terminals and cables at any time. It is not recommended that you use your own fingers. Using a binder clip or a stand to secure the terminals or wires through the probes can save you from having to hold them through your hand if your hand is too small to hold them through the probes.

How Can You Use a Multimeter to Test Your Laptop Charger?

Are you interested in learning how to use a multimeter to check the functionality of your laptop charger? The steps you must do are outlined in this section.

However, it is common for the pin within your charging connector to be damaged or deformed, depending on the situation. That could be a contributing factor to charging issues. If you discover that the pin is curved, you can straighten it by using a small screwdriver to straighten it. After that, connect your laptop’s charger to it.

If your laptop is still not charging, follow these steps to get it working again. It is not dangerous to test your laptop charger using a multimeter; but, you run the risk of electrocuting yourself, your family members, or other people while doing so.

If you are not sure in your ability to perform this testing, you should seek the assistance of a professional electrician. You’ll always be able to find one.

During this procedure, we will use a digital multimeter to check the functionality of your laptop charger. So go out and grab yourself a digital multimeter with an auto-ranging capability to test your assumptions.

Your laptop charger is made up of two parts: the main plug, which plugs into the main socket, and two pins on the other end. The other component is the adapter, which has an end plug that connects to your laptop. View here laptops with usb c charging.

1. After that, look at the voltage on the adapter. In this example, we’ll utilize a 19-volt adaptor; however, yours may be different. As AC (alternating current) is sent into your laptop from the main socket, it transforms it to a more sensible DC (direct current) that is fed into your laptop via the USB port on the back of the adapter.
2. If you want to test your adapter, make sure it is completely plugged into the socket and turn it on. After that, insert the pin.
3. Check to see that your leads are plugged into the correct sockets. The black wire is connected to the COM port, while the red lead is connected to the VHz symbols. COM port: If you are still unsure, you can always refer back to your manual.
4. Get your probes ready; the black probes are negative, while the red probes are positive. Make certain that your laptop charger is plugged into the main power outlet once more. Then, using your multimeter, choose the DC signal tab and press the button.
5. Take your adapter pin and carefully insert the red positive conductor inside, making sure it hits the tip of the adapter pin while doing so. Take out your black negative probe and prepare for the next step. Place it on the outside of the edge at the tip of the outside of the edge.
6. Your laptop charger’s voltage will be shown on your multimeter, as you can see in the image below. This is how you test your laptop charger with a voltmeter.
Maintaining your attention, keep in mind that the values on your multimeter will change depending on the output voltage supplied by your laptop charger. For this reason, check the voltage values on your AC adapter first and compare them to the readings from the multimeter listed earlier in this section.

That’s all there is to it! Please accept our sincere thanks for reading this article and for any beneficial information we have supplied. You can complete this activity as efficiently and successfully as possible if you have the necessary tools and skills.
