How To Test Laptop Charger -[ Top 03 Easy Methods]

How To Test Laptop Charger? Easy Methods

  1. Be sure that the charger is plugged into a working outlet and getting power.
  2. Try to run the laptop from the laptop charger only; if it will not run off the charger alone then the charger is faulty or no longer any good.
  3. Try charging your laptop with the laptop powered off.

Is your laptop charger not charging your laptop once you plug it into the wall? Unfortunately, there’s no reason to panic. The problem is common and has a relatively easy fix when you know where to look for the issues.

Your laptop’s charger is responsible for supplying adequate oxygen for your gadget. Without it, you wouldn’t be able to complete daily tasks like sending emails or browsing social media sites.

However, occasionally neglecting this essential piece of equipment can frequently lead to malfunctions and disappointment as a result because it simply won’t produce enough power to juice up your electronic.

If your laptop charger isn’t working, this post will help you find the best way to charge your laptop in a car.

Common Reasons for a Faulty or Malfunctioning Laptop Charger

Your laptop battery may appear to be working fine when you check it the first time, but eventually something might happen.

If it doesn’t charge or only charges partially even after plugging into a power outlet continuously for a long time, then something may have happened to your original battery as well and you need to get it replaced as soon as possible.

There are a number of different factors that contribute 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  • The battery’s driver is outdated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

Checking your laptop charger helps you make sure that you won’t run out of juice during a study session. Knowing how to check your charger isn’t too difficult, but if the technology behind it is too overwhelming don’t worry, we’ve still got you covered.

It’s important to keep in mind 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 pace than the one plugged in at your table. Furthermore, if you want to use wireless charging, the process may be even slower.

Even considering the variances in amperage for your chargers, some continue to degrade over time and might take longer to charge.

This could be caused by a damaged or faulty cable, or it could be caused by a faulty ac adaptor. It may seem like guesswork, but finding the real cause of these difficulties takes significant time.

You’re in luck because a multimeter will assist you in this process.

What is a Multimeter?

A multimeter is a handheld device used to measure voltage, current, and resistance in electronic circuitry. Not only do they count those values but they also display them as well.

These devices are available both in digital and analog forms and may be useful for basic checks such as defect detection, battery voltage measurement, or more complex diagnostics.

Drill bits are very large in diameter. They can be hard to use only with strength, and instead of that people use drill bits with a hand-powered portable drill mechanism known as an electric drill.

Keep in mind that the power supply in your computer turns the alternating current from the wall outlet into direct current for the computer to use.

This can be helpful for preventing any problems and figuring out which of your power supplies are faulty. You can go about this with digital multimeter to check the DC voltage output of any power supply that is being used.

Probes can be used to make terminal and cables contact with at any time. It is not recommended that you use your own fingers.

Using a binder clip or 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 for such tasks.

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

Are you interested in learn how to check the functionality of your laptop charger? The steps you must take are outlined in this section.

However, if your laptop charger’s pin gets damaged or mangled, you can easily fix this minor glitch by straightening it out with the help of a small screwdriver and then reconnecting your laptop’s charging connector.

You can resolve charging issues in a variety of ways. We recommend doing some research first to see if any changes need to happen on your computer.

Before you perform any troubleshooting yourself, we also recommend checking other areas of the house where your charger may be plugged into something else or simply trying a new adapter in case the problem lies with it.

During this procedure, we will use a digital multimeter to test the functionality of your laptop charger.

Go out and grab yourself a digital multimeter with an auto-ranging capability to test your assumptions regarding the functionality of your laptop charger.

When testing your AC adapter/charger, remove the battery from your laptop. The voltage you’ll see on a good charger will be 19 volts and an indication of how reliably it’s sending power to your battery over time.

If that number gets too high to a point where you can smell something burning, then chances are your laptop needs a replacement. You can usually find the model number written in silver near the bottom of the adaptor or charger itself.

Get your probes out; the black ones are going to be used for negative voltage measurements and the red ones for positive ones. Ensure that your laptop charger cord is securely plugged into a main source of power, then turn it back on by pressing and holding in the M key on your keyboard.

Check the voltage values on your adapter with a voltmeter. In order to do this, you must first connect the voltage meter across the “+” and “−” inputs on your laptop power supply as shown in figure #3 of the accompanying document.

That’s all there is to it! Thank you for reading this article and for any great ideas or useful information we have provided. You have the potential to complete this activity as successfully as possible with the right set of tools and skills.
