Why My Laptop Charger Overheated And Stopped Working?

Do you want to know why your laptop charger overheated and stopped working? Does the charging of your laptop cause it to overheat? There might be a variety of factors at play here. With correct diagnosis, this is usually a problem that may be resolved quickly.

How hot is your laptop’s power supply? Not a good omen, this.

Make sure your laptop power adapter has enough of room to breathe to prevent it from overheating. When using a laptop, unplug it from time to time so the power cable doesn’t become damaged.

Always unplug your gadget while not in use. This article discusses the common causes of laptop charger overheating and how to resolve the issue.

Laptop Charger Overheated And Stopped Working

Firstly, it’s worth noting that the charging process for any laptop can cause the charger itself to become rather warm.

This is a natural phenomenon caused by the dissipation of energy in the form of heat throughout the course of regular operation of your adapter as it transmits power from the wall outlet to your laptop or Macbook.

This is because the charging process is not completely effective, and some heat is generated during the transfer of electricity through your power cable.

However, a charger can overheat and become unpleasant to the touch depending on numerous variables; this is a major warning flag.

This might lead to a number of catastrophic problems, including, in the worst instance, physical harm to the adapter, laptop, or person.

How To Fix A Laptop Charger Overheating?

Change Your Performance Management Settings

It’s normal for a laptop to get a touch too hot if you’re using it for an activity that requires a lot of processing power, like design, modelling, or gaming.

Nonetheless, this may have an effect on the charger as well in the long term, especially if the adapter has trouble supplying the laptop with adequate voltage to maintain the device’s performance and battery at a stable level.

One possible solution is to adjust the power settings on the system, particularly while running power-intensive programmes that make heavy use of the graphics card.

When using Windows, you may lessen the pressure on your laptop by adjusting the performance plan and maximum CPU state under the System > Power & Sleep settings.

However, if your Mac’s charger is becoming too hot, this option may not be available, since some models lack the ability to adjust the CPU settings.

Check If You’re Using A Correct Charger

Did you know that not all chargers are legitimate even though they appear to charge your laptop even if they fit into its connector (often USB-C these days)?

Using an adapter with a lower voltage or current rating than what your Windows laptop or Macbook requires can force your charger to work harder and get hotter than it needs to.

If the power adapter’s voltage and current rating are lower than the laptop’s requirements, the device may soon overheat, which might damage the adapter or the power supply’s circuits.

Therefore, it is always recommended to contact the laptop’s official retailer or manufacturer for assistance or a replacement charger.

Check Your Charger’s Surroundings

To begin, it’s possible that the problem isn’t technological but rather weather-related. Do you tend to forget where you put your charger? Could you put it near a heater? Is it a warm blanket or maybe some clothing?

A laptop or Mac charger’s temperature can be significantly raised under such conditions.


If the adapter for your laptop or Mac is getting too hot, you may try placing it in a cooler, vented location where the air can circulate more freely, using a fan (such as a desktop fan or table fan), or just leaving it there.

Your device’s average lifespan will increase and the charger’s internal components will be less stressed if you follow these steps.

Check For Physical Damages In Your Charger

There is a chance that your power adapter has some sort of hardware flaw. There may be suspicious signs of manipulation at the charger’s pin connection to the power connector, such as charring, scorched, and/or bent markings.

These problems usually point to a lack of connectivity or, more likely, an outdated charger. Causing significant damage to your laptop or Macbook and putting you in harm’s way if you’re working in close proximity to electrical outlets, these issues require particular caution.

If your laptop or Mac’s charger keeps getting too hot, the simplest thing to do is to contact a technician. The final piece of advice is to go out and get a brand new replacement charger, preferably from the same shop you bought your laptop or Mac.

Handle With Care

Protect the rubber coating on your adapter cable from being worn away by dragging it across sharp or rough surfaces.

In order to prevent damage to your laptop, you should never plug it into a charger that has exposed cables.

Don’t risk harming your laptop charger by dropping it when travelling with your laptop. Keep your charger from taking repeated hits from the floor.

The charging cable’s copper conductors are easily damaged, so be careful when packing it. Wrapping your power cable in a new way each time will reduce the wear and tear caused by repeated handling.

Keep It, Airy

Make sure your device is charging in an area with enough ventilation. Your charger will overheat if it is left on the bed or covered with a blanket when plugged in. Because of this, you should stay away from confined spaces where your battery charger could overheat.

Put your cursor on the battery icon in the system tray if the charger is on but the battery isn’t charging. Whenever you see the “plugged in but not charging” notice, simply wait a little before trying to use the device again.

If you place some pencils beneath the adapter’s transform box, the airflow around it will improve.

Charge Your Device Regularly

Make sure to charge your laptop frequently, especially when you won’t need it, to keep from having to do so while you’re using it.

Numerous computers now feature long-lasting batteries that may operate without being recharged for 10 hours or more.

Use A Power Strip With Surge Protector

The ability to plug many electronic gadgets into a single wall socket makes power strips a handy tool. The surge protectors on your power strip will shield your electronics from dangerous spikes in voltage.

Check Your Laptop’s Battery

Overheating might be caused by more than just your adapter, so double-check your laptop’s battery as well. Take out the battery and plug in the adapter if your laptop has a detachable battery.

Keep an eye on the adapter’s temperature readings while it’s attached to your gadget. If it stays cold, it’s not the charger but the battery that needs replacing.

Replace Your Adapter

Chargers have an expiration date and are prone to breakdowns just like any other piece of electrical machinery. When your charger becomes too hot, it might provide too much power to your gadget.

If your adapter becomes too hot, it might damage your laptop, therefore it’s best to get a new one.

Switch To Power Saver Mode

Select the option that uses the least amount of power on your laptop to cut down on the frequency of switching modes.

The Power and Sleep option allows you to schedule when your computer will power down automatically. More sophisticated controls may be found in the Advanced section of the power menu.

New in Windows 10, Battery Saver reduces power consumption by throttling back on things like background programme activity and push notifications. Keep away from your charging laptop as much as possible.

Avoid Keeping Your Device On Charger For Long

Make sure that your laptop’s adapter is not constantly connected to your computer, even if you are a heavy user of your laptop. If you want your charger to work as efficiently as possible, give it some time to cool down.

Taking Care Of Your Laptop Charger

A laptop or Mac charger and its components require more than just the adapter and charging device itself to be maintained in good working order; rather, there are a number of other preventative maintenance practises that can go a long way toward ensuring the longevity of the adapter and, by extension, the laptop.

Tip 1: Don’t Overcharge, Or Charge Overnight

Most new laptops include a specific technology that activates when the battery is fully charged to prevent the battery from being damaged by the additional power.

Overcharging (for example, while charging overnight) can cause a lot of undesirable chemical material to build up, which can deteriorate the battery and impair the charger due to overwork. Most laptop batteries nowadays are Li-Ion (Lithium Ion) batteries.

It’s less likely that the charger or battery will be damaged by this kind of damage, although heavy use can nonetheless eventually weaken either component (often through overheating or overuse of the power adapter).

Tip 2: Charger Timings

Of course, it’s simple for the laptop’s battery to deplete rapidly when playing games or running memory/graphics card heavy apps, since the energy required for processing continues to rise.

While it may be tempting to merely plug in the laptop and start working or playing, doing so can actually cause harm to both the laptop and the charging port due to the strain of always giving enough power to keep the laptop operating.

Thus, it is recommended to wait a bit and let the laptop cool down, and then give it a certain amount of time to charge while the laptop is off, or in standby mode without any energy grabbing processes running, in order to prolong the life of your charger and prevent your Mac charger from overheating.

This will allow the charger to slowly charge the battery without any external factors pressuring it to work harder than necessary.

Amount of times this has occurred to you? You’re working away happily on your laptop when all of a sudden it warns you that its battery is about to die. As soon as the lights go out, you’ll have to scramble to find your charger and plug it in.

You would think that plugging in the AC adapter would activate the device, however this doesn’t always happen. There were no indicators that the battery was charging, such as blinking lights or a brighter screen. Is there anything wrong, really?

There are a number of methods for maintaining your battery, however between the electrical socket and your computer, there are a number of potential points of failure. Some issues may be resolved quickly and easily by the user themselves, such as with a software update or a new battery. However, some issues may necessitate a trip to a repair shop or even a complete system replacement.

Identifying the difference between the two can prevent hours of wasted time and costly repairs. Applying an inside-out strategy allows you to zero in on the source of the problem and identify the most cost-effective way to fix it, much faster. In order to fix the problem, follow these steps.

Are You Plugged In?

It may seem obvious, but check to see if your laptop is connected to an electrical outlet. This is one of the most common causes of computers failing to boot.

A laptop that has been turned off cannot be turned on by adjusting its settings or fixing its hardware. Check that the laptop’s power cord is plugged into the wall outlet and that the AC adapter is securely inserted before proceeding.

You should make sure that the AC adapter brick is plugged in and that any detachable wires are properly secured. As a second step, check that the laptop’s battery is firmly inserted into its compartment and that the battery and laptop contact points are in good working order.

Finally, you need to determine if the laptop is the source of the issue.

If you suspect a short or blown fuse, you can test whether or not the problem persists by trying a different electrical outlet with the power cable. It should be connected directly into the wall rather than into a power strip or surge protector.

If it still doesn’t function after this, we know it’s not due to an oversight on the part of the user.

There is an actual problem with the laptop’s power supply; at this point, all that remains is to identify the source of the issue. To do so, we must first remove the areas where it isn’t. We’ll begin with the simplest, most widely-experienced problems.

Lose The Battery

Examine the battery’s condition first. If your laptop’s battery is detachable, remove it and press and hold the power button for 15 seconds to completely discharge the battery. Finally, reconnect the power cord while keeping the battery out of the laptop, and power it on.

Why My Laptop Charger Overheated And Stopped Working?

If the laptop starts up normally when connected to the AC adapter, the battery is likely to be at fault. It never hurts to try again, and you can always try installing the battery in its original location if you think it wasn’t well placed.

If the battery compartment of your laptop is not readily apparent (as is the case with most Macs), you will need to either open the laptop yourself or get it serviced by a professional in order to test the battery.

Make Sure You’re Using The Right USB-C Port

USB-C is quickly becoming the de facto cross-platform standard for linking devices, exchanging information, and recharging batteries.

Thinner gadgets are possible thanks to the new standard, although the shift might lead to some misunderstanding. Some USB-C connectors are data-only and cannot supply power to your device, a decision made by some manufacturers.

Why My Laptop Charger Overheated And Stopped Working?

A few devices include two USB-C connections, one of which is dedicated only to data transfer while the other may also be used to charge the device.

If you’re having trouble charging, check to see that you’re plugged into the right USB-C port. There could even be a charging indication on the side to let you know which port to use.

Is Your Charger Powerful Enough?

Similarly, a power adapter’s compatibility with your laptop’s charging port does not guarantee that it will provide a sufficient charge.

While it’s true that any USB-PD(Opens in a new window) charger should work with a USB-C laptop, many of them simply don’t have enough power to fully charge the device.

If your laptop comes with a 45W charger, you should use a 45W charger or greater to power it.

Although a lower wattage charger may prevent the battery from completely discharging while in use, it will not be able to fully charge the battery.

Why My Laptop Charger Overheated And Stopped Working?

In the unlikely event that it does manage to charge your computer, it will do so at a slower rate than usual. Use only USB-IF-certified USB-C chargers if you must use a non-Original Equipment Manufacturer (OEM) charger (Opens in a new window).

If your laptop can’t be charged through USB-C, then you should probably use the one that came with it.

If you need to charge your laptop and only have access to a cheap, off-brand charger, you may want to reconsider and use the one that came with your laptop instead.


The overheating of your computer’s or Mac’s charger might be caused by a number of factors.

The best course of action is for you to figure out which problem (or problems!) is impacting your laptop charger’s temperature and then try the options that were listed above until the temperature is back to normal.

This is a crucial issue that can save you, your laptop, and your charger from harm caused by malfunctioning adapters, power connectors, and other similar devices.
