Is your computer charger heating up? 

What do you do when it gets so hot that you can’t touch it? A hot charger or laptop adapter is a bad sign, and not doing anything about it can lead to more devastating consequences. If you don’t want to deal with an overheated charger, you should make sure your laptop adapter is in a properly ventilated room, avoid using your laptop while charging, and handle your charger with care to avoid breaks, bends, or wears on the charger cord.

In this article, you will learn which activities can cause your charger to overheat and how to prevent your charger from overheating.


Is it a good thing if your laptop charger gets hot?

Your laptop adapter will feel relatively warm while in use; especially in situations where you are using your laptop and also charging it. This is the normal temperature for a laptop adapter. It is when the adapter gets so hot that you can hardly touch it that you might have a problem. This can happen if you use your computer while it is charging.


The computer adapter is covered with plastic, this means that there is no place for the heat it generates to escape to. If the workload on your computer is high, you should expect the adapter to get seriously hot. If it is a relatively low workload, the adapter’s temperature will still increase to a significant level. The best way to prevent overheating is to not use your laptop for tasks that involve high-level processing while it is charging. Your computer charger can get overheated for a lot of reasons, some of which will be discussed below.


What are the things that cause overheating? 

There are a lot of things that can make your computer charger overheat. Some of them are things we do every day while using our computers.

  • Charging your laptop in an unventilated room.

As said earlier, merely charging your laptop while also using it increases the temperature of the charger. If you are using the charger in a room where there’s little ventilation or you place it on a surface that traps heat, this will increase the temperature and cause overheating. Using the laptop in an unventilated room can also cause the battery to overheat, when that happens, the computer might shut down on its own.

  • Buying cheap and untested chargers for your laptop.

There are a lot of fake laptop adapters in the market, these adapters are very cheap but also unreliable. Using them will compromise your laptop battery and may even lead to some electrical faults in your device.

  • Non-compatible device

There are situations where your laptop adapter and your laptop battery are not compatible with each other. For instance, if you use a gaming laptop, you would need an adapter that is able to draw and ‘adapt’ high electrical voltages. If you get an adapter that is unable to handle that amount of power, the adapter will get too hot while trying to conduct the amount of voltage needed.

  • Faulty power socket

A short-circuit electrical outlet can also make your laptop adapter to overheat.

How to stop my charger from overheating?

The first thing to do if your charger is overheating is to shutdown your computer and unplug the adapter from the socket. Wait until the adapter has cooled down to continue charging, if it gets hot again, try the following solutions.

  • Keep it ventilated

Always keep your laptop in a well ventilated room. Putting your adapter on surfaces that trap heat will make it overheat and might cause more damage to your battery. So it is essential to avoid places like beds, cushions, or blankets, instead place them on flat and hard surfaces. You can also improve ventilation to the adapter by placing a couple pencils under it so that the air can cool all its sides.

  • Don’t handle roughly

Your laptop adapter is made with plastic, this means it can easily get broken if handled roughly. You should also make sure to prevent the cords from fraying, breaking, or tearing. Inspect the wires to check for curious bents or frayed areas. Additionally, when packing your charger, don’t pack it too tightly as it can lead to broken inner wires.

  • Use a surge protector

A short circuited socket can cause your adapter to overheat, if you want to avoid this, plug your laptop charger to a surge protector before connecting it to the socket. This will protect it from high electric currents.

  • Always check and charge your laptop battery

Some laptop batteries can work for up to 10 hours, charging your laptop battery fully will ensure that you don’t have to use your computer while charging. This will prevent overheating as a result of high workload and reduce the need for constant charging which will ultimately protect your battery life.

Sometimes the problem might be with your battery. If your laptop has a removable battery, remove the battery and connect the adapter to your computer. If the adapter temperature turns cool after this, that means you need to change your battery.

  • Change to power saver mode

Your computer power saver mode will help you conserve battery power and prevent constant charging. The power and sleep menu also allows you to instruct the computer to sleep if it is not in use or shutdown at a specific time.

Engage power saver mode, search “power plan” in your computer search box, open the result and set your plan to the balanced option. Then, go to Windows bottom right corner and double-click on the battery icon. Navigate to power saver mode and activate it.




If any of the above steps don’t work, then you should consider taking your computer to a repair specialist. Getting a new charger can also solve the constant overheating problem. Remember to get one that is compatible with your computer, an incompatible adapter will likely overheat and can potentially damage your computer battery.
