3- Placing The Laptop Charger On The Surface Trapping Heat
When you notice that the charger or laptop is placed in any area restricting airflow, it can cause overheating. For example, the sofa, bed, or other surfaces will trap heat while increasing the overall temperature.
Fact:
When you are placing charger in the covered area, you are blocking hot air not to get outside which will increase the temperature of the charger.
4- Problem With The Laptop
A problem with the laptop itself may cause a hot laptop power adapter. If the laptop is overheating, it may also cause the adapter to overheat. Check the laptop for any signs of overheating, such as a hot case or problems with the fan. If the laptop appears to be overheating, try using a different power adapter or contact the manufacturer for assistance.

How To Deal With A Hot (Overheating) Power Adapter?
Laptop power adapters can get hot, mainly if used for extended periods or not properly ventilated. If you are having trouble with your adapter getting too hot, there are a few things that you can do to help mitigate the problem.
1- Keep the Adapter Airy
First and foremost, it is important to ensure that the adapter has good airflow. If it is constantly being covered by a blanket or other piece of clothing, the heat will have nowhere to go and will build up inside the adapter.
Additionally, if you use the adapter on a soft surface like a bed or couch, the heat will have a harder time dissipating and will again build up inside the adapter. Try to use the adapter on a hard, flat surface whenever possible to give it the best chance to stay cool.
Fact:
Always use laptop and its charger in a open area instead of covering.
2- Unplug When Not in Use
Another easy way to help keep your adapter from getting too hot is to unplug it when you are not using it. Even if your laptop is turned off, the adapter will still generate heat as it is constantly powered. Unplugging the adapter when you are not using your laptop can help ensure it stays cool.
3- Use A Power Strip
If your adapter is still getting too hot, even when taking the above precautions, you may want to use a power strip. Power strips often have built-in features that help to regulate the flow of electricity and prevent overheating. This can help to keep your adapter from getting too hot, even if you are using it for extended periods.
4- Check the Laptop’s Battery
It is also important to ensure that your laptop battery is in good condition. A damaged or degraded battery can cause the adapter to work harder and generate more heat. If your laptop’s battery is not in good condition, it is best to replace it to help keep your adapter from getting too hot.
Fact:
With the age of batteries, the cells in it get weak as well. So it cannot pass full current to the laptop which can damage your laptop.
5- Switch the Adapter to Power Saving Mode
If your laptop has a power-saving mode, you may consider using it. Power saving mode can help to reduce the amount of power your adapter uses, which can, in turn, help to keep it from getting too hot. Consult your laptop’s manual to see if it has a power-saving mode and how to enable it.
6- Keep the device off charge for a short period.
If you are not using your laptop but plugged in and charging, the adapter will still generate heat. To help keep your adapter from getting too hot, it is best to unplug it when you are not using your laptop.
7- Replace the Adapter If It’s get Damaged
If you notice that your power adapter is damaged, frayed, or otherwise not in good condition, its time to replace it. A damaged power adapter can cause your laptop to overheat, leading to many problems.
Troubleshooting of a hot laptop power adapter:
If your laptop power adapter is running hot, there are a few things you can do to troubleshoot the issue.
- First, check to ensure the adapter is properly plugged into the laptop and a power outlet. If the adapter is not plugged in correctly, it will not work properly and can overheat.
- Next, check the power cord for any damage. If the cord is frayed or damaged, it must be replaced.
- If the adapter and cord are both in good condition, the issue may be with the laptop itself. Ensure the power settings are set to run the laptop at full power.
- If the laptop runs on battery power, it may be using more power than the adapter can provide, causing it to overheat.
If you still have trouble with a hot laptop power adapter, contact the manufacturer for further assistance.
