Online explanation! What should I do if the laptop power adapter is hot? Is it normal?

1. Technology is advancing by leaps and bounds, people's living conditions are getting better and better, and everyone is basically a family. The progress of network technology facilitates us to search for information and materials, Taobao, watching news, etc., and has become indispensable for work, life, leisure, entertainment, etc. The main frequency of notebook computers is changing with each passing day, the LCD screen is getting bigger and bigger, and the power of the notebook power adapter is also increasing, reaching about 100W, which is almost a small desktop Power Supply! If you touch it with your hands, you might be surprised if you are timid, but you are just a hot potato! It won't catch fire or something? This is the worry of many people!

2. What should I do if the laptop power adapter overheats?

It is normal if the heating temperature is constant. The notebook power adapter is actually equivalent to the power box of the desktop computer. The desktop computer has an electric fan, so it is not very hot, but the wind blown out after using it for a long time is still hot. The notebook is completely dissipated by the shell, so the heat is normal. And it will be hotter in summer, as long as the power supply can be normal, as long as the hand can touch it. It can also be placed on the radiator to assist heat dissipation. Today's laptops generally have overheating protection, and overheating will automatically power off protection.

3. Overheating protection circuit of power adapter

The overheating protection types of the power adapter can be divided into the following categories: automatic reset type, manual reset type, non-renewable, non-resetable type and various other types that can provide equivalent thermal protection.

4. Five methods to solve the power adapter heating
(1) Create a good heat dissipation environment, and place the power adapter in a location that is not exposed to sunlight and ventilated. Remember not to use it for too long at high temperatures. If you must use it for a long time, you must pay attention to heat dissipation. You can put the fan aside to assist heat dissipation.
(2) In a high temperature environment, place the adapter on its side to reduce the contact with the ground area, so that the adapter can better dissipate heat and achieve the effect of heat dissipation.
(3) A narrower plastic block or metal block can be placed between the adapter and the desktop, which can speed up the heat dissipation of the adapter.

(4) The heat of the power adapter is generally caused by the combination of battery charging and computer consumption. We can set it in the notebooks with battery management software.
