When the laptop is charged and unplug the power adapter, you will find that the power adapter is hot and the temperature is too high. Is it normal for the laptop power adapter to be very hot during the charging process? How to solve this problem? This article is for everyone Solve doubts.

It is normal for the notebook power adapter to become hot when in use. It is always running. To convert the output electricity, it will lose kinetic energy, and part of it will become heat. At the same time, it is necessary to see whether the battery is installed. Or is the battery normal? The notebook power adapter is actually a high-precision, high-efficiency switch-type regulated power supply. Its function is to convert 220v AC mains power into low-voltage DC power to provide stable power for the normal operation of the notebook computer. It is even called a notebook The "power source" of the computer.

The conversion efficiency of the power adapter to the power supply can only reach about 75-85 at this stage. During the voltage conversion, part of the kinetic energy is lost. Except for a small part of the loss in the form of waves, most of it is in the form of heat. Exudes. The greater the power of the power adapter, the greater the loss of kinetic energy, and the greater the amount of heat generated by the power supply.

At this stage, the power adapters on the market are all sealed and packaged with fire-resistant and high-temperature resistant plastics, and the heat generated inside is mainly dissipated through the conduction of the plastic shell. Therefore, the surface temperature of the power adapter is still quite high, and the maximum temperature may even reach about 70 degrees.

As long as the temperature of the power adapter is within the design solution area, in other words the temperature of the power adapter is within the normal area, there is usually no danger!

In summer, you should pay more attention to the heat dissipation of the laptop itself! The most important thing is to ensure the room temperature. If the room temperature is too high, no matter how high the temperature is, it is useless! When using the laptop, it is best to turn on the air conditioner! At the same time, you should try to keep the bottom of the laptop empty. Or use the same thickness and small size to padded the bottom of the notebook! Try not to use a keyboard protective film, because the keyboard is also a key part of the notebook’s heat dissipation! The rest of the heat dissipation components (the laptop heat dissipation components of each corporate brand may be different ) Also should not be covered by objects!
In addition, you also need to clean up the dust on the cooling fan port regularly! In the hot summer, the notebook needs your double care!
