- Is the notebook power adapter hot? Actually, this is normal. It has to work. To convert the output power, it will consume energy. Some of it will become heat. Also, see if you have a battery installed, or if the battery is Normal and so on.
Is the notebook power adapter hot? Actually, this is normal. It has to work. To convert the output power, it will consume energy. Some of it will become heat. Also, see if you have a battery installed, or if the battery is Normal and so on. The notebook power adapter is actually a high-precision, high-efficiency switch-type regulated power supply. Its function is to convert 220V AC mains into low-voltage DC, which provides stable power for the normal operation of the notebook. It is even called a laptop. The "source of power".
As long as the temperature of the power adapter is within the design range, that is, the power adapter temperature is within the normal range, it is generally not dangerous!
Why is the power supply hot? The conversion efficiency of the switching power supply can only reach 75%-85%, which may be the main reason. Switching power conversion efficiency is still difficult to find a better conversion method.
When the switching power supply performs voltage conversion, part of the energy is lost. Except for a small part of the loss in the form of waves, most of it is emitted in a thermal manner.
When using a laptop, try to place the power adapter in a place with good ventilation and heat dissipation. Never put anything like a book on the power supply. Create a good cooling environment for the power adapter. As for the hot feeling, don't worry, the power adapter does not heat up, but it is not normal, especially in the summer!
