  Laptops are very common in our lives. We all know that the battery life of laptops after charging is very short. Generally, the battery can only last about two hours, so they are plugged in during use. However, after long-term use, the power adapter will easily heat up. Is this abnormal?

  The inside of the power adapter is composed of a large inductance, which is the only way for current transmission. The box is closed. It is normal if your heat does not exceed your hand's ability to accept it. Because it has to work and convert the output electricity, it will consume energy and part of it will become heat energy. Don't worry, there is no danger, and it will not explode. The length of time does not matter, it will become very hot after one or two hours of use, but it will always maintain this temperature. And the outer shell of the notebook's power adapter is high temperature resistant and will not burn out.

What does a hot laptop power adapter indicate?(图1)

  Because the inside of the notebook power adapter is a switching power supply that works under high voltage and high current conditions, the workload is relatively heavy, and it is a fully enclosed structure. There is no heat dissipation hole on the shell and no internal fan to assist heat dissipation. Therefore, the notebook power adapter The internal temperature is very high during work. Especially in the hot summer, you can feel hot when touching the surface with your hands, and the internal temperature is higher. How do we need to maintain it?

  1. Create a good heat dissipation environment, and place the power adapter in a location that is not exposed to sunlight and is ventilated. Remember not to use it for too long under high temperature. If you must use it for a long time, you must pay attention to heat dissipation. You can put the fan aside to assist in heat dissipation.

  2. The heat of the power adapter is generally caused by battery charging and computer consumption. It can be set in a notebook with battery management software.

  3. In a high temperature environment, put the adapter on its side to reduce the contact with the ground area, so that the adapter can better dissipate heat and have a heat dissipation effect. A narrow plastic block or metal block can be inserted between the adapter and the desktop, which can accelerate the heat dissipation of the adapter.
