What happens when the laptop power supply gets hot?

Why is the laptop power supply so hot?

The inside of the power adapter is composed of a large inductor, which is the only way for current transmission. The box is closed. If the heat does not exceed the tolerance of your hand, it is normal. Because it has to work and convert output electricity, it will consume energy, and part of it will turn into heat energy. Don't worry, there is no danger and it won't explode.

Is it normal to have heat?

The inside of the laptop power adapter is a switching power supply that works under high voltage and high current conditions, and the workload is relatively heavy. , and it has a fully enclosed structure. There are no heat dissipation holes on the casing, and there is no fan inside to assist heat dissipation. Therefore, the internal temperature of the notebook power adapter is very high when working. Especially in the hot summer, the surface can feel hot when you touch it with your hands, and the internal temperature is even higher.

The power adapter heats up due to the combination of battery charging and computer consumption. It can be set in notebooks with battery management software. Create a good cooling environment and place the power adapter in a ventilated location that is not exposed to sunlight. Remember not to use it at high temperatures for too long. If you have to use it for a long time, you must pay attention to heat dissipation. You can put the fan aside to assist with heat dissipation.

In a high temperature environment, placing the adapter on its side to reduce the contact with the ground area can allow the adapter to better dissipate heat and achieve a heat dissipation effect. You can insert a narrow plastic or metal block between the adapter and the desktop to speed up the heat dissipation of the adapter.

Is it normal for the laptop power adapter to heat up? In fact, as can be seen from the above content, heat generation is a normal phenomenon. Just like a mobile phone charger, it is normal for it to heat up during charging. As long as it is used normally, there is no need to worry too much.
