Laptop charger/laptop power adapter maintenance knowledge: Laptops are no longer unfamiliar to us today, because the biggest advantage of laptops is that they are small and easy to carry, so they are the best choice for people who work outside. , then I believe many users have the same feeling when using a notebook: after using a notebook for a long time, the hottest place is not the surface of the fuselage, or even near the air outlet, but the power adapter next to the notebook, which often feels hot when picked up. It feels like it is really worrying. Will it suddenly stop working one day, or have malfunctions such as howling or smoking? The following is a detailed introduction to the maintenance knowledge of laptop chargers/laptop power adapters.

The notebook adapter is actually a high-precision, high-efficiency switching-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. It is even used It’s called the power source of your notebook.

Because the 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 are no heat dissipation holes on the casing, and there is no fan inside to assist heat dissipation. , so the internal temperature of the 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. Therefore, it must be properly cared for and maintained during daily work and entertainment.

Laptop charger/laptop power adapter maintenance knowledge:

1. Create a good cooling environment. When using a notebook in a high-temperature environment, the power adapter should be placed in a ventilated place that is not exposed to direct sunlight; do not place the power adapter near the heat dissipation outlet of the notebook, otherwise not only the heat of the power adapter will not be dissipated, but also To absorb some heat.

In hot summer, we can place the adapter on its side to increase the contact area between the adapter and the air, so that the heat of the adapter can be better dissipated. In order to obtain better heat dissipation, we can also insert a narrow plastic block or metal block between the adapter and the desktop to increase the air convection speed around the adapter and speed up the heat dissipation of the adapter.

2. If an abnormality occurs, use should be stopped immediately. When the power adapter makes loud noise or even smoke, it is often damaged or malfunctioning. It should be stopped immediately and must be inspected by a professional engineer before it can be put back into use again.

The above is a detailed introduction on how to maintain the laptop power adapter.
