Due to the fact that the power adapter is a switching power supply that operates under high voltage and high current conditions, with a relatively heavy workload and a fully enclosed structure, there are no heat dissipation holes on the shell, and there is no fan inside to assist in heat dissipation. Therefore, the internal temperature of the power adapter is very high during operation. Especially in hot summer, touching the surface with your hand can feel hot, while the internal temperature is even higher. Therefore, in daily work and entertainment, it is necessary to carry out appropriate maintenance and upkeep. So how should the laptop power adapter be maintained?

Laptop power supply

1. If any abnormalities occur, stop using it in a timely manner. When the power adapter emits significant working noise or even smoke, it is often damaged or malfunctioning. It should be stopped immediately and put into use again after being repaired by a professional engineer.

2. Be cautious when using non original power supplies. Non original power adapters may have some differences in output interface, voltage, and current values (or if the nominal and actual values do not match). If not matched properly, it may affect the stability of laptop operation, and even more serious consequences.

3. Create a good heat dissipation environment. When using a laptop in a high temperature environment, the power adapter should be placed in a well ventilated area away from direct sunlight; Do not place the power adapter near the heat dissipation outlet of the laptop, otherwise not only will the heat from the power adapter not dissipate, but it will also absorb some of the heat. In hot summer, we can lay the adapter on its side to increase its contact area with the air, thereby allowing the adapter's heat to be better dissipated. To achieve better heat dissipation, we can also insert narrow plastic or metal blocks between the adapter and the desktop to increase the air convection speed around the adapter and accelerate the heat dissipation of the adapter.
