Laptop adapter maintenance

After using the notebook for a long time, the hottest place is not the surface of the fuselage, or even the air outlet. It is the power adapter next to the notebook. It often feels hot when picked up. It is really worrying.

Since the power adapter is a switching power supply that operates under high voltage and high current conditions, the working load is relatively heavy, and it is a fully enclosed structure. There is no heat dissipation hole on the outer casing, and there is no fan inside to assist heat dissipation. Therefore, the power adapter is working. The internal temperature is very high. Especially in the hot summer, you can feel the hot hand by touching the surface with your hands, and the internal temperature is higher. Therefore, in daily office and entertainment, it should be properly maintained and maintained.

1.Create a good cooling environment.

When using the notebook in a high temperature environment, place the power adapter in a place that is not exposed to direct sunlight and ventilation; do not place the power adapter near the heat dissipation air outlet of the notebook, otherwise the heat of the power adapter will not be dissipated. To absorb some of the heat.

On a hot summer day, we can put the adapter on the side to increase the contact area of the adapter with the air, so that the heat of the adapter is better. For 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, stop using it in time.

When the power adapter emits large working noise or even smoke, it is often damaged or faulty. It should be stopped immediately and can be used again after being repaired by professional engineers.

3.Use caution when using non-original power supplies.

Non-original power adapters may have some differences in output interface, voltage and current values . If not properly matched, it may affect the stability of the notebook operation, or even more serious consequences.…
