How to maintain the notebook power adapter
time2006/10/31
- Power adapters for different brands of notebooks have some differences in output interfaces, voltage and current values, and therefore cannot be mixed.
The notebook power adapter is actually a high-precision, high-efficiency switch-type regulated power supply. Its function is to convert 220V AC mains into low-voltage DC to provide stable power for the normal operation of the notebook.
Because the power adapters are designed in a fully enclosed structure, there are no vents on the housing, and there is no fan inside to assist in heat dissipation. Therefore, the internal temperature of the power adapter is high during operation. 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.
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, not only the heat of the power adapter will not be dissipated, but instead Also 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. An abnormality should be stopped 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.
Reasonable charging
When the battery of the notebook is in the charging state, do not run large 3D games and other programs that make the whole work load heavier, so that the battery charging speed becomes slow or unfilled due to insufficient power supply output power shortage, and the power adapter load Excessive weight, etc.
Power adapters for different brands of notebooks have some differences in output interfaces, voltage and current values, and therefore cannot be mixed. Otherwise, it will cause the battery to be fully charged, the screen to flash, etc., and the motherboard or other hardware will be burned out. Power adapters for notebooks of the same brand and different models should be used with caution when switching. It is recommended to consult the notebook manufacturer before operating.
