Laptop Adapter Pcb Manufacturer

How to buy a laptop adapter? 

I believe that many people have the same feeling: after a long time to use the laptop, the laptop next to the power adapter, pick up often have a hot feeling, it is really alarming, worried that it will not be because of the perennial high temperature appears suddenly strike, or whistling, smoking and other failures.

Due to the notebook power adapter is a work in the high voltage, high current state of the switching power supply, the workload is relatively heavy, and is a fully enclosed structure, there is no cooling holes in the shell, no internal fan to assist in heat dissipation, and thus the power adapter in the work of the internal temperature is very high. Especially in the hot summer, with a hand touching the surface can feel hot, the internal temperature is even higher. Therefore, in the daily office, entertainment, it is necessary to carry out appropriate care and maintenance.

1. Create a good heat dissipation environment. When using your notebook in a high temperature environment, place the power adapter in a ventilated place that is not exposed to direct sunlight; in the 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 from the adapter can be better dissipated. In order to get a better heat dissipation effect, we can also put a narrower plastic or metal block between the adapter and the desktop to increase the air convection speed around the adapter and accelerate the heat dissipation of the adapter.

2. Abnormalities should be stopped in time. In the power adapter issued a large work noise or even smoke, often has been damaged or failure, should immediately stop using, by a professional engineer after overhauling before being put into use again.

3. Use non-original power supply to be cautious. Non-original power adapter in the output interface, voltage and current value, etc. There may be some differences (or nominal and actual inconsistency), if not properly matched, may affect the stability of the operation of the notebook, or even more serious consequences.

We use laptops in our daily lives, pay attention to the maintenance of the power adapter, but also pay attention to not fake and shoddy non-standard power supply. Otherwise, no matter how you maintain it, charging abnormalities may occur.
