With the development of global diversification, our lives are constantly changing, including all kinds of electronic products we come into contact with, so you must not know some components of these products, such as power adapters.
However, when you use it, there are actually many incorrect operations. In order to prevent potential safety hazards and cause unnecessary damage and loss, the following will explain the precautions of the safety adapter.
1. Do not use adapters with insufficient voltage and current
This is similar to the first taboo on the use of battery packs, but here is from the perspective of the whole machine. Nowadays, the configuration of notebook computers is getting higher and higher, and the power consumption is also rising. Especially the high-frequency P4-M machine consumes a lot of power. Once the voltage and current of the power adapter are insufficient, it is easy to cause the screen to flicker and the hard disk to have bad sectors. Problems such as battery not fully charged and unexplained freezes.
Battery powered, the output of the battery is pure DC, which is very clean. The voltage of the battery is neither possible nor required to be designed to be very high. The chemical characteristics of the lithium battery determine that the output voltage of a cell can only be around 3.6V, so Many batteries use three-stage series connection, and 10.8V has become a very popular battery voltage. The nominal value of some batteries is slightly larger than the integer multiple of 3.6V, such as 3.7V or 11.2V, etc., in fact, to protect the battery.
If you are used to removing the battery and plugging it directly into the power supply, it is more likely to cause damage (the battery acts as a buffer here). The most terrible thing is that these problems do not appear immediately, but only after a period of time. By the time the problems occur, they are often lost. In addition, when the current and voltage of the power adapter are insufficient, it may cause the line load to increase, and the heat of the machine is inversely larger than usual, which is not good for the life of the notebook computer.
Power supply, the situation is a little more complicated. First of all, it is necessary to further stabilize and filter the added voltage to ensure stable operation in the case of poor power supply performance. , the other way to charge the battery, the part that supplies power to the notebook is the same as when the battery is powered.
2. Do not fall or flood
For the sake of portability, the internal structure of the power adapter of the laptop is very compact. Although it is not as fragile as the battery, it should also be avoided from impact and fall. Internally shorted. As for flooding, because most of the power supply is placed on the ground, it is often discovered after it is flooded, so you should develop a good use habit, connect the power supply first and then plug the laptop into the laptop, and try not to put the power supply directly on the ground , and place it where you can see it.
The part that charges the battery needs to be added to the battery cell through the battery’s charging control circuit. The control circuit can be very complicated, so the power supply voltage must be greater than the battery cell voltage to have sufficient capacity to supply each unit of the charging control circuit.
3. Avoid poor heat dissipation
Many people attach great importance to the heat dissipation of the laptop itself, but few people care about the power adapter. In fact, the power adapters of many machines are not inferior to notebooks, so be careful not to cover them with clothes and newspapers, and place them in a well-ventilated place. In this regard, the editor has personal experience, it is a notebook used in the early years, because the power adapter itself has high heat, and it is convenient to use on the bed, as a result, the surface is partially melted because the heat cannot be discharged.
In the process of research and design, there are bound to be problems of one kind or another, which requires our scientific researchers to constantly sum up experience in the design process, so as to promote the continuous innovation of products.
