Power adapters are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED lamps, communication equipment, audio-visual products, security, computer chassis, digital products and instruments, etc, especially when it comes to laptops. But when we use, in fact, there are many incorrect operations, in order to prevent security risks, causing unnecessary damage and loss. The following Guangzhou seven-up photoelectric co., ltd. will explain the matters needing attention in the safe use of power adapter from the aspect of notebook computer.

1. avoid using an adapter with insufficient voltage and current

At present, the configuration of notebook computers is getting higher and higher, and the power consumption is also rising, especially for P4-M machines with high main frequency. Once the voltage and current of the power adapter are insufficient, it is easy to cause problems such as screen flashing, hard disk failure, battery failure and unexplained crash.

If you are used to take off the battery and plug it in directly, it will be more likely to cause damage (the battery can play a buffering role here). The most terrible thing is that these problems do not appear immediately, but show up after a period of time. When 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 heating ratio of the machine is usually large, which is unfavorable to the life of the notebook computer.

Do not drop or flood the 2..

For portability, the internal structure of the power adapter of the notebook computer is very compact. Although it is not as fragile as the battery, it should also avoid impact and fall. The author once used the power adapter that fell, causing a trip at home. Later, it was found that the internal circuit was short-circuited during maintenance.

As for flooding, because most of the power supply is placed on the ground, it is often discovered after flooding, so you should form a good habit of using it. First connect the power supply terminal and then plug the plug into the notebook computer, and try not to put the power supply directly on the ground, but put it where you can see it.

3. avoid poor heat dissipation

Many people attach great importance to the heat dissipation of notebook computers, but few people care about the power adapter. In fact, the heat of the power adapter of many machines is by no means inferior to that of a notebook. Be careful not to cover it with clothes and newspapers, and place it in a well-ventilated place. In this regard, Xiaobian has personal experience, that is, a notebook used in his early years, because the power adapter itself has high heat and is convenient to use on the bed. As a result, the surface is partially melted because the heat cannot be discharged.

A suitable power adapter requires safety certification, and a power adapter with safety certification can protect personal safety. Play to prevent electric shock, fire and other dangers.
