The laptop is now no longer a state-of-the-art technology product, and most people are able to buy it. However, when buying, we must pay attention to quality. When buying a laptop, you only need to look for a brand to purchase. Basically, there will be no quality problems. The key lies in the quality of the computer's subsidiary items. This is the most important issue that you should pay attention to.

    As long as the laptop is branded, there will be no problem, but its power supply must be paid attention when it is purchased. The reason is very simple, because there is no power supply, then no matter how good the laptop can not bring you convenience, to know the laptop's battery usage time is very short, up to two hours will be just full of battery consumption clean, Therefore, most people use laptops with their power plugged in. At this time we should pay special attention to the laptop power adapter (also known as the laptop charger), and the most important place for the notebook's power supply is the power adapter, so we should be extra when buying a laptop The concern is the quality of the power adapter.

    The main function of the power adapter is to convert the 220V mains to the low voltage DC required by the notebook, which is used to regulate the voltage of the laptop, and regulate the voltage entering the notebook so that it can work on a safe basis. Some companies directly use a power adapter to sell laptops. They say that they are dedicated, but they are not. They haven't even considered whether the current used by the power adapter is suitable for the operating current of the laptop. Therefore, when purchasing a laptop, we should first understand the current and voltage of the laptop, and then observe the current and voltage of the power adapter. If the two are different, we must ask the salesperson to you as soon as possible. Change, because if you use such a power adapter to run a laptop, it can easily affect the life of the computer.

      There is the problem of quality, in the purchase of a suitable laptop, but also to ask where the manufacturer of the power adapter is, if it is produced by Shenzhen Jinbaotong Technology Co., Ltd., then there is no problem in terms of quality, if it is some never If you listen to a small manufacturer, then you must be careful. The average sales person will tell you that the original factory is allotted, then this time we have to ask how long it takes to use the prescription, it must be purchased and used for a longer period of time, so that when using a laptop computer will be more secure.

     For many people, using a notebook has become a very common thing, especially since many students must bring their own notebooks after attending university. The development of notebooks has also seen a lot of new situations, especially the emergence of such products as Superbooks, which has greatly improved the notebook's endurance. However, regardless of the extent to which the notebook's battery life is improved, it is inextricably linked to the power adapter. There are a lot of problems when using laptops and power adapters. Today we will find some of them to answer.

     Many people have questions about using a power adapter. That is, our laptop is the same, and the power adapter is the same. Why is the power of other people's power is relatively low, and my power is very hot? In fact, this phenomenon is very common, and the temperature of the notebook power adapter is not actually determined by itself, but is determined by the use of notebooks. Therefore, when our power supply is relatively hot, do not always suspect that your power supply is broken. This is a very irrational idea, because the power adapter is generally very bad. The key is to look at the use of your laptop, if you open too many applications, it will naturally increase the temperature of the adapter.

     When people use laptops, there is often a problem that many people will find when using a notebook, the standard voltage of their notebook and the voltage provided by the power adapter are often different, so many people will doubt this Whether the setting will cause a problem with the notebook. In fact, this kind of thinking is still worrying. Because the standard voltage of the notebook is often the voltage marked with our battery, and this is different from the voltage provided by the adapter. Because the voltage provided by the battery is a very efficient DC, it is not necessary to design the voltage very high, and it is not necessary. The form of power supply is very complicated, and the voltage needs to be set higher.
