Parallel imports, products that should be sold in other countries or regions, are sold in the domestic market through improper channels to avoid tariffs. According to the truth, such products come from the same production line of the manufacturer, and the quality is indistinguishable. However, due to the improper supply of goods, it is hard to say that there will be no tricks, especially individual profiteers who shoddy goods, causing quality problems and greatly infringing on the rights and interests of consumers. As a "special" product in the notebook market in China, parallel notebook computer products are really gratifying and worrying. Selling parallel laptops as licensed products (mainly concentrated in high-end models of some brands) is also the biggest loss to consumers in all notebook sales fraud. How to distinguish between licensed goods and parallel goods simply and quickly has become a compulsory course for all buyers.

1. Check the packaging and body logo of the notebook computer to identify the licensed parallel goods. Generally, the outer packaging of licensed notebook computers is marked with some basic information of notebooks in simplified Chinese characters, while parallel imports have no outer packaging, or the fonts on the outer packaging are traditional Chinese, English and other fonts. More identification marks can be found on the body of licensed notebook computers, first of all, the 3C certification mark of China. Computer basic knowledge test questions and answers Secondly, you can also identify whether the notebook is a regular licensed product by querying the serial number of the notebook computer. At present, most notebook manufacturers provide online inquiry service of fuselage serial number. Users only need to log in to the established page and enter the serial number on the back of the fuselage, and then they can query various detailed information of this model, including the factory configuration, serial numbers of various hardware parts, warranty start date, sales area, etc. Thirdly, we can quickly identify the machine by its special model code. In order to distinguish the same model sold in different countries and regions, many manufacturers will mark an additional number on this model. For example, some brands will mark a C in the serial number of notebook products sold in Chinese mainland (this method is for reference only, after all, not all models use this special number).

2. Pre-installed laptop system, random programs and data, to distinguish between licensed and parallel imports. Because it comes from abnormal channels, most parallel laptops need to reinstall the operating system, and parallel importers are obviously installing valuable genuine systems for users. Moreover, the licensed random user manual is in simplified Chinese with relevant warranty documents, which is exquisite in workmanship. Parallel imports, whether random software CDs or user manuals, are mostly in traditional Chinese or English.

3. Keyboard identification method for distinguishing licensed parallel imports from notebook computers The keyboards of licensed notebook computers are all standard Gong keyboards. For parallel imports, keyboards with special marks such as Japanese and traditional Chinese may appear due to different original sales places.

4. Notebook computer manufacturers' free hotline identification, distinguishing between licensed products and parallel products. At present, most notebook manufacturers have established a 800 (or 400) free hotline service system for each calendar. Users can also quickly identify whether their laptops are licensed by calling the hotline of the brand manufacturers they buy. Although we don't resist parallel imports, we are concerned about the behavior of some unscrupulous merchants selling parallel imports as commodities. Hate it. At present, the parallel imports in the domestic market are mainly Thinkpad, and there are also some mixes of HP and some Japanese brands. Consumers may wish to identify according to the method in this paper when purchasing. Be careful when buying invoices. As the last step of purchase, many consumers will ignore the importance of invoices after receiving the goods. In fact, the invoice is one of the legal documents for merchants to fulfill the national three guarantees. Once disputes arise in the future, consumers without invoices will sometimes face a very bad situation. No invoice sometimes means no warranty. When some international brand notebooks are guaranteed, users need to provide sales invoices, such as Lenovo Thinkpad series, Toshiba, Sony, etc., and even write the serial number of the purchase model on the invoice to enjoy the whole after-sales service. If there is no invoice, the machine will not be able to enjoy the service of 7-day return and 15-day replacement if there is a problem within the specified period of three guarantees. There are also some international brands, such as Acer, Asus, etc., which can enjoy the warranty in their region without an invoice, but such warranty is likely to be a general warranty. If the screen, processor and other core components are broken, it is difficult to enjoy the warranty without an invoice. If in other places, these products will not be able to get regular after-sales service.

In addition, most brand notebooks need to show the warranty card and tender at the same time when they are sent for repair, otherwise unnecessary problems will occur. In addition, if the user accidentally loses his laptop, he can ask the brand maintenance station to temporarily detain the laptop when receiving the purchase invoice and related warranty documents. Asking for the purchase invoice is only basic, and the shooting down of the invoice is also related to whether the notebook can enjoy the warranty service smoothly in the future. In some brand after-sales maintenance centers, users often encounter unnecessary twists and turns because their invoices are not standardized. Therefore, consumers should also pay attention when filling in the invoice. All items on the invoice must be filled in in a standardized way, and the model and product code of the purchased notebook also need to be filled in one by one, which is generally stipulated in the manufacturer's warranty terms. The warranty card must be stamped with the official seal of the merchant, and the attachment should be sent to the manufacturer by the merchant. In this way, the parties can be called a perfect proof of purchase. There is also a situation worthy of attention: some businesses even offer * * * discounts to customers in order to get more profits, which undoubtedly causes great damage to consumers' rights and interests. To avoid such problems, we must first look at the scale of this company, which is often done by small companies. Secondly, it depends on whether the business license and the company seal on the invoice are consistent. Thirdly, it is best to let the financial department issue the invoice face to face and look at the tax number on the invoice.

I can understand the tactics of business advertising, the most commonly used means in notebook advertising. In some merchants' posters, I even saw the slogan "Fast Gigabit network card, which is 10 times faster than ordinary network card", which made people somewhat puzzling. Overwhelming advertisements often confuse consumers. Many brands claim that their products are excellent in performance and quality. How to choose? If consumers are not careful, they will fall into the "trap" of business leaflets. In the face of these ambiguous and even exaggerated advertisements, how can we distinguish them?

1. Notebooks should be divided into three or six processors to distinguish parallel dual-cores, which is an important indicator to judge the performance of a notebook. Consumers can see the slogan "Intel dual-core notebook 4××××××" in the store. Many unsuspecting consumers think that dual-core notebook is high performance now, and it is worthwhile to buy a dual-core notebook for more than 4,000 yuan! Who knows that dual-core processors should be divided into three, six, nine and so on. According to different manufacturing processes and configurations, Intel's dual-core processors are called Core and Core 2. Core processor, that is, the first generation of mobile dual-core, takes T2*** as the model, and the secondary cache is as high as 2MB, while Core 2 is T5*** and T7***, using 2MB and 4MB of secondary cache respectively. There is a difference in price and performance.

2. Notebooks distinguish the memory of licensed parallel imports. Whether it is independent or * * *, it is often seen that merchants play with a notebook computer with an independent memory of more than 256M m. In fact, this statement remains to be verified. Both NVIDIA's TurboCache and ATI's HyperMemory can make display chips use system memory as video memory. For example, the MobilityRadeonX 1300 graphics card used by ThinkpadT602007-BT 1 only uses the integrated 64MB video memory when the system memory is 256M, and when the system memory is increased to 1GB, the video memory will even increase to 565438. Strictly speaking, in the case of the same system memory, the larger the independent video memory means the better the graphics performance of the notebook computer.

3. Notebooks distinguish between licensed parallel imports. Do laptops also play 7. 1 surround? Many merchants can see a laptop using "7. 1" surround sound on the publicity page. This kind of joke is undoubtedly attractive to users who have never been exposed to laptops before, but it is so "7". 1 sound effect "is the function of mainstream integrated sound cards at present, and notebook computers only provide seven." 1 channel sound effects also need enough input interfaces.

4. The "long service life" of notebook computers to distinguish licensed parallel imports is extremely lethal to consumers of mobile applications, but the advertisement also says that "the actual battery service life varies with specific operating conditions and settings". It seems that this explanation is more detailed, and ordinary consumers may not explore it, but many of these labels are data provided by notebook computers in power-saving mode, which has no reference at all. Consumers may wish to pay more attention to the parameters of the same type of laptop battery, such as the number of battery cells, mAh capacity, etc. (mainstream products usually provide 6-cell 4800mAh batteries).

5. There is a mystery to distinguish the warranty period of licensed parallel imports for notebook computers. In order to emphasize that their products have good after-sales service, many brands have printed the words "three-year limited warranty" and added the word "limited" during the warranty period, which is of great significance. In fact, such a "three-year limited warranty" only provides a three-year free warranty for the motherboard of the notebook computer, while the battery, keyboard and display screen that are most prone to problems and wear are only guaranteed for one year. If consumers don't delve into it, it is often easy to misunderstand that this laptop has a three-year comprehensive warranty after-sales service. Therefore, it is only the most obvious misunderstanding in the advertisement of commercial notebook computers. As a vulnerable group, consumers should avoid misunderstandings in advertisements. To do this, they should not only know the basic knowledge of notebook computers often, but also read more and ask more questions when buying them, so they need to shop around.
