Used computers's deception 1. Modify the display of hardware information. Through the function of WINDOWS theme pack, use special theme pack or software to modify the hardware information display of "My Computer", including memory, CPU, graphics card, etc. (For example, the actual memory is 128M, and the modified memory is displayed as 1G or 2G, etc. ), the information reflected during normal viewing is inconsistent with the real thing. 2. Refurbishers usually, the newer the notebook color, the less time it takes and the higher the price. So many profiteers like to sell refurbished machines, because the profit is the biggest. At present, most of the so-called low-equipped prototypes and inventory machines on the market are refurbished laptops. But as long as you check carefully, you can't say that 100% is accurate, but you can basically find those people who are "beautiful" in Gui Li. 3. Confusing model parameters The model configuration of second-hand notebooks is very complicated. The product configuration of the same series often differs a lot, and the price difference is also great. Profiteers often use the complexity of the model to deceive some consumers who don't know how to do it. 4. Deliberately confuse the price. Many friends may wonder that the price difference of second-hand laptops with similar colors and configurations is considerable. This is an important way for profiteers to make money. The profiteer deliberately messed up the price, which is still one. For example, if you choose a computer, you will find that one is particularly cheap and the inspection is no problem. However, in the process of communicating with the boss, the boss "inadvertently" revealed that his machine was not the main product, and the cost performance was higher, so you bought the one he recommended, and went back to check that the price was much higher than the market price or there was something wrong with the quality. 5. Online second-hand transaction fraud Online second-hand notebook transactions have broken the time and space restrictions, and the product categories are also very rich, with high grades and attractive prices. Sellers are often in other cities, so it is difficult to inspect the goods and the risk is greater when buying. 6. Liars who recycle old computers. These swindlers usually ride a tricycle with two computers on it, telling you where they just recycle it at a very low price and then sell it to the second-hand market. If you turn on the computer and see that it is relatively new, you will be cheated immediately because you think it is cheap. He won't be your interview machine, because the machine won't run; None of the hardware in it can be used, it's all patchwork. If friends know a lot about computers, bringing friends is the best way. If not, you can only rely on yourself. As for the means used by swindlers in used computers, we can see through them in the following ways. First: master the second-hand market situation. Before departure, you should know the internal configuration of the chassis, and understand the current market situation and main performance of the buyer. The easiest way is to find the relevant accessories of the buyer online, look at the evaluation and price of these accessories online, and estimate the price according to the time that the buyer has used. If the estimated price is too different from the price of the target commodity, be careful to be fooled. Second: carefully distinguish the old and new parts. From the old and new degree of accessories, the approximate service life of accessories can be estimated. After buying second-hand products, merchants usually simply renovate, hoping to get more profits in this way, so users should pay attention to checking the old and new hardware. By observing the amount of dust in the capacitor gap and the wear of circuit board pins, the service time can be estimated. In addition, pay attention to check whether the accessories have been repaired, otherwise it is possible to buy the repaired goods. In fact, it is very simple to identify the return, that is, carefully check and observe whether there is repair welding or virtual welding on the hardware, and whether the chip model is inconsistent with the introduction. Third, sellers with system disks use special theme packages or software to modify the hardware information display of "My Computer" through the function of WINDOWS theme packages, including memory, CPU, graphics card, etc. (For example, the actual memory is 128M, and the modified memory is displayed as 1G or 2G, etc. ), the information reflected during normal viewing is inconsistent with the real thing. Bring your own system disk, make your own system for the target computer, and then check the computer properties, maybe there will be changes. Although troublesome, it is very useful. Fourth: bring test software. If you still feel uneasy, take out our test software. The test software is heartless. It is clear at a glance whether it is a dragon or a snake when it runs. These softwares can generally be downloaded from relevant websites, and can also be found through online search. Just put it on a USB flash drive and carry it with you. Recommend Master Lu. Fifth: Ask for invoices and receipts. If everything is all right, remember to ask for invoices and receipts, because invoices and receipts are the only proof of computer warranty and ordinary users can't lose them. If the seller can't provide these, then this person is probably a vendor. Quanzhou computer recycling
