Exposure to fraudulently exchange components

Setting the profit target to the top, many dealers and stores, laptop business companies have sought to "trim" parts before selling to users.

The article only raises a small aspect with the currently applied method in the laptop market today, mainly to confuse the ability of users to analyze and comment on products.

Ignore the black cheating

Usually desktop systems (desktops) are configured in a fairly clear way, especially for reputable brands, perhaps because with desktops, users can easily check the correct information. specs.

Ignoring that, the problem here is in the market, with the same product model, but there are many different configurations and prices between stores and retail IT companies.

Sometimes the difference is said to be dodged, 'ignoring the black' and only until after a period of use, thoroughly examine the user who knows he has bought it or is not entitled to the right policies from genuine for components and devices I have purchased such as warranty, promotion, technical support . There are two ways to 'turn' components mainly or used by sales places:

1. Exchange of components : New technologies are always more expensive than old ones. Imagine changing a standard Wi-Fi board N (price ~ 1.00USD) with a standard Wi-Fi board G (price ~ 50USD), the difference is that the user benefits or the place of sale ?! The more expensive components have been changed and so is the cheaper product that few experienced users know about this change.

More specifically : a laptop configured as a 7200 rpm hard drive or Wi-Fi N board or DVD-RW drive, but when a user acquires a 5400 rpm or Wi-Fi G hard drive or optical drive, it is only DVD-CDRW combo drive. Of course, the difference in value has been lost to the place where sales are 'not good'.

You should know :

- DVD-RW drives cost ~ 60-80USD, while DVD / CD-RW combo drives cost only ~ 30-40USD.

- 320GB HDD 7200rpm / 16MB cache costs ~ 100-120USD, while 320GB HDD 5400rpm / 8MB cache costs only ~ 60-70USD.

- Standard Wi-Fi board G costs only 15-25USD while for standard N you will have to spend no less than 40USD.

2. Remove components : Bluetooth board or RAM are components that are often removed or exchanged. With RAM, the growing demand from users makes low-capacity RAM prices very low, if they are removed or replaced, the user has just suffered material damage and the ability to upgrade later. when demand is higher.

For example, the standard configuration of a system is 1GB of RAM, but the price of 1GB RAM is sometimes four times higher than 512MB of RAM. So, just by attaching 512MB RAM to the system with 1GB RAM configuration, the place of sale has a little difference, the user will need to upgrade later to take advantage of old RAM sticks (usually laptops only have two RAM slots) and waste are inevitable. This is often on quotations that are not shown, so it is difficult for users to identify.

With the Bluetooth board, the removal is easy and quick. Not many users are interested in this issue, so when it comes to it sometimes it takes a lot of money to buy such a board.

You should know :

- Price of 512MB RAM (DDR2, 533-667MHz) is only ~ VND 50,000 while the 1GB bar will be at least VND 200,000.

- Built-in Bluetooth board costs at least ~ 15-25USD.

Why do writers do not mention CPUs - the previous component is often changed a lot? Currently, the supply of removable mobile CPUs in the external market is quite limited, accompanied by high risks. Therefore, at the present time, exchanging CPUs in new machines is very small and usually only when the user brings the machine to repair or speak more cruelly than . boiled.

Solution

The fastest way to correctly check a laptop's specs is to go to the manufacturer's website with the information you need: the model or serial number, service tag .

Exposure to fraudulently exchange components Picture 2 • Optical drive : Check carefully between the actual product and the information on the quote, the external inspection is not difficult between the seller and the buyer, so ask the seller to check carefully. .

• Hard drive : Usually the hard drive's secondary parameters are not informed on the quotation, so there is only one way to check this parameter in advance to access the manufacturer's website and with the actual product Ask the seller to guarantee you this information.

Why ask the seller to guarantee you? In fact, only once a laptop has been sold, can the new vendor 'extract the win' and then you can check the exact specifications. So imagine if the place of sale does not accept the information you have!

For example, the usual DELL Latitude E6400 laptop is equipped with a 7200rpm 16MB HDD 80GB SATA2 cache, but if your laptop's hard drive is only 5400rpm / 8MB cache only? In fact, the performance difference between 7200rpm / 16MB cache and 5400rpm / 8MB cache is very much. Moreover, the price of these two drives is at least 30% different and it is not always possible to buy 'VIP' hard drives with such high specifications and quality from the outside market. .

• Wi-Fi board : Of course, the information about any standard Wi-Fi board will be shown on the quotation, but it will still need to be checked correctly. The advantage of loopholes is that the number of standard Wi-Fi AP / Router is not so many, so users often find it difficult to know exactly what their Wi-Fi standard, many places have changed this part.

After having accurate hardware information from the company, users will have to use the system's hardware information checker software to know exactly what type of Wi-Fi board they have.

• RAM : There is no feasible solution, it is best to ask the salesperson to know how many RAM slots are available for the laptop you are planning to buy and how much slot (slot) is left!

• Bluetooth board : After entering the operating system, users can go to Device Manager to check information about bluetooth devices. Usually it will be in the Network adapters section.

All solutions are needed in the process of checking to make sure not to buy the wrong product as it should. In addition, you also need to select reputable sales places and go with experienced friends who can advise or check for you in case of need.
