First, the general view hardware information

For the card, cat, mouse, keyboard and other hardware information can be provided through the operating system’s “Device Manager” to see. Right-click “My Computer”, select “Properties” (which can also click Start “->” Settings “->” Control Panel “->” System open), click on “Hardware” tab, in Device Manager box, click the “Device Manager” in the pop-up set out the window, the computer will be installed on various hardware. For example, we would like to see specific information about the network card, double-click the card icon, showing that your network card installed, right-click and select “Properties” in the subsequent dialog box pops up you can see the name of the device, manufacturers, models, work status and other information, even in the “Advanced” option can also see that the hardware in the occupied system resources and interrupt request. Similarly, mouse, keyboard, modem and other hardware information is also available that view.

Second, view the CPU type and frequency of

As the heart of a computer, CPU type and frequency of performance is directly related to the computer index. Click the “Start” “-> “Run”, type “DxDiag” (without the quotes) and press enter, it will open a “Dirext diagnostic tool”, where the “System Information” in “at the device manager” line to show CPU type and frequency.

Third, view the memory size

Right-click on the “My Computer”, select “Properties” item, in which the “General” column will have the memory size of the show.

Fourth, see the hard disk size

Can be a very “primitive” way to draw hydraulic press hard disk size. Open “My Computer” and then view individual hard drives were the property, the size of the sum of their individual capacity, we can draw the size of the entire hard drive capacity.

Five, check the size of memory

Right click on the desktop, and then in the pop-up menu, select “Properties” then select “Settings “->” Advanced “-> Adapter”, here you can view the memory size of it! Unlike buying laptops to buy other appliances, there is such as Gome, Suning and other very formal shopping malls, most laptops are only sold in computer stores in. For the consumer, will encounter in the store to buy the biggest problem is not regular. If you are unfortunately JS, then we hard-earned money may have been cheated.

Many laptop computer users have purchased a common complaint, to buy back the products that are this or that, or even buy parallel imports, repair the goods, etc., and always a lot of JS to meet state regulations do not give consumers reason to put off change (many state regulations have become obsolete.) In fact, these issues are largely in the testing machine can avoid that hurdle. As long as the good this last hurdle, you can avoid a lot of trouble later, on the one hand they are responsible (thousands or even tens of thousands of not a small sum), on the other hand be able to combat the arrogance of JS, so that they learn what is the integrity of business. The following general testing machine under actual operating procedures and screenshots to give you on:?? First, we must emphasize that no payment before the “customer is God”, that is never established. No matter what you mentioned requirements, such as commitment to non-legitimate demands like dead pixels, JS surely agree. Therefore not completed before the testing machine must remember not to rush to the money paid to JS, or else to have found the problem, “customer is God”, that is not established.

1. The packaging and box items first, check the packaging is complete and correct. Books for many brands, the packaging is sealed. Therefore, whether the first step is to check the packaging to open the scene. Shopping is to buy Tashi, in fact, this is a consumer psychology, and no one wants to just buy a new factory goods, rather than left to pick someone else, or even repairing goods. But there are some consumers do not pay attention in this part, Hu Hu passed Mama, why do this? Purpose is very simple, to prevent the quality problems of products to buy or even repair the goods. For example drawing is opened if the situation encountered in packaging, you may request the replacement of JS, JS this time will make every effort to persuade the general carpet cleaning would be so explained: “Although this model does is open, but in fact there is nothing problem is someone else said, do not open the read …”and so on. To some extent, JS, then there must be some truth, there are indeed some of the books were opened, there is no quality problem, not a repair goods. But how can you ensure that the books opened Taiwan to be no problem, even with the JS in the one-sided? Think about what you buy, but a few thousand or even million dollar laptop ah, but not hundreds of pieces of small appliances, the bet can not afford to play. Therefore I suggest, do not listen to JS’s big talk, straightforward for a new one called him, or leave immediately (you do not give you the money anyway).

Here to remind consumers to pay attention to this situation, some JS extremely treacherous, is packaged in order to eliminate traces of being opened, he would in the original tape and then paste another layer of tape, not looking, do not see a two-tape. After treatment, almost like the new packaging. Been identified as a new not opened the packaging, the take over of the check items inside the box. After unpacking the general notebook computer, in addition to books there is also outside the power adapter, accessories, product manuals, certificates of UNPROFOR (the same ID number and laptop), warranty card, record card, in addition to the operating system installation disk with restore disc (some models not equipped with). So many things, be sure to check them one by one to see if there is no lack, in so doing we can prevent unauthorized JS deducted out of the box accessories, and can further confirm whether this table books were opened box. Inside the box the laptop will have a packing list, even if no separate packing list will be specified in the instructions in the notebook name and quantity of items within the box. Everyone can check the packing list or manual. Also, check whether the operating system installation disk operating system on the machine in line.

2. Check Serial Number

Check the confirmation, the next step is to carefully check your laptop’s serial number. This step is the choice of foreign brands is very important friends laptop, if there is inconsistency in the serial number, there may be parallel or assembling goods. As for the domestic notebook computer, if there is inconsistency, then this notebook computer is opened or is replaced, there may have quality problems or repairing goods. No matter what the situation and immediately called JS replace it. For example drawing?? Check the following to tell us something about how the serial number, serial number, usually appear in these areas: body, battery, outside the box, manuals, certificates and other places of UNPROFOR. Here to explain, not the previously mentioned areas are marked for each serial number, according to each brand differ. Battery, outside the box, manuals, certificates and other UNPROFOR better place to find the serial number, and serial number of the body generally in the base of the notebook chassis. Such as IBM’s ThinkPad notebook computers, the bottom of the machine product model and serial number, the product model ending in the last one is C, said China. Can enjoy a three-year International Warranty, so even out of the country do not have to worry about.

In the check serial number is consistent, we must also check whether it had been altered, are re-posted at the scene, because some powerful little JS to fake the serial number of some of the brand. In addition, some books there is a way to check the serial number, at boot time, entered the notebook’s motherboard BIOS, check the serial number and BIOS serial number of the fuselage are the same. If the marble renovate the serial number are all the same places, then note the source of this basic model does not issue; if there is an inconsistency, then this model does not absolutely have to, the solution is only one word: “change!”

With JS fraud technology increasing, this step must be careful, best to check online or call for more insurance. In short, if they find a little tricky, and must not compromise.

3. Check the Appearance

Visual inspection is necessary because the present practice of electronic products in the country three packs of law, problems can be returned for the definition of the appearance was rather vague, even if they retreat, JS Selection Committee is usually caused by the consumer after purchase nothing to do with him, to the rational can not tell when, in order to avoid face such trouble, so be sure to check the time of purchase the books look. Think about it, buy new books, there is the appearance of the problem, how many will make people unhappy heart.

First check whether the shell scratch, Diaoqi signs, to ensure that shell intact; second look at the shaft with no cracks and loosening of the situation; if it is low-cost machines, but also to check whether there is mold or the side seam is not tight bite the question whether the rough; then check the LCD screen to see if there is no scratching of the situation, because the scratch will affect the visual effects; and then check the keyboard keys, note that there is no side higher than the situation, or there are several key the phenomenon is not flat; the following check shortcut key pad buttons, and multimedia playback, but also note that there is no phenomenon of uneven; last check the battery, pay attention to the fineness of the battery is new, apart from the appearance inspection, need to use a special software testing, I put the back of this talk.

Checked if there is no problem, you can make the following special test for the laptop; if there are problems, the firm called JS-for, I believe that as long as you do not pay at this time, “customer is God”, that is very useful, JS goods will not take no excuse to refuse.

Finally, I would also like to draw attention to this situation, it is bought by a “God *” books of the user at the forum provided by: buy books after the accident found that user the following case even stickers gap appears, then took the books to find replacement JS, JS consumers that this was after buying back caused by improper use, not only to repair to replacement. Thus, for some brands of books, we check to be particularly careful, do not lose a piece of place, or after a problem when the time is more troublesome.

4. The Interface Checks

Visual inspection confirmed that there is no problem, after completion, following the special boot for notebook testing, these tests need to use some professional testing software, so before buying the software ready to put there to bring your U drive. In the bag filter special inspection before the first use of U disk check can be USB, because we often use the USB interface is an interface to, it is best to suggest that you check the check when they purchase USB interface is intact.

The U disk one by one inserted in each of USB interface to see whether the system can read the data inside, ensure that each USB interface to work properly. As for the inspection of other interfaces: audio output interface, only need to bring ear plugs, listen there is no sound on it; the microphone port, then plug in an external microphone, you can check; and S Video, 1394, VGA port, reader, etc., able to do so can bring the appropriate cable and memory card to be checked.

For this step, some people think is not necessary, but personally think is more important, from the perspective of their own responsibility, it should at least check the USB interface.

5. The Detection of the LCD Screen

LCD screen of the special inspection focused on whether the dead pixels on the detection of dead pixels on this we can use NOKIA TEST software to check (see below), this software does not require installation, the file size is only 580KB or so.

Run NOKIA TEST test in COLORS, NOKIA TEST will be given followed by white, red, green, blue, black to detect the screen, we can pass this test to find out whether there are dead pixel LCD screen, here to draw attention to check the time must be careful, especially the small white highlights are difficult to detect. In addition to testing other than dead pixels, NOKIA TEST also detects a lot of projects, such as the geometric image distortion, brightness and contrast, focus, resolution, jitter, text sharpness and so on.

Below can give you about a response time of LCD indirect test software – DisplayX. It can also detect whether the dead pixel LCD screen, the other can breathe effect, 256 gray levels (the better LCD screen display, the 256 gray more obvious) and so on.

LCD screen has dead pixels, just like beautiful face hemorrhoids, how much will destroy the effect of mood, so I stress again to buy other books of special tests can not do it, but the NOKIA TEST or DisplayX sure to bring.

6. CPU Test

Many consumers think that CPU is the most difficult start to cheat JS components, but in fact, some of the JS is the use of consumer psychology, desperate an issue in the BIOS above, the low-frequency processors into high-frequency processors, cheat After the operating system, but also kept a handful of the consumer. In fact, if you have special software testing, JS, these look very childish behavior will be exposed to in your very eyes.

CPU detection tools, the most common CPU-Z is the software, its powerful. CPU-Z does not require installation, the compressed size of only 200 KB, its very detailed CPU detection, we can see next graph:

It should be noted that the issue is best to bring the latest version of CPU-Z software, so that it will not appear on the new processor can not correctly identify the phenomenon.
