I was going to buy a laptop on National Day, but I didn t know how to verify whether the computer wa

Bring a USB flash drive and find a software to test the hard drive, which has the option to test the use time of the hard drive.

All the new machines were within 72 hours.

First of all, the first step is to select a few target models on the Internet and get a thorough understanding of them. And if you don't buy these ones, this is the first step.

The second step is to unpack it in front of you after you buy it, and if it has been opened, say nothing and don't do anything.

The third step is to turn on the machine, first ** the computer, whether there is a handprint, including the appearance, the screen. There are also scratches on the computer anti-theft lock. Then listen to the sound of the computer working, whether there is any noise.

The fourth step is to turn on the machine, detect the working condition of the power supply (do not connect the battery first), check whether the system has the various settings required for the first start, if it directly enters the system, it means that it is not a new machine.

Step 5, check the sound, screen, whether the sound is clear, and whether there is any noise. Whether the screen has bright spots, dead pixels, or improper colors.

Step 6: Bring a CPU-Z software to see if the detected hardware is the same as the standard configuration.

If everything is in order, pack up and go home.

During the National Day, there are many people in major stores, and merchants have psychological advantages.

Buying a computer should not be a one-time deal, shop around.

Choose a brand computer.

Take two friends with you.

This question is more specific and troublesome. Hehe, but I can tell you about them one by one. Some say check the seal before unpacking, which is honestly not very safe.

Now the renminbi can be forged so realistically, let alone your note? But it's good to check it out. Next comes the most important thing.

Before opening the box, you must tell the seller that if there is an old machine, replace it with a new one immediately. Otherwise, some traitors will deduct your 100 deposit (the deposit is what you need to pay when you ask him to pick up the machine and open the box). After unpacking, check the packing list and check the contents of the box.

Check whether the packaging of the machine has been dismantled, the floor pad can not be dusty, the battery contacts are not scratched, and the keyhole of the notebook is not scratched. Open the notebook, whether there are scratches on the screen, whether there is dust between the keyboards. After everything is ok, turn on the power and start the system.

Listen carefully to the sound inside the machine, the hard disk should run without noise, and the fan should not be harsh. You can put your hand on the air outlet when you turn it on, and there is a cool breeze coming out. Let the merchant install the system for you, and after installation, you can use a USB flash drive to copy a Master Lu to install it and test the hardware.

Note: When detecting, do not let the merchant plug in any mobile device to prevent some software from tampering with the hardware information. The hard disk should run for no more than 10 hours, and the hardware parameters should be able to match the configuration order. Finally, check the screen dead pixels, there should be no more than 3.

Master Lu has a screen detection program on it. The above is my experience of buying a small y. Whew....It's finally over, all by hand!

I hope it can help you, and I wish you to buy your favorite Benbenha as soon as possible! Appreciate!

Your next Master Lu, just look at the use time of the hard disk, generally speaking, the use time of the new computer hard disk is about 10 hours, because the factory has to run the test!

It is best to use a professional tool to detect the hard drive usage time and the production time of some hardware.

Go online to the official ** for mobile phone registration, you can register to find out the new and old computer and the date of manufacture.

Pro-orange Bu, you can check whether the newly bought laptop is ** through the following ways: 1Official channel purchase:

Buying a laptop from an official or authorized sales channel can ensure the quality of the product. Some large e-commerce platforms and physical stores are also officially authorized sales channels. 2.

Check for security marks: Many notebook brands will come with security marks. You can verify that the product is ** by scanning or entering the anti-counterfeiting code.

When buying a laptop, the product's box, accessories, and user manual, etc., should be complete. If something is missing, then there is a high probability that it is a counterfeit. 4.

Observe the appearance quality: Laptops usually have a more refined appearance and better workmanship. If the exterior is rough and not refined, then it may be a counterfeit product.

In short, when buying a ** laptop, you should choose the official channel to buy it and check it through the above methods. If you are still worried about buying counterfeit products, it is recommended to find an after-sales service center authorized by the brand or after-sales ** Yuan Wusui for consultation.

First, unpack and check.

Especially for notebooks purchased online, the goods must be inspected in front of the courier when they are received. This check is mainly in terms of appearance, such as whether the appearance of the notebook is bumped, whether all labels are in good condition, whether all wires are intact, and whether all screws have been removed.

2. System and software and hardware.

New notebooks and brand machines come with genuine systems, so after booting up, it should be several configuration interfaces of the system, and then enter the desktop.

Once you're on the desktop, the first thing you need to do is check that the hardware configuration matches your choice: right-click on the PC and select Properties View.

How to properly use a new laptop battery:

1.Newly bought laptops do not need to be activated, and the first three 12 hours do not need to be charged. The battery is designed with power protection, so it is impossible to run out of power completely, and it is certainly not possible to overcharge.

2.The lifespan of a laptop battery is greatly affected by the surrounding environment. It's best to keep your computer in an environment between 25 and 40 degrees.

If you want to leave the battery for a long time, it should be placed in a dry and low temperature environment, and the remaining capacity of the battery should reach about half. Generally, you can take it out and charge it once every month or so.

3.The larger the battery capacity, the better. Generally speaking, the larger the capacity, the shorter the lifespan of the battery. Batteries have a limited cycle life, typically only a few hundred cycles.

However, it is not the number of charges, but the number of complete discharges. That is to say, when a second-hand notebook is plugged into an external power supply in the battery compartment, and the remaining power is 95%, the battery will be charged once to 100%, which is not counted. You have to do this 20 times, adding up to 100% charge, and after a full charge it's a full cycle.

Therefore, it is not correct to completely use up the battery and then recharge it, and it will also damage the battery.

The method of inspecting the newly bought notebook: observe the outer packaging box, observe the appearance of the notebook's peripheral, query the serial number, observe the first screen after booting, query the number of times the computer comes with the hard disk and the time of use, etc.

1. Observe the crack of the outer packaging box.

If the outer packaging is damaged and the mortgage is deformed, the machine inside may also be damaged; Or the outer packaging is a second tape encapsulation, such as not the original packaging tape, in this case, it is possible that the machine is no longer a new computer.

2. Observe the appearance of the surrounding area of the notebook.

Generally, new computers will not have appearance wear or bumps. At the same time, you can see if the screws on the back cover have been unscrewed, and generally when the screws are unscrewed, there will be traces of screwing. Check whether there is any prying in the gap in the middle of the plastic shell, or if it is damaged.

3. Query the serial number.

Enter the serial number into the official ** of the notebook to check what time the notebook left the factory, if the time is too early, such as half a year or even more than a year, then this notebook is likely to be a stock machine. And you can also check whether this machine is in a state of repair through customer service.

4. Observe the first screen you enter after booting.

Generally, the boot interface of the original factory computer is the initial interface of the Windows system, rather than entering the desktop state of the system. If the boot is the system desktop, then the system is likely to have been used by others. Or the manufacturer later installed the system and also entered the desktop system at the same time.

What should I pay attention to when I buy a new notebook:

1. Ask for an invoice.

If you buy a new laptop, don't open it after buying it, but ask the merchant to issue an invoice, whether it's an offline or online purchase, remember to ask for a bad invoice, even if you can't get the invoice immediately, you have to let the other party make a commitment, and this is the most powerful proof of purchase.

2. Prepare before starting.

If it is a laptop purchased online, if the user is a northerner, the weather becomes colder, and the computer transported outdoors will be in a low temperature state, if it is disassembled immediately after receiving the goods, there will be a slow frost phenomenon under the effect of indoor high temperature, and this can easily lead to a short circuit inside the laptop because of the water mist, which needs to be placed in a warm indoor environment for 3 5 hours before turning on.

First of all, go to the official website and download the crystaldiskinfo software, put it in a USB flash drive, and then install it on a new computer. (Put it in the U disk, it is convenient to go to ** direct inspection machine.) Just install it with the installation instructions.

First, use the computer manager hardware test to carry out hardware testing, mainly to see whether the hardware is consistent with the product promotion.

Then look at the health of the hardware, mainly depending on the number of times the hard disk is used, about 50 times of use is considered a new machine.

Then look at the hard disk information, if you have a solid state drive, you should see if the specific parameters are consistent with the advertisement, and there are also the number of times the hard disk is used.

Finally, the key battery information, the battery loss of the new computer should be less than 10%, and if you reach or exceed this threshold, you can directly request to be replaced.

CrystalDiskInfo software is a software that specializes in detecting hard disks and can determine the status of hard disks. The power-on time and the number of power-on times are the points that need to be paid attention to, and the time is not more than 30 hours for the new machine.

When buying, carefully inspect the laptop box, if the box is open or too worn, the computer is likely to be counterfeit or refurbished.

2.After opening the package, check the box, whether the serial number on the back of the computer and the inside of the computer are the same.

3.Check the screen of the notebook, whether there are scratches or dead pixels (the country allows three dead pixels) Check the screws of the computer, whether they are the same everywhere, the general dismantling will be seen from the screws, the paint on the screws will be damaged, or the screws will be worn.

The packaging is the most likely to be faked, mainly to look at the serial code packaging box, on the computer, on the quality insurance policy, three codes in one is basically no problem, in the auxiliary Lu master to confirm the configuration, there are hardware configuration labels under the computer keyboard, the most important thing is the brand, small brands and miscellaneous brands are not easy to confirm, big brands rarely have problems, generally in the hardware configuration to fool you, useful please adopt.

Just give a reason, get the after-sales service and repair it, it's not that he doesn't give a warranty.

In addition, you bought it **, is it so risky? I've bought 5 notebooks, and I really haven't worried about this kind of problem. In the first few times, I will take the invoice and after-sales service card to register online, and the back will not be ignored at all.

The next hardware query software, a lot, 360, drive life ......There are also foreign ones, but if you are a novice, it is recommended that you use domestic 360 hardware monitoring, which has the number of times the hard disk is used. The number of times the battery has been used. The configuration of each hardware is clear at a glance, and you can know if it is the same as the manual.

Check the serial number, the official website of the computer, or call ** past, the serial number is generally in the battery. Then use the software to watch it.

There is a serial number in the battery slot, check it on the official website.

There is an original barcode behind each brand computer, and there should be a place for barcode verification on their official website.

Check the serial number, the official website of the computer, or call ** past, the serial number is generally in the battery, or pasted nearby.

Use Master Lu to test your computer hardware, and then look at the factory date and power-up time.

The notebook cannot be detected, and can only trust the credibility of the purchase channel you choose.

The easiest way to do this is to ask for an unopened notebook when you buy it, and the unopened notebook will have a smell when it is opened, which is only available on computers that have not been shipped out of the factory for a short time and have not been opened. This way you can confirm that it is original**.

If you have already bought it, first use the commonly used hardware check and score tool to detect; Check the configuration on the official website to see if the configuration is consistent.

If you are still not at ease, you can directly take it to the after-sales center to check, that is, the computer often shuts down automatically for unknown reasons, and the after-sales personnel will help you detect it. If there is no problem with the detection, it should be original.

Before unpacking the box, you must pay attention to check whether the box is in good condition, sometimes the box is not always damaged, but the warehouse moisture, improper transportation may cause damage to the product. Look at the seal, check the model is the basic work before unpacking, verify that it is correct before you can open the seal, do not wait until you open the box to find that the merchant "took the wrong" machine, buy the match but become a low or high configuration, to the bad business to transform, check the random accessories, check all the random accessories of the notebook is very necessary, these accessories mainly include drive discs, manuals, warranty cards, etc., because the merchant in the ** refurbishment of laptops, it is difficult to collect these accessories completely, especially the product manual, It is generally printed by itself and is easily recognizable. If these accessories are not complete, the notebook may be refurbished.
