Questions about notebook testing. How to test a laptop

Pay attention to the date of appearance Generally appear in 10 20 days normal If it is more than 20 days, it may be a little problematic machine Or if you need it, I have a lot of software to test this book, if you need it, leave a message to me.

In addition to this, I have found some online for you, I hope it will be useful to you:

First of all, see if the seal has been opened.

I was looking at whether the plastic packaging paper in this book had been removed.

There are also buttons, whether there is dust on the computer interface, and whether there are traces of plugging in the touch screen.

It's best to bring a software to see how long the hard disk is used, this software is good hddlife, you can see the time and life that has been used.

BatteryMon can see how the battery is being used.

Good luck.

Just put the optimization master in and put it to the test.

There is no such problem in the new machine, after all, HP is a big brand! Basically, as long as the machine is newly unboxed, it is new, just look at the hardware cultivation inside, there is no need to detect it, in fact, it can't detect anything!

Don't worry, HP is a big brand, the after-sales service is done well, its hardware itself is very good, your worries are redundant, you don't need to do any testing, if you want to test, you can install a Windows optimization master or use everest to test it.

Heat dissipation performance should be the focus of attention.

The heat dissipation performance of the laptop directly affects the working performance of the laptop, and it can also check whether the material of the laptop is good. When checking the heat dissipation, it is best to first plug in the laptop and run it for a period of time, and then feel the temperature of the laptop case with your hands, if you feel hot, then the chosen laptop has a bad heat dissipation effect, and if it lasts for too long, the laptop may crash.

Dead pixel detection, the work that has to be done.

Because the quality of the LCD screen is directly related to the user's visual experience and the service life of the laptop, it is a necessary step to identify the laptop to carefully check whether the laptop display has dead pixels. Dead pixels are actually in a pure black background or pure white background, the LCD has been opaque or has been transparent or even a fixed color of the pixel is called a dead pixel, if the number of dead pixels on the display is more than 5, you can not buy, because over time, the number of dead pixels will be more and more, until the entire display screen can not be displayed normally.

Performance testing is a top priority.

The purpose of checking if the overall performance is good is to verify that the laptop you are currently buying is worth it. When checking, see if the mouse is responsive, whether the trackpad is bright, whether the program is running properly, whether the screen display is clear, whether the laptop is making loud noise when running, and whether the laptop often freezes after a long period of work.

Ancillary equipment, which should never be overlooked.

Since most of the auxiliary devices in laptops have been running for a long time and may lack stable performance, they will fail very frequently when used. Once a fault occurs, it is also more difficult to repair. Because most of the ancillary devices in laptops are old-fashioned, and old-school models are on the verge of extinction in the current laptop market, it is of course difficult to find a match with the old-style ancillary devices; If you replace it with other devices, it may affect the working performance of the entire laptop due to the poor compatibility performance of the laptop, or even make the laptop unable to continue to work.

Therefore, users must check whether auxiliary devices such as keyboards, floppy drives, and optical drives are in good condition one by one.

The accessories are complete and the minimum threshold.

The power supply specifications cannot be taken lightly.

Nowadays, many laptops are foreign brands, for example, many laptops in Japan have a power supply specification of 110V, and such computers obviously cannot be used under the 220V power supply. Therefore, users must verify the specifications of the power supply to avoid unnecessary trouble caused by power supply problems.

Network functionality should also be a concern.

Master Lu can be used for laptop testing.

Master Lu has a built-in hardware test module, which can help users quickly understand the performance of the laptop, which is divided into computer comprehensive performance, CPU speed test, game performance test, display test and performance improvement suggestions. At the end of the test, the software gives a hardware score and usage recommendations, as well as a performance ranking when connected to the Internet.

"Computer Overall Performance" is a test that is often used by users, which can evaluate the computer's file processing, audio-visual**, Internet browsing, and game performance, and will give corresponding results after the evaluation. It should be noted that before the test, please try to close other running irrelevant programs, otherwise the test results may be affected, and the test needs to be carried out in the state of external power supply.

Click on the CPU speed test, you can see that the test items include integer floating-point operation performance, dual-core computing performance, three-core computing performance, four-core computing performance, six-core computing performance and octa-core computing performance.

The results of the game performance test are closely related to the graphics card, Master Lu simulates the game scene to evaluate whether the graphics card can run 3D games smoothly, and 3DMark, the higher the score, the higher the performance of the graphics card.

Depending on the configuration, the test time varies.

No, you first ** Master Lu software, put it in the memory card, when you send the notebook, you send the notebook to install Master Lu, he will help you detect whether it is consistent with the parameters they said: for example: memory size, graphics card model, hard disk size, 、、、 is very simple, this is how I used it this summer!!

Check the packaging, computers, accessories.

Check whether the packaging is damaged, whether the accessories are there, ** there will be a list, Zhang and then look at the computer to see if there is paint off, scratches, fingerprints, dusty potatoes, pay attention to check whether the hinge is loose, if there is a trace of timely feedback to the merchant.

Check the serial number:

Check whether the serial numbers of the body, packaging, battery, and joint warranty certificate are the same.

Detect the screen with Master Lu:

Detect whether the screen is as described by the manufacturer, whether there are dead pixels and bright spots, and if it is an IPS screen, it is normal to have three bright spots or less.

Detect the configuration with Master Lu:

Check whether all the configurations are as described by the manufacturer, and don't worry about comparing the configurations one by one.

Interface check: Test all interfaces of the computer, including the camera and microphone.

If the hard drive is used for less than 55 hours, it is normal.

Use Master Lu to run a score:

If the score does not match the score that should be achieved in the original configuration, you should communicate with the merchant.

Check the network: Check if the network is smooth.

Hello, it is generally impossible to judge intuitively, you can contact the after-sales service station for testing If you are buying a computer, you can provide you with Lenovo computer purchase precautions:

1.Please try to start the computer and test the functions and buttons before taking the machine away to avoid problems;

2.Please try to issue a regular national tax department invoice, Lenovo's warranty calculation depends on the invoice time, there is an invoice that is calculated from the purchase date shown on the invoice, no invoice is based on the production date for repair, in order to avoid your purchase when you are far away from the production date to damage your interests, please let the merchant issue a formal invoice (invoice, not a receipt!) The receipt cannot be used as a proof of purchase and is not recognized and protected by the Three Guarantees Law);

3.Please carefully check the items sent by the machine seal and packing list to avoid inconvenience to your use;

4.Regarding the purchase of Lenovo computers, any items outside the computer carton packaging, such as individually packaged mice, headphones, speakers, USB flash drives and other digital equipment, if they are included with the purchase but not listed in the packing list, please be sure to note that Lenovo does not provide warranty for such items, and you need to confirm the warranty with the dealer, and the failure is generally 1 year to be repaired by the dealer to avoid inconvenience to your use, please be sure to know. \

You're going to buy this? Let me tell you, the Tao in it can't be explained at all in one sentence or two......

"Listen" is to listen to the sound of the machine running, if the sound is very small and stable, and there is no abnormal sound, you can think that there is no problem with the hard disk and fan.

Finally, it is "touch", that is, we must pay attention to the test machine, because as an electronic product, there is no 100% reliability, as a notebook brand that can be seen on the market at present, there is no big difference in quality, but I am afraid of what happens. Generally speaking, if there is no problem with the test machine when buying, it will not be too much of a problem to use in the future. I thought I had to test the machine on the spot, which is commonly known as the oven

The baking machine is mainly to see if there is a big problem with the assembly of the notebook, if the installation fee is not suitable, there will be abnormal sound and heat dissipation is not good, touch the bottom surface of the notebook, if there is a hot feeling, it means that the machine is not good. A mild fever is normal. Generally speaking, baking for more than 20 minutes is enough to explain the problem.

In the end, the book has to depend on your personal favorite.,Because now the book has become more and more fashionable.,It's inconvenient for others to recommend.。
