What parameters to look at when buying a laptop

1. Choose a well-known brand.

It is best to be an international brand, and the quality of their products is ***, because they are not willing to affect their brand image because of a small market.

2. Try to choose a mobile processor.

The processor is quite the brain of a laptop, and is the most important chip in a laptop, especially the processor will also have a battery management function to extend the life of the battery.

3. The larger the memory, the better.

4 hard disk is preferably 5400 rpm.

The speed of the mainstream laptop hard disk is 5400 rpm, and many low-cost laptops are still 4200 rpm, the faster the speed of the hard disk, the better the overall effect of the laptop, and you can check the model of the laptop hard disk when purchasing, so that you can know the speed of the laptop.

5. LCD screen carefully inspected.

The quality of today's LCD screen panels is generally good, so there is not much difference in brightness, color and sharpness. However, many users tend to only notice the size of the LCD screen, but some signs that are crucial to the display effect. If the viewing angle, contrast, response time, etc. are not enough, special attention should be paid to when purchasing, usually the specifications of the LCD and the actual image quality do not have much to do with it, so if you want to pick a good LCD screen, it is best to see it.

6. Pay attention to the battery.

If the laptop has no battery, the convenience of use will be greatly reduced, as far as the laptop battery is concerned, lithium batteries are now generally used, and they can be charged repeatedly without compromising the performance of the battery, generally speaking, the notebook (regardless of size) provides at least 2 hours of battery life, of course, the longer the better.

7. The workmanship should not be too rough.

Rough workmanship can be said to be a common problem of low-cost computers, many users often only pay attention to the performance of the computer when buying a notebook, but ignore the workmanship, and in fact, the workmanship of the notebook is also a very important link, when choosing, look at the gloss, try the feel, I believe you will make the right choice.

8. The practical value of the included software.

When you buy, look at what software you have sent, but the most important thing is the operating system, ask whether it is a genuine operating system, there may be many laptops that are pirated software installed by dealers, which will bring unnecessary trouble to your after-sales service in the future.

9. Choose high-quality after-sales service.

Notebooks are high-tech products, and their special parts determine that there is no way for individuals to repair them, so choosing after-sales service outlets seems to be the best choice.

It's mostly the CPU

You can't expect the laptop display effect to be high, but the processing effect must be there, the CPU is the key, and the second is.

If the GPU is installed with XP

2G memory is enough, but vista

Be sure to have 4g

In fact, it mainly depends on the CPU and graphics card, and the graphics card is the most important. The heat dissipation of the computer is also important.

It is recommended that you buy a notebook according to your needs, and different needs will focus on different parameters of the notebook.

Office use: It mainly depends on the overall configuration of CPU, memory, graphics card, hard disk, etc.

Playing games: Focus on the CPU of the notebook, the graphics card configuration should be high, the screen refresh rate, the keyboard, the sound effects, etc.

Biased towards 3D modeling, this type of graphics card is better, CPU is as close to i7 as possible within the budget, graphics card GTX1660Ti or above is the best, memory 16G standard, 32G or more is the best.

Buy a laptop depends on what parameters the team leads away and both teams win, Mark is already here with you, Kalu and the two are in.

Buying a laptop depends on what parameters exaggerate the point of losing position, injuries interfere next.

What parameters do you have to look at when you buy a laptop, and I think we will look directly at Hirst in the second half, and Iniesta's problem is like football.

What parameters do you have to see when you buy a laptop, I'll announce the results of the game in advance for God, the director seems to have heard it to a friend, and it's actually a female companion.

Buy a laptop to see which parameters must come up to the state to the first fortress reporter.

The question of buying a laptop to look at what parameters their cold has ever beaten is unstoppable.

Performance and running memory, usually more than 8G running memory is enough.

1. Look at the brand: different brands have different advantages and disadvantages in some characteristics, so the brand is very important, and the brand with high visibility is better than the brand with low visibility in terms of after-sales, maintenance and cost performance.

2. Look at the battery and power adapter: buy lithium batteries as much as possible, and for power adapters, you should pay attention to the abnormal temperature if the temperature is too high after working for a long time.

3. Look at the heat dissipation system: whether the design of the heat dissipation outlet is reasonable, don't open the book will block the air outlet, which will affect the heat dissipation. Try not to have a network cable interface next to the radiator air outlet, as the temperature rises with the lack of it, which may affect the quality of the network.

4. Look at the hard disk: it is best to buy a solid state drive, if there is no solid state drive, then there must be a reserved interface, and you can install it yourself with a reserved interface. For reserved interfaces, the fast interface speed is preferred, and SATA is the lowest choice.

5. Look at the CPU: Don't buy the computer CPU model with the letter U at the end, the CPU performance of the low-power version is worse than that of the ordinary version.
