Many people asked on the headlines, what should people pay attention to when buying a computer? How to choose a computer when buying one? Which brand to buy? Which model should I buy? Let me share my opinions based on my many years of maintenance experience for your reference.

I have been in charge of IT work for more than 20 years since I started working. The desktop computers and laptop computers used in daily office work of our company have always been purchased by the group company in Shanghai. The winning bidder will then distribute the computers to each branch. The following is Let’s talk about the differences between the different brands we have used.

1. Product quality

Among the three brands we usually use, Dell, Lenovo, and HP, Dell has relatively stable product quality, followed by HP and Lenovo.2. After-sales service

Dell and HP's after-sales service is based on door-to-door service by engineers, while Lenovo's after-sales service is on-site repair. Faulty equipment or machines must be sent to designated repair points.

3. System compatibility

Dell has the best compatibility. In more than 20 years of application, there has been no problem of software and hardware incompatibility, but Lenovo and HP are second. In the era of win98 and XP, blue screens occurred frequently, but Dell did not have many blue screens.

4. System stability

Since Dell's drivers are provided by Microsoft, the compatibility and stability are the best. However, Lenovo and HP write their own drivers, and sometimes compatibility issues may arise when switching between old and new systems.

5. The current operating system is win10. The Dell machine we used has never had compatibility problems, but an HP laptop last year had constant problems.

In March last year, we received a batch of HP notebooks. This notebook had troubled us for a long time due to the incompatibility of its driver files with the win10 system security patch.

The process is as follows: After using this notebook for a period of time, the user's machine turned off and the patch update was normal, but when the patch update was turned on, the machine failed and a blue screen appeared at startup, as shown in the picture below:

After a failure, no matter whether you repair the computer program, restore the computer through restore points, restore the computer to its factory state, or use hidden partitions to restore the system, you cannot return to normal.

There was really nothing I could do, so I called the manufacturer’s 400 number, and the after-sales staff gave the following reply:

1. Do not turn on the security patch update function

When using this notebook, do not turn on security patch updates, otherwise this problem will occur when updating to a certain security patch. Currently, the manufacturer has no complete fix.

2. Reinstall the system to solve the problem

Users go to the Microsoft website to download the latest 10 installation program. After reinstalling the system, they go to the manufacturer's website to download the latest win10 driver for this notebook, and then it can be used normally. However, it is still recommended that users do not turn on the security patch update function temporarily to prevent this situation from happening again.

3. Cause of the problem

After repeatedly questioning the technical engineer, he said that it was caused by a conflict between a certain driver of this notebook and Microsoft's security patch.

What is the solution? If you want to use the system normally, you have to turn off the system's security patch updates. So who is responsible for the security of the system?

6. Dell computers support the installation of multiple genuine operating systems

We discovered this pattern in 2000. Using the operating system CD that comes with Dell computers, you can install it on any model of Dell computer and automatically activate the operating system.

It is recommended that Dell computers at work or at home install genuine operating systems. After installation, Dell computers connected to the Internet will automatically activate the genuine system.

I hope that everyone will not download and install various so-called clean and pure systems on the Internet for convenience. All of these images contain viruses, Trojans or rogue software, which not only reduces the performance of the machine, but also brings endless security risks. . .

7. It is not recommended to buy assembled computers

1. Assembling a computer no longer saves money

Around 2000, assembling a computer could save more than 1,000 yuan compared with buying a brand-name machine. At that time, everyone bought assembled computers. But now if you want to buy a computer, you can log in to the online shopping platform of a certain large e-commerce company. You will find that the cost of assembling a computer is about the same as buying a branded computer in a large shopping mall, so it is not necessary to buy an assembled computer. Save money again.

2. There is no guarantee of after-sales service for assembled computers.

Branded computers enjoy after-sales protection during the warranty period. However, there are many after-sales problems with assembled computers, such as businesses going bankrupt, changing their names, or making excuses not to provide maintenance. There are many such examples.

3. The quality of assembled computer parts cannot be guaranteed

The first step in assembling a computer is to negotiate the order. During the conversation with you, if the merchant learns that you don’t understand computers, you will have fallen into a scam. They will pass off inferior products and quote high prices at low prices. While making profits, the computers assembled with old, inferior and off-brand parts are not only not worth the money, but also create hidden dangers for the stability of the system.

The above is my experience over the years. Please add any inaccuracies. I hope it can provide some inspiration and help to those who want to buy a computer.
