Are there any books about computer repair?

Computer fault maintenance judgment guidance.

Basic principles that should be followed to carry out computer repairs:

First, the maintenance judgment must start from the simplest things.

Simple things, on the one hand, refer to observation, and on the other hand, to simple environments.

The simple thing is to observe, and it includes:

1. The environment around the computer - location, power supply, connection, other equipment, temperature and humidity, etc.;

2. The phenomena and contents displayed by the computer, and their similarities and differences with normal conditions;

3. The internal environment of the computer - dust, connections, color of the device, shape of the parts, status of the indicator light, etc.;

4. The software and hardware configuration of the computer - what kind of hardware is installed and the use of resources; What kind of application software is installed on the system; Hardware settings, driver versions, etc.

The simple environment includes:

1. The smallest system to be mentioned later;

2. In the judgment environment, only the basic running parts of the software, and the suspected faulty parts of the software;

3. In a clean system, add the user's application (hardware, software) to analyze and judge.

Starting from simple things is conducive to the concentration of energy and the judgment and location of faults. It must be noted that it can only be judged and repaired after careful observation.

2. According to the observed phenomenon, it is necessary to "think before doing".

3. In most computer maintenance judgments, it is necessary to "soft first and then hard:."

Fourth, in the process of maintenance, it is necessary to distinguish the priority and priority, that is, "grasp the main contradiction".

The main thing is to be bold and careful.

Go to the bookstore and buy a copy of the "Motherboard Common Chip and Circuit Repair Manual", there are detailed introductions and instructions, study hard! If the landlord can fully understand and understand the technical information inside, I believe the landlord is also a computer expert! Thank you!

The basics of computer repair, in fact, there are a lot of them on the Internet, so it's good to check them yourself.

I think I'll buy some books about hardware to take the next step and strengthen your understanding of computer hardware. As for the maintenance, I think it is better to find a training point and train it, and if you want to open your own shop, you really still have to go to training, at least you can see which faults are what they are like, and what device is used to detect. If you need to do it yourself, you have to know what kind of equipment you need to do, right?

I have also installed a lot of machines and done maintenance, but I really don't dare to compliment the maintenance, I know what the problem is, but it's really too brainy to repair this. After all, there are too many electronic devices.

You must first understand the structure of the computer and the nursery rhyme parts in the main chassis, and then understand the function of each piece, which is the basis for learning.

Hardware maintenance, the result, is to let you understand the principle of computer execution, component composition, hardware maintenance, hardware characteristics, according to the electronic circuit maintenance, can be extended to other fields in the future, what is needed is to practice, make more use of the existing hardware platform and environment, familiar, practice, learn, and slowly accumulate it.

To put it bluntly, simple learning materials cannot meet the professional of hardware maintenance, but it needs to be practiced.

First go to the computer company to work (at most get some salary), read the computer maintenance book at home, theory and practice at the same time. If you don't go to a computer company, you can't have so many practical opportunities and insights.

If you learn quickly, you will be able to attach it in half a year. At this time, combine the Internet to find someone to ask. Time is accumulation.

I wish you success! If you want to engage in the IT industry in the future and really learn technology, I recommend you to go to a professional school for systematic learning, I studied computer, I studied in Shandong Xinhua Computer College, our school is the largest professional computer college in the province. If you have any questions, you can add my QQ, you can see it if you ask, and I will give you more information to help you!

I hope mine can give you some helpful information!

If you want to do it yourself, you must have the determination not to be afraid of breaking it, and the basic simplicity is okay.

It is difficult to involve circuits and more than chips.

China Computer Repair Network.

It is necessary to start with the basics of the computer, first learn the installation of the computer and the principles of the computer. Installation of software.

Responsible for the management of network wiring and distribution frames to ensure that the wiring is reasonable and orderly; Grasp the internal network connection situation, so that problems can be found and quickly located; Master the connection configuration with the external network, supervise the network communication, and contact the relevant agencies in time after discovering problems; Real-time monitoring of the operation and communication traffic of the entire company or Internet café's internal network.

2. One of the core tasks of the management and maintenance of the operating system of each user is the management of the operating system of the company or Internet café.

This refers to the server's operating system.

In order to ensure that the server operating system works normally, it should be able to use the management software provided by the operating system and from the network to monitor the operation of the system in real time, optimize the system performance, and find and deal with fault signs in time.

If necessary, establish a hot backup of critical server operating systems to avoid fatal failures that can bring the network down.

3. The management of the network application system server is mainly for the management of the functional server that provides services for the company or Internet café.

These servers mainly include: ** Oak server, game server, file server, EPR server, e-mail server, etc.

Familiarize yourself with the hardware and software configuration of the server and make a backup of the software configuration.

The company should manage the normal operation of ERP, prevent errors, monitor e-mail, ensure the company's normal communication business, etc., and the Internet café should update the game software, audio and ** files from time to time to meet the requirements of users.

4. Network security managementNetwork security management should be said to be difficult in network management, and it is a headache for administrators.

Because users may access all kinds of **, and the security awareness is relatively weak, it is inevitable to be infected with the virus.

Once a machine or device is infected, it will have a chain reaction that paralyzes the entire network.

Therefore, it is important to take precautions by setting up firewalls for servers, scanning systems for security vulnerabilities, installing anti-virus software, keeping virus databases up to date, and conducting regular virus scans.

5. The most important data and document management in the computer system of the network should be the data, once the data is lost, the loss will be huge.

Therefore, the file storage and backup management of Internet cafes is to avoid such things from happening in group tours.

The billing data and important network configuration files of the Internet café need to be backed up, which requires mirroring in the storage system of the server to protect the data and perform disaster recovery processing.

Computer maintenance is a very broad term du, which is basically divided into software maintenance

Repair and hardware repair, DAO

The special concept of software maintenance is that everything can be operated by the keyboard and mouse can be troubleshooting, called software maintenance, the scope of software maintenance is also relatively large, definitely not everyone imagines that the ghost system is software maintenance, I often see a lot of "maintenance experts" who are not even rookies open a small shop in ** boast about how high their technical room is, there is a very sad feeling, and hardware maintenance is divided into board-level maintenance and chip-level maintenance, board-level maintenance is a common "maintenance engineer" Through the exchange of diagnostic cards and boards, it is determined that there is a problem with a certain part of the computer, and now many repair shops outside only reach this level.

The highest level of maintenance at the chip level is to achieve the purpose of repair by replacing a certain part or IC, and such benevolence is generally in the computer city, with special equipment and special instruments.

If you want to learn, buy some books on computer assembly and repair first, and then buy some books on computer maintenance to mastery.

There is a premise for repairing a computer: you must have a basic knowledge of English, otherwise you will only stare at the 26 letters.

Hello 1, disassemble and assemble 1 machine by yourself, until you reach proficiency.

2. Internally separate the internal accessories of the computer. That's the CPU, that's the hard disk, and that's the memory module. Take a look at the general distribution of the north and south bridges, and have a general understanding of the interface of the motherboard.

3. Regularly collect all kinds of information on the Internet, and now the information is updated quickly. Learn about the information of each accessory and peripheral equipment, and you will understand a lot about the product after reading more. Regularly visit the computer city, where many staff will be free and enthusiastic to teach a lot of things.

Even if you don't buy anything.

4. Learn more professional books such as analog circuits, microcomputer interfaces, and microcomputer principles. In fact, many books only need to be roughly understood, because many books are used for querying.

5. Collect some circuit diagrams of motherboard maintenance from the Internet, and analyze the circuit diagrams. Just don't know how to ask more, and master the computer boot sequence and computer architecture.

6. Proficient soldering iron soldering, this is a basic skill that no one can teach, and I have done it myself.

The above advice to you is actually so annoying, as long as you have the heart, it is actually very simple.

I've done repairs, but I don't know if you're going to learn soft or hard faults?

Soft Breakdown: Buy some books on computer repair, maintenance, installation, etc.

Hard faults: Buy books on analog circuits, EMI electromagnetic compatibility, electronic components.

It is sold in almost every big bookstore.

Personal suggestion: 1. Disassemble and assemble 1 machine by yourself until you are proficient.

2. Internally separate the internal accessories of the computer. That's the CPU, that's the hard disk, and that's the memory module. Take a look at the general distribution of the north and south bridges, and have a general understanding of the interface of the motherboard.

3. Regularly collect all kinds of information on the Internet, and now the information is updated quickly. Learn about the information of each accessory and peripheral equipment, and you will understand a lot about the product after reading more. Go shopping regularly.

"Computer Assembly and Maintenance Textbook", "Application of Database Technology", "Novice Learning from Scratch Series", and "Computer Enthusiast Semi-Monthly" can all be read selectively.

Practice plus theory, starting from BIOS settings, installing systems, hardware principles, motherboard maintenance, power supply maintenance, there is a lot of knowledge.

1.Those who are halfway through the family need a master to teach them in order to learn professional skills and knowledge.

2.There is no shortest time to learn computer maintenance, only you have accumulated a lot of basic knowledge of electronics, and you also need excellent soldering skills.

3.It is useless to read books, targeted questions and answers, and practical operations, you can remember that it is the shortest time to learn.
