What do you need to do something at a computer repair shop 100?

Make a little supplement of computer science knowledge by yourself, so that it is convenient to introduce your computer problems to the maintenance personnel in detail.

Back up your files. The maintenance staff may reinstall the system for you, or maybe they will replace the hard disk for you, and I have encountered the problem of not asking me before reinstalling the system, resulting in the loss of many of my important files.

Learn to say no. I went to fix my computer, and the seller gave me "advice" to install and replace the hardware in order to make more money, but I refused because I didn't need it at all. At that time, he didn't prescribe the right medicine, and he saw the big from the small. But to believe that there are still many good people in society!

, bring the invoice (if the original online purchase invoice is office supplies, some brands need to show a detailed invoice). Back up your computer. Make a list of parts.

2. After-sales repair of computers, most manufacturers will be more formal, but occasionally there will be repairs to this other faulty frame.

3. For example, if your graphics card is broken, take it and repair it, and come back to find that the graphics card is good, Bluetooth, and the touchpad are not working, and this kind of phenomenon also happens from time to time. So go to after-sales, be sure to pay attention to this kind of problem!

4. There is basically no need to worry about being stolen to change parts, and big brands rarely happen!

The most important thing is the data, and the data is the most important. You first ask, how will he deal with it, how much money will be processed before processing, what effect will it have, and so on. Don't leave anything behind.

1. In the process of reproducing fault phenomena and judging maintenance, the expansion of the scope of faults should be avoided;

2. During maintenance, the packing list and configuration must be checked and checked;

Third, it is necessary to communicate with users adequately. Understand the user's operation process, the operation performed in the event of a malfunction, and the level of the user's use of the computer.

Fourth, the first thing to pay attention to in maintenance is observation - observation, observation, and observation!!

Surrounding environment: power supply environment, other high-power electrical appliances, electricity, magnetic field conditions, machine layout, network hardware environment, temperature and humidity, cleanliness of the environment; Whether the countertop on which the computer is placed is stable. Whether the peripheral equipment has abnormal phenomena such as deformation, discoloration, and peculiar smell;

Hardware environment: the cleanliness, temperature and humidity in the chassis, the jumper settings, color, shape, smell, etc., and whether the connection between the devices is correct; Whether there is any error or misconnection, missing needle, broken needle, etc.; Other equipment connected to the machine installed by the user, and all other hardware facilities that may be related to the operation of the machine;

Software Environment: aWhat kind of software is loaded in the system, and whether there is any conflict or mismatch between it and other software and hardware;

b.In addition to the standard software and settings, it is necessary to observe whether the drivers and patches of the device, motherboard and system are installed and appropriate. whether the fault to be dealt with is an industry-recognized bug or compatibility issue; Whether the other applications and configurations installed by the user are suitable;

Observation during power-up: temperature, peculiar smell, smoke, etc. of components; whether the system time is correct;

Observation when disassembling and reconstructing: It is necessary to have a good habit of recording the original installation state of Caining, and carefully observe the shape, color, and original installation state of the components on Caining;

Observe the user's operation process and habits, and whether they meet the requirements.

First of all, the service attitude must be good, which is a standard for whether you can become their employer, and it is best to mingle with the following employees.

Software and hardware failures can be repaired one by one, and detailed records are made easy to settle accounts.

It is best to have someone from their company present to supervise the repairs and answer all questions.

If you can talk to their boss about how much the all-inclusive software will cost next year, and the hardware will be charged separately, then you will be able to do it.

Data recovery technology must be in place because a lot of their data is irreversible.

Make a backup with ghost before repairing, and you can also restore it to an accident state in case something happens, just in case!!

For this kind of enterprise users, they must repeatedly let them determine the location of the data and copy the data out If the hard disk is damaged and the data cannot be copied, explain it to them clearly and do not move the computer to prevent it from being unclear when the time comes.
