How to repair your laptop without being hacked

Many friends have finally bought a laptop that satisfies them by checking quotations online and visiting forums. They thought they could enjoy the convenience brought by the new computer, but due to the rampant Internet viruses, The proliferation of rogue software, coupled with insufficient protection of your laptop, can cause some computer malfunctions, thus affecting your use. And a malfunctioning laptop gives profiteers an opportunity.

At present, laptop computer failures can be divided into software failures and hardware failures. There are also many pitfalls in the process of sending them for repair. Let's talk about how to deal with the computer failure.

Viruses and rogue software damage

Viruses and rogue software are the fastest spreading software on the Internet today. Both of them can seriously slow down the system or destroy data and cause the system to crash. . Ordinary users are often at a loss when encountering this kind of situation. The solution usually adopted by dealers for this kind of failure is to reinstall the system. This solution does not address the root cause. For boot-type viruses, sometimes reinstalling the system cannot solve the problem.

Countermeasures: Dealers will usually help users deal with this kind of fault during the warranty period, but sometimes the handling methods are not appropriate. We should frequently upgrade the virus database of the anti-virus software and use Security Guard 360 and other methods to remove rogue software. Tools to keep your computer safe and efficient. If there is a special situation, such as anti-virus software causing a system crash, and there is important data on the hard disk, do not reinstall the system immediately. Instead, find a way or ask a professional to back up the important data before considering reinstalling the system.

Data Recovery

Many business people are accustomed to storing important data in their laptops. This is safer, but once there is virus interference or someone deliberately destroys it, it will cause Loss of important data requires the use of certain technical means for data recovery.

There are some data recovery software available for download on the Internet, but in fact, when the data is very important and the situation is complicated, we still do not recommend recovering the data by yourself, because recovering the data by yourself is likely to cause secondary damage. damage, causing data to be unrecoverable.

For data loss caused by mispartitioning, misformatting, misdeletion, MBR loss, BOOT sector loss, misoperation, RAID array failure and other factors, it is not difficult to recover hard disk data, and the fee is not It’s too high, but we’d better find a professional data recovery center to operate it, otherwise the data will also be damaged twice.

It is difficult to recover Office series Word, Excel, Access, PowerPoint files, MicrosoftSQL database recovery, Oracle database file recovery, Foxbase/pro database file recovery, damaged MPEG, asf, RM and other media files. If there is a broken link in the file, it may not be 100% recoverable.

Disk body failure: burnt magnetic head, aging magnetic head, damaged magnetic head chip, magnetic head offset, scratched disk, deformed magnetic group. These hardware failures cause the most difficult data loss and recovery, and the charges are relatively high. , the data cannot be fully restored in such situations.

Countermeasures: After data is lost, you must first make a judgment yourself whether it is a hardware problem or a software problem. If the problem is caused by accidental deletion, partitioning, or formatting, you should stop all disk writing operations and hand it over to professionals; if it is a hardware failure, such as abnormal noise in the hard disk, you should not try to read repeatedly or use software to restore it, so as not to cause damage to the disk. Serious physical damage to the body.

We should choose a professional data recovery center with clearly marked prices, and we need to have a simple understanding of its operation process. For the recovery of important data in a RAID disk array, the correct approach is to mirror first and then perform the disk mirroring operation.

During the warranty period

Many well-known international brands provide free services for their notebook products during the warranty period. For general non-human faults, officially authorized repair centers provide free repairs. Users save a lot of trouble. But there are also some details that everyone needs to pay attention to.

Even officially authorized repair centers have irregularities

1. The laptop fails when the warranty period is about to end, and the person involved is unable to send the computer for repair in time. For example, we are out of town. .

Countermeasures: At this time, we can register with the local Consumers Association. This certificate is generally valid. When we send it to the repair center outside the warranty, we should also receive warranty treatment during the warranty period.

2. Some laptops have some problems that come and go. One of my friend's laptops once had the problem of no display on the startup screen. It was within the warranty period and was sent to the maintenance center technician for repair. After shaking the screen several times, the screen returned to display. The technician said that the cable was loose and suggested that the cable be replaced when it completely failed. The screen could be replaced free of charge during the warranty period. Half a year later, the screen really stopped lighting up at all, but the warranty period had expired, and repairs would cost more than 3,000 yuan.

Countermeasures: We have two ways to deal with this kind of situation. First, don’t take chances. If there are good and bad problems, don’t delay if it is within the warranty period; second, if it really cannot be done at that time, If the computer is left in the repair center for too long, ask the maintenance engineer to issue a maintenance record. The reason for the failure and the solution should be clearly written on it. This can also be used as very strong evidence to request free repair when the warranty expires in the future.

3. During the process of sending it for repair, it will inevitably cause wear and tear on the surface of the notebook, and even cause new damage. These manufacturers think of it before users do, and generally have similar exemption provisions in their maintenance clauses.

Countermeasures: When we send a laptop for repair, we must bring packaging to prevent computer wear and tear. Ask what accessories are not needed for repair. Take away everything you can, such as hard drives and batteries. These accessories repair centers Users are allowed to take away. At the same time, you must also read the maintenance terms clearly. If you have special requirements, you can add items to the additional terms.

Outside of the warranty period

1. Choose a reputable and large-scale repair center

At this time, we do not recommend that you go to the official repair center for repair. Because the charges are too expensive, and some minor problems are repaired as major problems. For example, if the screen cable is damaged, you can directly replace the screen, which will cost 3,000 yuan or more.

Not many can perform chip-level repairs

There are also many things to pay attention to when repairing computers at specialized computer repair departments with good reputations. Some people think that large and formal repair shops charge expensive fees, but this is not the case. Some small stores cannot repair faults with any technical content themselves. They outsource these computers to large repair centers to make a profit on the price difference, because they have already been ripped off by large repair centers once, and consumers repairing them here is considered a second time. Being ripped off, so the cost is higher.

2. Overhaul of minor problems

Overhaul of minor problems is one of the most effective and unfair means of making money in the maintenance industry. Customers who don’t have much knowledge about computer repairs don’t have many options for this. . But before we send it for repair, it is best to use a digital camera to record it. If you can remove the accessory yourself, take photos of the details of the accessory for comparison after repair.

After the repair is completed, it is best to ask the cause of the failure to avoid wasting money. We once encountered the phenomenon that the optical drive of a Dell notebook made in 1999 did not read the disk. We initially believed that the optical drive was aging. However, the actual cause of the failure was a BIOS error, which caused the optical drive to load incorrectly and not read the disk. After a simple adjustment, the optical drive worked normally. , and the repair order from the maintenance center stated that the optical drive was damaged and the optical drive must be replaced for a fee of 300 yuan. It is difficult for us to judge this kind of situation. When we get the repaired computer back, we can avoid many similar situations by asking a few questions.

3. Replacement accessories

Many well-known brands of laptop accessories are very expensive, and these so-called original accessories are also very popular in the market. For example, IBM's original memory modules, batteries, and adapters are much more expensive than those of other brands. During the repair process, these accessories can easily be replaced by repair personnel and sold. Similarly, it is best to use a digital camera to record before sending it for repair.

4. Attract repeat customers

I remember there was a joke that if a doctor could cure something in one visit, he would have to make the patient come 10 times before he could cure it. This kind of joke has become a reality in the field of maintenance. When repairing computers, some repair centers deliberately solve obvious problems and leave some problems that do not occur at the time, so that users will come back a few days later.

Summary:

There are still many shady secrets in the maintenance industry. For many consumers, they are often at the mercy of others. We have talked about many coping strategies above, but the actual situation will be more complicated. For laptop users, we need to know as much as possible about software and hardware. Generally, small problems can be dealt with by ourselves, and big problems can also be solved in our minds. With knowledge, the chance of being cheated will be greatly reduced.
