Возможные неисправности ноутбуков и методы их диагностики

Для многих людей ноутбуки – это незаменимое средство работы, развлечения и общения. Они прочно заняли место в жизни людей. Свобода передвижения и мобильность с ноутбуком – это гигантское преимущество по сравнению с настольным компьютером. С ним можно путешествовать по миру, или по своей стране, или передвигаться по городу. Все это, а также возможность автономной работы делает ноутбук просто незаменимым. У вас всегда под рукой любимые фильмы, развлечения, полезные приложения и музыка.

Конечно, ноутбуки тоже подвержены кризисам, и порой «заболевают», в принципе как и человек. Болезни возникают в зависимости от особенностей эксплуатации, воздействия окружающей среды, а также возможны заводские браки. Поэтому своевременная диагностика нотубука необходима (по аналогии с человеком, которому нужны периодические плановые обследования организма). Диагностика позволяет быстро отыскать проблемы или неисправности и устранить их вовремя, пока они критично не ухудшили работу ноутбука.

Если вам требуется диагностика или ремонт ноутбуков в Могилеве, то важная задача – это правильно выбрать ремонтную мастерскую. Этой задачей не стоит пренебрегать. Главное, что нужно сделать в первую очередь, это узнать, на каких марках ноутбуков специализируется мастерская или сервисный центр. А то довольно часто бывает, что компания занимается ремонтом только определенных марок, или вообще одного производителя. И в этом случае, если предварительно не позвонить, и не уточнить детали, то можно съездить зря, и впустую потратить 2-4 часа. Особенно в крупном городе.

Также обязательно нужно выяснить, какова квалификация персонала и опыт работы сотрудников. Возможно, что молодая компания с амбициями работает на 5+, но бывает, что более опытные компании, «старички» могут выполнить ремонт и обслуживание гораздо качественнее и быстрее. Хотя, конечно, это очень спорный момент.

Со стороны, возможно кажется, что работы по диагностике ноутбука очень простые. Но это только на первый взгляд. На самом деле работа требует большого опыта, знания всех комплектующих ноутбука, повышенной концентрации внимания и усидчивости. К тому же необходимо наличие специального инструмента и аппаратуры. Так что качественную диагностику можно произвести только в мастерской, но никак не в домашних условиях. Порой бывает так, что саму неисправность найти труднее, чем потом ее устранить.

Также, при выборе сервисного центра нужно помнить, что он отвечает за сохранение всех данных на ноутбуке. В том случае, если работают дилетанты, то у вас не будет уверенности, что ваши данные не будут утрачены. Помимо этого, сотрудники могут просто обмануть, выдав небольшую проблему за истинную причину неисправности.

Например, если требуется лишь пайка разъема или контактов, вам могут сообщить, что нужно полностью менять комплектный узел. Цена за ремонт в таком случае будет завышена в разы!

Frequent cell phone malfunctions

The most frequent malfunctions of the cell phones and how to eliminate them through DIY.

1. Software is cluttered or lost – in this case even a master with extensive experience can not always immediately determine the breakdown in the phone, namely, what exactly is the fault – in or on the iron.

electronics repair shop

If you are not exactly sure what your fault is, try, first, to fix it as a software error.

For different manufacturers of cell phones, as well as their models, there are various ways to cure a software failure: try to make a general reset of the software, or replace it and format it.

Beforehand, read the instructions of the phone, it should indicate how you can reset the firmware of the phone or completely restart the software, back to the factory settings.

Be careful and make a backup copy of the data, to avoid losing it, if something goes wrong after resetting the software.

Also, make sure that during the software update, its reinstallation or formatting the phone data, there are no failures or interruptions in the cable connection, power supply, otherwise it can lead to even more problems with the phone.

If none of the above methods helped you, then most likely, the problem in the phone is connected with hardware, or hardware, if to be more precise.

In this case, you can disassemble the phone, conduct a visual inspection and clean it from dust and dirt inside the case. Or just better to take it to the electronics repair shop.

2. If you do not hear the caller, or the sound disappeared altogether, then first you need to clean the speaker from dust. Over time, the speaker is clogged with dust and this is a frequent cause of hearing loss.

Performing this operation, you need to be very careful, and do not damage the thin mesh, which protects the speaker from damage. Clean gently and without using sharp tools.

3. Your interlocutor does not hear you. The reason for this is most likely a dirty microphone, which must also be cleaned. If this does not help, then probably the microphone is out of order, then you need to contact the service center for repair.

4. If the phone does not want to be charged, or it often turns itself off, and there are problems with turning on, the main reasons in this case can be either a battery, or a charger, and a connector for connecting the charger. Independently here you can make a replacement battery, charger or clean the phone’s charging connector and its contacts.

Поломка экрана смартфона

замена экрана смартфона

Экран смартфона – насколько он надежен и по каким причинам он ломается чаще всего?

Размеры смартфонов становятся все больше, и подавляющее большинство их выпускается как правило, с экраном 5-6 дюймов. При этом компании, занимающиеся выпуском смартфонов клятвенно заверяют своих покупателей, что стекла экранов имеют закалку, усилены и переносят удары и другие механические повреждения.

Правда, в реальной жизни, происходит все с точностью да наоборот – именно дисплей оказывается одним из самых хрупких и слабых элементов смартфона. В какую стоимость обойдется замена экрана смартфона того или иного производителя зависит от наличия и объема запасных частей на рынке электроники. Например найти экран для Samsung не составит труда и работы по его замене обойдутся для владельца телефона по разумной цене. Однако, некоторые производители устанавливают цену на новый дисплей, доходящую порой до 50% стоимости нового аппарата. В таких случаях целесообразность ремонта смартфона оказывается под вопросом.

По каким же причинам экраны смартфонов наиболее часто выходят из строя?

Порой бывает так, что через 6-8 месяцев пользования телефоном, владельцы могут обратить внимание на то, что экран мерцает, обычно это происходит в режиме минимальной подсветки. Такой эффект обычно происходит по причине нестабильной работы аккумуляторной батареи. Самая распространенная причина такой работы – это то, что смартфон заряжался сторонним зарядным устройством. Обычно владельцы не обращают внимания на рекомендации производителей телефона – «заряжать только блоком питания, рекомендуемым заводом-изготовителем телефона». Из-за того, что пользователи игнорируют этот совет, и начинают заряжать свои смартфоны чем попало, батарея постепенно выходит из строя. Т.к. у каждой модели телефона существуют индивидуальные требования к зарядному току и уровню напряжения при зарядке. И эти показатели для различных блоков питания могут сильно отличаться.

Дальше самая распространенная причина выхода экрана из строя – это падение смартфона в воду или иное попадание внутрь него влаги. Если корпус не имеет усиленной защиты от влаги (например класс IP67), то вода проникает внутрь и начинает пагубно воздействовать на металлические элементы микросхем – окислять их и коррозировать.

Если влага попадает на дорожку шлейфа сенсора, то это может стать причиной того, что экран не будет реагировать на касания и нажатия, а также беспорядочно открывать различные разделы и меню телефона.

Restore the Windows (part 2)

Damage to the registry

One of the reasons that requires the recovery of Windows is registry corruption. This happens infrequently. Sometimes the computer user can mistakenly corrupt the registry.

The Windows Registry or the Windows Registry is a hierarchically constructed database of settings and settings on most Microsoft Windows operating systems.

The registry contains information and settings for hardware, software, user profiles, presets. Most of the changes in the Control Panel, file associations, system policies, the list of installed software are fixed in the registry.

After you install Windows on a disk, the following files are stored in the% SystemRoot% \ System32 \ Config \ directory (for example, C: \ Windows \ System32 \ Config \):
system
software
sam
security
default

(All files (file names) without extensions: A copy of these files is stored in the C: \ Windows \ Repair \ directory)

In addition, the files used to build a “working version” of the registry can be stored in directories:
% SystemDrive% \ Documents and Settings \ <Username> \ – the file “Ntuser.dat”
% SystemDrive% \ Documents and Settings \ <Username> \ Local Settings \ Application Data \ Microsoft \ Windows \ – the file “UsrClass.dat”

It is obvious that as the user works, mistakes are accumulated in the registry, including for the reasons listed above. In this regard, the registry is prone to damage from both programs and viruses.

In order to avoid this, it is necessary to regularly check the disk for errors, viruses; checking the registry for errors and defragmenting it.

To edit the registry manually, the system utility regedit.exe is used.

Reasons for rebooting the computer
The reasons listed above usually lead either to the computer crashing, rebooting (with some Trojans and viruses) or to being unable to work properly.

The same symptoms can also be caused by hardware malfunctions – overheating, bad sectors on the hard disk, and “glitches” of RAM, but we’ll talk about this in a separate article.

OK, if you need to restore Windows or fix some other troubles, go to the google and type: electronic repair service near me.

Then you can find us on the first google’s page and call us right now!

Restoring the Windows

Most software problems are caused by corrupted system files or Windows settings, due to viruses, and if the registry is damaged.

Consider the causes of these injuries.

Damage to system files
The fact is that most programs use standard Windows system libraries (files with the extension * .dll) for go, to reduce the amount of the actual program. If these libraries are damaged, the installed programs can not work correctly.

Sometimes there are situations when with frequent installation and removal of programs, some system files (* .sys) and libraries can also be uninstalled with them. This can happen when the program overwrites (overwrites) the original system file by installing it on its own.

In order to avoid this, it is necessary to install as few programs as possible and experiment on the working system by installing and removing programs.

There are also cases when, when several programs or processes run, a collision occurs – an attempt to simultaneously access several programs or processes to the same resource (file). This situation is called a deadlock or mutual interlocks.

Deadlock is a situation in a multi-tasking environment or a DBMS, in which several processes are in a state of infinite waiting for resources captured by these processes themselves. Often such situations lead to the hang of programs.

I want to note that hangs also occur when the kernel of the operating system tries to switch from one process to another, but for some reason can not (for example, the started process hinders it). Visit our website and let me remind you that in multitasking operating systems, all processes are performed in turn – the processor once every 25-100 ms switches from one task to another. At the same time, processes can not be performed. In this situation, it is recommended that you wait a few minutes before the automatic unlock. If this does not help – try to “kill” the process via Ctrl + Alt + Del.

Windows settings due to viruses failed
Most of the time, configuration failures result from the penetration of viruses or Trojans into the system. Those are started as programs in startup or as services that can not be seen, but they prevent the change of Windows ntraznek.

Symptoms of infection with viruses and trojans are the following indirect signs:

strange windows appear after which the computer turns off or reboots
there’s no way to change Windows settings
there is no possibility to remove / install programs
there is no way to view hidden files and folders
you change the system settings, and they are not saved
New items appeared in the right-click menu of the mouse
folders do not open as before
periodically Windows tries to connect to the Internet or open there any site

The main sources of viruses are the Internet (namely, dangerous sites with free software, music, movies, pictures, entertainment sites), local networks (mostly large type Matrix), flash drives.

The recommendations are simple: to use anti-virus protection, firewalls, antitrays.

There are a lot of ways to clean and restore the system: use the “System Restore” utility (rollback), Recovery Console, in especially severe cases – use Windows Live CD and special utilities to clean the system.

Technology repair Seagate hard drives

It’s been more than a year since Seagate’s new line of Seagate Barracuda 7200.11 disks appeared in one of the leaders in the production of hard disks – Seagate.

These disks have a density of 250 and 320 gigabytes per plate and a spindle rotation speed of 7200 rpm. In addition, they have a fundamentally new design of the control firmware. All Seagate drives of the older series were based on the principles developed by the engineers of Conner Peripherals, which Seagate acquired in 1995. As for the drives from the new line of Seagate, they represent a blending of these old principles with the SCSI architecture.

It is because of this in the new family of drives there are no models with a PATA interface, and there are only models with a SATA and SAS interface. Unfortunately, the first “pancake” turned out to be “lumpy” – the new family inherited both a number of old flaws in the Konner models, and a number of new specific “sores”.

One of these “sores” manifests itself very often and consists in damage to the official disk information. It manifests itself in two very similar ways: the disk either is not detected in the BIOS of the computer at all, or is determined, but as a drive with zero volume.

The disks that have caused this malfunction began to arrive in the guarantee departments of the vendor companies and were successfully replaced under the warranty for new ones. But, unfortunately, the user lost his data stored on the “lost” disk.

Therefore, we consider here the methods of electronic service, data recovery, applicable at home, with typical faults that occur in the discs of a new family.

As the study showed, the disks either damage the part of the translation table that is responsible for the G-List, in which case the disk is determined by the volume 0, or the contents of the S.M.A.R.T table corrupt.

In the first case, to restore the disk and gain access to the information on it, it is necessary to restore the translation table by recounting it from the defect sheets. However, when recalculating, it is important that defects from the G-List are not transferred to the P-List. (The specifics of the device defect sheets and hard disk drive systems are discussed in our previous articles).

How to do it? Although the disk family is new, it inherited something from the old Konner family. This “something” is the control interface RS-232. To restore the service information, we will use it.

How to avoid scammers while repairing your computer?

The computer (and all its devices) is entered in the register of special products as a complex technical device. Of course, this register primarily deals with the relationship of sellers and buyers, but this relationship extends to people who are professionally engaged in the repair of personal computers.

Unfortunately, the world has not yet invented non-breaking things, so sooner or later any computer owner will have to face the problem of a broken PC. There are two main groups of faults in the computer: software and hardware.

Trouble with the software, as a rule, is solved quite quickly and easily: it is enough to call a specialist, and he will solve the problem in just one or two hours. There is nothing complicated in this, but even here you can face scammers.

How to fix laptop and not be deceived by scammers. How do they work?

First, you may be required to pay for the restoration of the required files. In principle, this is normal, but it is necessary to know that the data is flown from the C drive, and if they are located on other, additional disks, then they will remain there, and you will pay for the work that you did not do and did not have to do.

Secondly, specialists, using ignorance of the townsfolk, often wind up prices, exaggerate the amount of necessary work and thus profit. Thirdly, a very common type of fraud is the installation of pirated copies under the guise of licensed programs and taking money for them in full. Therefore, try to check all the programs that are installed on your computer.

Well, fourthly, scammers can say that the problem is not in the software, but in the equipment, since the repair of equipment is much more expensive thing (especially with the replacement of damaged parts). In this case, ask for repairs in your presence.

How can you tell a fraudster from a specialist? Here you can advise to do two things:
1) when calling, ask about the presence of a certificate – the specialist must respond immediately, and the fraudster hesitates;
2) look at the newspapers over the past year – if there is an advertisement of this person in them, then he is probably a specialist (scammers, as a rule, work simultaneously).

Try to learn how to independently identify problems with software from hardware problems. With some experience this will allow you to save a lot of time and nerves.

Now let’s talk a little about repairing the equipment. In this case, calling the master at home is not the best option. It will only be useful as a diagnostic tool to determine that the problem is not in the software. It is best to contact a company specializing in computer repair. However, there are some subtleties here, and you can face fraud.

Therefore, before you give your system unit, rewrite the numbers of all the components, and after the replacements made (if they were, of course), be sure to require the old parts back. Otherwise, under your fictitious pretext, you can completely replace the workpiece and take money from you for it. Remember, there is no excess reinsurance!

How to open an electronics repair business: computers, laptops, cell phones

Article for those who want to open their electronics business, to earn money on repairing phones, laptops, tablets and computers. Practical advice from the business owner watch on this official website.

Hello, my name is John, I’m the founder of a network of service centers for the repair of telephones, laptops, photo and video equipment.

I have a video on youtube channel about how to open my service center, where I tell you what you will need directly to open.

But before you start to open your first workshop or service center, it’s worth doing some preparatory work, without which your grand opening slowly goes into a sad closing and calculation of losses.

The first thing to begin with is to clearly prioritize. Understand what is most important in this business, and what is secondary. Without which knowledge and skills you can not build a profitable business, and without which knowledge you can do at all.

What do you think is the most important thing in the electronics business?

– Skills and experience in repairing modern technology? – No

-Access to suppliers of original spare parts and the lowest prices for parts? – No

– Own premises and start-up capital? -Also no.

The most important thing in this business and in any other is the skills of attracting customers: lidogeneratsiya, marketing, as it is now just not called. If you do not have customers, then everything else does not matter.

Someone will object: “Well, if my company does not perform repairs properly, we will have high prices, poor quality of spare parts, so, accordingly, customers will not come to us either.”

Yes, all this is certainly important, but not primarily, what will your service level mean if you can not create a flow of customers, who will evaluate it? 1-2 customers a day and even then, even such a number of orders for many new open repair shops for phones and laptops is in practice unattainable.

These guys are many, open, work a month or two in the minus and close.

To what I tell all this, before you start your business, you should definitely get training in the course of web marketing, business analytics, get at least basic knowledge in contextual advertising, SEO, get acquainted with all existing channels of attracting customers.

Such knowledge you can get both independently from free sources on the Internet, and to pass paid training, thank God now educational programs on this subject are missing.

So, the first and most important thing is to acquire knowledge in web marketing, to become a good specialist yourself.

In second place in importance, obtaining practical knowledge and experience in the operating activities of the sphere in which you want to open a business.

If you did not work in a similar service center, for example, you worked at a printer repair center, but you want to open a repair shop for laptops and phones. Then I strongly recommend that you first get a job on the right profile, work at least six months.

Because everywhere there are many nuances, so-called, reefs, which you should know.

And the last tip: in parallel with the training, start developing the site, in advance, think out the design, structure, correspondence to the simantic core of the pages of your future resource. Choose a good old trust domain, choose the right engine and a lot of other nuances about which you will learn at school and in parallel will begin to apply in practice.

As a result, you will have to install a program for keeping records in the workshop (I recommend the Gincore program), find a good room, buy equipment, furniture and sign.

This is how the founder of a successful service center should spend six months before opening it: the day at work in the service, in the evening at the courses on web marketing, at the weekend – creating website.

Computer Lags: How to fix the problem?

Agree, it’s not very pleasant when a computer lags and nothing can be done on it. And to find out the reason at times is not so easy, because there can be a lot of them. But in this article we will analyze all the main reasons and try to eliminate logs from the computer.

Tips for removing lags from your computer (read more here: electronicsrepair.site).

So what do you need to do in order not to lag the computer? Carefully read the tips listed below. Perhaps to eliminate lags you need to use several of the listed tips, because using one is unlikely to help.

▶ Check your computer for viruses.

What’s the first thing that comes to mind when the computer starts to lag? Of course, this is the presence of all kinds of viruses, trojans, worms, so first of all you need to check your computer for malware. You can use one-time scanners, the best is Dr.Web CureIt, the link above will find where to download and how to use this antivirus scanner. Viruses are the main cause of computer lags, so I do not advise you to miss this point, but to use it first.

▶ Clean the system of debris.

If it turned out that the computer is not infected with viruses (you scanned the system before, of course), then the next reason for computer lags can be unnecessary files and any garbage in the system. Programs cleaners there is not enough, but perhaps best of all with this problem cope CCleaner.

▶ Remove unnecessary programs.

Are there many programs that you do not use? Remove them. Article, how to properly remove unnecessary programs, you will help. Remove without regretting any Yandex.Bar and Satellites@Mail.Ru, which are sometimes secretly installed when installing other programs.

▶ Clean the registry.

After cleaning the garbage, it is also necessary to clean the OS registry. After any manipulation in the system, the registry leaves all unnecessary branches, which can cause lags of the computer. To do this, you need to clean the registry, as described in the article on the link above. Warning: before editing the registry, it is recommended that you create a backup copy of it so that you can quickly restore everything from backup.

▶ Defragment the HDD.

You can read about the defragmentation of hard disk in this article, everything is described here, what it is and how to use it. If you do not do defragmentation for a long time, then the hard disk lags may appear. I just want to say that this can prolong the life of the hard drive, not the SSD, namely the hard drive (HDD), although the logs may not be so serious, this can lead to a low speed of writing / reading the hard drive.

▶ Remove programs from startup.

When you turn on the computer, many programs and utilities are automatically loaded with the operating system. It is recommended that you uninstall programs from startup that prevent the system from booting normally.

By default, in Windows, you can remove programs from startup as follows:

1. Start the context menu “Run” (Start-Run), or by using the Windows key combination “Win + R”.
2. In the dialog box enter the msconfig command, click on the OK button.
3. In the window that opens, go to the “Startup” tab.

Now only it is required to remove the tick from those programs that should not be run with Windows.

Unfortunately, this way you can not remove all programs. The easiest way to do this is with CCleaner, which gives you access to a complete list of installed programs on your computer.

▶ Disable unnecessary Windows services.

Like programs, Windows services can cause lags when they are launched a lot. Therefore, you need to disable unnecessary services.

Disable superfluous services it is possible as well as to remove programs from autoloading, only it will be necessary to pass to a tab “Services”. Now, in the same way as in the paragraph above, disable unnecessary services in vain downloading the system.

▶ Check the hard disk for errors.

The cause of the lag may be a malfunction of the computer’s hard drive. For this, it is necessary to check the HDD for errors by the utility CHKDSK, which is installed by default on the Windows operating system. Of course, you can use third-party utilities, such as MHDD or a powerful Victoria program.

▶ Clean the computer of dust.

Dust is very dangerous for computer equipment. And lag computer can because of dust, first you need to measure the temperature of the computer components – as described in this article (there you can find the optimal temperature of each component). Further, if overheating of a component is noticed, measures need to be taken. In this case, if there is overheating, you will have to clean the computer of dust, as described in this article, but here is an example of a laptop there, but I do not think there will be any problems with the system unit either. That’s all.

Evolution of a personal computer

How can I live without computers, smartphones and other gadgets today? Even more difficult to realize is that 50 years ago, these technologies could only be learned from science fiction books.

The first computers were created after the end of World War II. They were very large and expensive (they cost even more than the latest version of the modern MacBook). Therefore, only such employees of serious organizations, banks or leading universities could play such toys. But the development of home PCs (personal computers) was in the second half of the twentieth century. The first one is a PDP-8 mini-computer. It was released in March 1965, it was done by the corporation Digital Equipment Corporation.

It should be noted that when we call the PDP-8 a mini-computer, we mean that it did not occupy the entire room. PDP-8 was no more than a regular refrigerator, which for our time sounds pretty wild. Its price was $ 18500, but this did not prevent computer enthusiasts from buying this miracle of technology. Therefore PDP-8 became not only the first home PC, but also the first commercially successful computer.

Altair 8800
The next “breakthrough” was made by the company MITS, when in 1975 it released the computer Altair 8800. It is considered one of the “revolutionaries” of home PCs, as well as the first step in the formation of companies manufacturing personal computers.

What is the secret of Altair 8800? It was compact, productive and inexpensive. For only $ 439 each person could purchase parts for the computer and collect it using the magazine Popular Electronics. For 621 $ it was possible to receive already ready model. Altair 8800 had an Intel 8080 microprocessor with a clock speed of 2 MHz, and also processed 8 and 16-bit numbers. By the way, Bill Gates started his career precisely thanks to Altair 8800!

Apple II
At the same time, two more computer enthusiasts – Steve Jobs and Steve Wozniak – decided to create a company that would develop computer technology. Their truly revolutionary project can be called Apple II, which appeared in 1977. Jobs and Wozniak demonstrated how a general-purpose computer should be. Since that time, technicians could be used not only by enthusiasts or amateurs, but also by ordinary citizens.

IBM PC 5150
In 1981, IBM joined the mass excitement and released IBM PC 5150, which probably still can be found in some government agencies.

Commodore 64
The computer is considered one of the most successful home PCs in the world. In total, 20 million devices were sold. The PC was equipped with a MOS 6510 processor. It could also be connected to a TV and used as a game console.

Apple Macintosh
The next successful product of Apple was Macintosh, which finally determined the type of personal computer. The main innovations that the product sported were a mouse and a completely graphical interface. In fact, this is the great-grandfather of all modern iMacs and MacBooks. And this is the first computer that greeted its future users.

IBM PC Convertible
IBM PC Convertible is the first laptop in the world, which was introduced by IBM in 1986. It had an Intel 80S88 processor and 256 KB of RAM, which could be expanded to 512 KB. Also the laptop could boast of two disk drives and a modem. The PC was sold very poorly. It was heavy, not fast enough, and it was not easy to read from a liquid crystal monitor. IBM PC Convertible still remains the first laptop that was released in mass production and influenced the further development of the industry.

A little bit about the future
Technologies do not cease to develop. Now most companies are trying to create high-performance computers that would not take up much space. Leading is Apple, whose products over the past decade has gained immense popularity in all corners of the Earth.

Large personal computers are beginning to give way to ultra-thin laptops and tablets (although there are still enthusiasts who independently assemble and upgrade their PCs). According to forecasts of specialists, in 100 years the functions of a laptop or PC will be performed by smart watches, smartphones and holographphones, and powerful computers will be used to calculate large amounts of information.
