How to choose a tablet

Fashion on the tablets turned the IT industry in 2010 due to the appearance of the Apple iPad (everything that was before, a mass phenomenon can not be named), reached its peak in 2012-2013 and since then began to fade. Already in 2015 there was a clear feeling that all the tablets were tired — both producers and the public. And even the output of the iPad Pro could not turn the trend.

However, fashion is a fashion, and daily needs and tasks have not been canceled. During those few years, during which almost all families got tablets, users are accustomed to reading books, surfing the Internet, flipping social networks and mail (especially lying on a sofa or in bed) on such devices, watching videos and movies, playing some types of games … It is worth noting that the tablets were an ideal device for children: it was with them that most of those born at the end of the «zero» begin to get acquainted with the technique.

In general, whatever one may say, the tablet is a useful and pleasant piece. Maybe it is not as necessary as a smartphone, and not as universal as a laptop, but if you can get at least one tablet per family — it’s worth it. And consequently, the question of choice arises. Yes, and existing users of tablets sooner or later have to upgrade the device — either due to a breakdown of the old one, or because of its obsolescence (which, however, is slower than in the case of smartphones).

So, if you decide to buy a tablet, you need to answer the main question: why and where will you first use it (or is it already two questions? ..). The answer depends on two other fundamental questions: which operating system will the tablet and with which screen diagonal.

On the nuances of choosing between different OSes and diagonals of screens, you can write individual large articles, but we will not go into details here and try to highlight the main thing. With operating systems, it all depends on whether you plan to use the tablet as a full-featured replacement for a laptop, or not. That is, if you are going to travel with him on business trips, open and edit MS Office documents, run some professional programs such as Adobe Photoshop or 1C Accounting (at least occasionally), then it makes sense to purchase a tablet on Windows.

Choose a tablet
But if the tablet is supposed to be used for entertainment (games, especially children’s videos, reading books and magazines, social networks …), then in this case it is worth looking towards iOS / Android-devices.

As for the diagonal, the key point here is the place of use. For home use, especially if the tablet is purchased for children or the elderly, the optimal diagonal is about 10 inches. For a permanent carrying with you, it’s more convenient to use a smaller device (for example, if you get to work on the train or go for quite a long time on the metro, then it’s most convenient to read from a tablet with a screen diagonal of about 8 inches).

Well, the diagonals more than 11 inches are already designed for the rather narrow category of users who use the tablet for professional tasks, but they need a tablet, not a laptop. It can be artists, lecturers, etc. Finally, if you buy a tablet on the principle «let it be, but the application is there» and you can not decide in advance with the format of use, then take a device with a diagonal of about 10 inches, this is the most versatile option.

You can contact us for advice here.

Now, having defined the diagonal and the operating system, we can go directly to the choice. We decided to make the rubric on the diagonal, while taking out the tablets on Windows in a separate category, because there is a specificity, which is even more significant than, in fact, the diagonal.

Immediately warn that we did not include in the article products of little-known Chinese brands and their Russian «avatars», because for their reliability and durability they can not vouch, and, besides, their huge number, and they succeed each other swiftly, so if you really want to save money, choose at your own risk and risk, focusing on the characteristics and reviews.

Repair of tablets

The tablet computer massively entered our life — the usual thing to see it in the hands of even a schoolboy. The tablet is needed for different people for different purposes: for the businessman — for fresh news and information storage, for the courier — for reporting, for the child — for toys, for the housewife — for communication

… The list can continue for a long time — most importantly, the tablet was needed by everyone. A tablet with a broken screen is not needed by anyone. And if the tablet ceased to work — for some it turns into an almost personal tragedy — urgent and planned cases under the threat of failure. Thoughts that now it is necessary to look for a service center, carry a tablet for repairs, wait for repair and spend a certain amount for repairing a tablet — upset us and spoil our mood.

Tablet repair or another electronics repair in Cincinnati, in fact, consists of both simple:

— disassembly of the tablet
— dismantling of the repaired element (display, battery, chip, USB-connector, speaker, microphone, card-reader)
— element replacement (installation)

and complex factors:

— search for hidden faults (breakage of current paths, failure of electronic components,)
— dismounting the touchscreen from the screen unit
— micro-soldering under a microscope
Repair of Tablet PCs

In addition, the most difficult factor in repair — spare parts. The fact is that the production of plates in China is going on in two main directions:

mass production of tablets by large companies with a well-known name (Sony, Samsung, Asus, Lenovo, etc.)
local production of NO-Name tablets using BOM-technologies.
In the first case, the manufacturer’s concern for the brand dictates the production of a quality product according to the company’s internal standards and provides for the production with the manufacture of parts on specialized equipment that ensures the quality of the product at mass. In other words, all the details are made on special high-quality equipment in compliance with international standards.

In the second case, almost all parts, including chips (chips), are made on 3D printers in quantities of up to several thousand pieces. This technology is called BOM and provides for the production of any parts according to the customer’s schemes without observing the standards. In other words, you can order 2,000 chips for the manufacturer based on the documentation provided by you — it will make them, and how to use them is your own business.

NO-NAME tablets made using BOM technology are characterized by low price, low quality, limited circulation, lack of marking (or non-standard marking) on ​​the parts. And, consequently, the problem of finding parts for replacement and repair.

Service centers for repairing tablets solve problems with the search for spare parts only in part. If the manufacturer has applied parts of the tablet conforming to international standards, then your tablet will be repaired. Penall service center will order spare parts and repair your tablet. If the tablet uses the details of BOM-technologies — successful repairs are in question. But even in this case, the tablet can be repaired.

Problems and types of repair tablets:

Replacing the screen (touchscreen display assembly)
Replacing the Display
Replacing the touchscreen
Replacing (amplifying) the battery of the tablet
Replace the speaker (there is no sound in the tablet)
Microphone replacement
Repair at the elemental level (replacement of transistors, microcircuits, diodes, capacitors and other elements)
Replacing (repairing) the connectors of the tablet
USB connector
micro-USB connector
SIM card reader
SD (micro SD) on the memory card slot

 

Repair computer power supply

Today, there is a computer in almost every house. If the device breaks down, it becomes impossible to work, watch your favorite movies, listen to music, go online. At the first signs of malfunctions, contact the repair shop.

Power supply failure is a common problem. This part of the computer is subjected to the greatest load. According to statistics, a typical new power supply unit works without malfunctions for the first 3-4 years: after probable problems. Signals about the failure can serve: no response to the power button, any device shutdown, the smell of burning, uncharacteristic sounds during operation.

Main causes of power supply failure:

Over time, dust and dirt accumulate in the power supply, which is also the cause of the problems.
Ingestion of moisture, for example, if the unit contains flowerpots, which are regularly watered.
The wear and tear of the radioelements of the electrical circuit over time.
Power surges, overheating.
Failure of cords, plugs, power buttons.
Manufacturing defects.
The negligence of the host computer.

We recommend that you regularly clean the power supply unit and all its components. We also do repair computer Cincinnati. This will allow the device to work long and stably. Cleaning can be done for prevention. For work, please contact us. Before the repair is always carried out diagnostics. It helps to find out if the power supply is subject to repair or it needs to be replaced. If the item can be repaired, we will definitely do it. In case of need for replacement, we will offer the best components that are always available.

List of possible malfunctions
Let’s list the most common faults, typical for pulsed PSUs of system units:

fuses the mains fuse;
+ 5_SB (standby voltage) is absent, and also more or less than permissible;
the voltage at the output of the power supply unit (+12 V, +5 V, 3.3 V) does not correspond to the norm or is absent;
no signal P.G. (PW_OK);
The power supply unit does not switch on remotely;
The cooling fan does not rotate.
Verification procedure (instruction)
After the power supply is removed from the system unit and disassembled, first of all, it is necessary to perform an inspection for the detection of damaged elements (darkening, changing color, breach of integrity). Note that in most cases replacement of the burned part will not solve the problem, you will need to check the strapping.

If these are not found, proceed to the following algorithm of actions:

Check the fuse. Do not trust a visual inspection, but it is better to use a multimeter in the continuity mode. The reason for which the fuse has faded is the breakdown of the diode bridge, the key transistor, or the failure of the unit responsible for the standby mode;

Checking the disk thermistor. Its resistance should not exceed 10 Ohm, if it is faulty, it is not advisable to put a jumper instead. The pulse current generated during the charging of capacitors installed at the input can cause a breakdown of the diode bridge;

We test the diodes or the diode bridge at the output rectifier, there should not be a break and short circuit in them. If a fault is detected, the capacitors and key transistors installed at the input should be checked. The alternating voltage received by them as a result of breakdown of the bridge, with a high probability, brought these radio components out of order;

Checking the input capacitors of electrolytic type begins with inspection. The geometry of the body of these parts should not be disturbed. After that, the capacity is measured. Normal is considered, if it is not less than the claimed, and the difference between the two capacitors is within 5%. In addition, the varistors, which are sealed parallel to the input electrolytes, and leveling resistances should be tested;

Testing of key (power) transistors. Using a multimeter, we check the base-emitter transitions and the base-collector (the technique is the same as when checking the diodes).

If a faulty transistor is found, it is necessary to test all of its strapping, consisting of diodes, low-resistance resistors and electrolytic capacitors before soldering a new one. The latter is recommended to be replaced by new ones, which have a large capacity. A good result is the shunting of electrolytes with ceramic capacitors of 0.1 μF;

Checking the output diode assemblies (Schottky diodes) with a multimeter, as practice shows, the most common fault for them is short circuit;

Checking the output capacitors of the electrolytic type. As a rule, their malfunction can be detected by visual inspection. It manifests itself in the form of a change in the geometry of the shell of the radio components, as well as traces from the course of the electrolyte.

REPAIR OF MOTHERBOARD FEE COMPUTERS, NOTEBOOKS

Malfunctions of motherboards are difficult to classify due to the fact that a motherboard is a device carrying a lot of heterogeneous components interacting with each other and all devices of a computer system in various ways. Symptoms of breakages of motherboards are as diverse as the list of elements installed on it, but have some common features that we will try to list.

How are the MATERNITY BOARD MISTAKES?

Sudden reboots or «dead» hangs during startup or PC operation. Cyclic reboots or BSOD (blue death screens). May occur due to overheating of the components of the motherboard, and also due to a malfunction of the power circuits.
When the Power button is pressed, the fans start to rotate, but the computer does not turn on.

If you want to find where to fix electronics, you can visit our official website.

The problem may lie in the failure of chips, power circuits or a failure in the BIOS program.
When you turn on the PC button, it immediately turns off or does not turn on at all. The reason is most often a short circuit in the elements of the motherboard itself or in one of the devices connected to it.
At any significant load, the PC turns off, but there is no sign of overheating. Probably a defect in the processor supply circuits.
Do not work, or do not determine the devices connected to the motherboard.
Any functions of the motherboard components fall out: USB fails, there are problems with the graphics card, sound, network, etc.

WHAT DOES THE MOTHERBOARD DAMAGE?

No matter how trite, most often to various problems are the actions (or inaction) of the user. Most motherboards, whatever they say, are very reliable devices with a large margin of safety. In the event of a breakdown, our service center may be replaced by a laptop motherboard whose price can reach several thousand conventional units.

So, why do most PC motherboards break down?

Overheat. This is the most common reason for premature failure of any computer hardware devices, not just motherboards. The reasons for overheating are often the dustiness of the system unit from the inside or an ineffective cooling system.
Connecting faulty devices, which can cause a short circuit in the connectors and «pull along» half of the elements of the motherboard. Also, similar results can result in improper connection of devices.
Problems in the power supply system — jumps in the voltage in the network, poor-quality power supply and so on.

Manufacturing defects. If it is available, the motherboard fails or begins to malfunction soon after the start of operation.
«Direct» user handles. A number of settings of modern motherboards can be changed through software or in the BIOS. This can put the board into abnormal mode of operation, which will lead to its rapid deterioration.
In rare cases, the cause of the failure of the motherboard can serve as the action of the virus, if there has already been an infection of the computer — our service center will perform the treatment of computer viruses with a guarantee of the result and help establish the correct antivirus!

WHAT TO DO IF THE MOTHERBOARD FAILURE ARE SUSTAINED?

Since the motherboard is in contact with all the devices in the system, the first thing to do for diagnostics is to disable everything that is not required to start the computer. These are external peripherals and some internal nodes of the system unit. So you can exclude the impact of other equipment on the work of the motherboard.

If this method did not help to identify the problem, the second thing that a user can do is reset the BIOS settings to default by closing the Clear CMOS jumper on the motherboard or removing the CMOS battery (battery). This will eliminate some types of crashes in the BIOS program.

However, in this way only the simplest malfunctions that are not related to serious breakdowns are eliminated, which can only be diagnosed in a specially equipped service center. Our masters have extensive experience in repairing any motherboards and at any time are ready to repair computers in Kolomna in our service center. Make sure that you should not throw out the motherboard, when it can be completely restored and will serve you smoothly for many years.

The laptop is overheating: what should I do

The problem with overheating is one of the most common among laptop owners. The notebooks of all manufacturers are warming — from HP to Asus.

Symptoms of overheating — the laptop some time after power-up works fine, but then (if you run a heavy application or game) — starts either to strongly slow down (the processor power limiter turns on) or abruptly turns off.

In this case, before turning off, the fan of the notebook starts to buzz violently, and to the touch — the laptop becomes noticeably hot.

The cause of overheating is a violation of the heat removal system from the notebook case. In this article I will tell you in detail how the cooling system of laptops is arranged, what is the normal temperature, and what, in fact, if you can fry an egg on your laptop.

You can make diagnostics of the laptop in our center cincinnati electronics repair

How does the laptop cooling system work? Why is the laptop hot?
Notebook processor When the processor (the computer’s brain) does the work, heat is generated. Simply put — it is heated. The more difficult tasks fall on him, the more he gets warmer.

In order to somehow remove heat, a radiator is installed on the processor from heat-conducting material (copper, for example), and the place of contact is greased with thermal paste (so that there are no air gaps). To cool the radiator itself, a fan is installed, which blows the radiator plates, cooling them.

All the same can be said about the video card — their chips, when running modern games, heat up even more pohlesche than processors, and the cooling system is arranged in a similar way.

In the laptop, the space inside the case is limited, therefore, as a rule, all the heating elements are connected by one tube of a good conductive heat of metal. This tube on the end is welded to a grid of many thin plates, on which a small cooler blows, blowing hot air out of the housing.

For clarity, I drew a picture for you:

Laptop Cooling System

The problem is that, sooner or later, the space between the cooler and the radiator grill is clogged with a thick layer of dust, animal wool, tobacco tar (if you smoke behind a laptop). Here’s how it looks, in running cases:

Dust in the laptop

Naturally, a cooler can not blow through such a layer of felt. It turns out that hot air is chasing inside the case of the laptop, instead of leaving it, ensuring proper heat removal.

The temperature is steadily increasing, and if the thresholds are exceeded, the protection system is triggered and the laptop simply turns off, to avoid death from overheating.

On some laptops, instead of turning it off, a limit is imposed on the maximum processor power, this reduces the temperature, but the laptop starts to slow down considerably.

Also, one of the reasons for overheating the laptop is a dried thermal paste. But, nevertheless, basically, laptops are warming themselves because of an impassable layer of dust.

What is the temperature of the laptop is normal and how to «measure» it?
In general, different processors and video cards have different operating temperatures. But, nevertheless, an approximate framework can be outlined. In the idle state, the processor temperature of the notebook should be ~ 40-60 degrees, under load (launching the game, watching a movie), it can rise to 75-85 degrees Celsius.

It is important to know that temperatures above 90 degrees are critical. When it reaches ~ 100 degrees, the laptop usually turns off, «saving» itself from sudden death.

a test of the temperature of the video card. Naturally, we will not determine the temperature of the video card and the processor «by touch.» And with the help of an excellent program AIDA64.

What should I do if my notebook gets hot?
So, you measured the temperature of your laptop, and it turned out that under the load it warms up more than 90 degrees, and starts to slow down very much, or just turns off. What to do, you ask? And nothing — throw out and buy a new one. Joke. It’s not as bad as it seems, and your laptop can still be saved.

All you need to do is to carefully disassemble it, remove the motherboard, unscrew the cooling system, clean it from the dusty «plug» and replace the thermal paste. Then carefully collect everything, and again check the temperature with Aida.

If you do not have experience in disassembling laptops, but you have enough accuracy and straight hands, you can try to do it yourself. Different models of laptops are disassembled and cleaned in different ways.

Wherever it is necessary to unscrew everything to the last screw, that would get to the cooling system, and some laptops can be cleaned only by removing the bottom cover.
How much time does the cleaning of the laptop from dust with the replacement of thermal paste?
The first time a neat disassembly-cleaning-assembly can take you considerable time (3-4 hours). Having disassembled-assembling a dozen or so laptops, you will be managed for an hour, and without any instructions.

5 steps to save or repair a wet phone

What should I do if water gets into the cell phone?

Summer, the time of holidays and also how our life is unthinkable without a cell phone, also summer vacation is difficult to imagine without the sea, the beach, the pool or the bath in the end, shorter than the water.

Unfortunately, the pace of modern life is such that even on vacation we can not part with the phone. But the problem is that most of our little assistants are terribly afraid of water. Sometimes a few splashes or drops of rain or even just high humidity is enough to make the phone break and permanently cease to work. And despite the fact that getting liquid into the electronic device almost always does not pass without a trace, there is still a chance to save the phone if you make several correct steps to save it after water hit.

1. Remove the phone from the water and immediately remove the battery. The fact is that corrosion is not so terrible from water (there are not so many iron elements in the phone as a terrible electrocorrosion that flows under the influence of an electric current and accelerates corrosion processes hundreds or thousands of times.) There is no electricity, no reaction.

2. Do not try to turn it on or press any buttons at all! The fact is that as long as the keys are in the normal position, there is a possibility that the water has not passed through them, but as soon as you press, a gap is formed immediately and water is sucked in by the pump In the resulting gap between the button and the body.

3. Wipe and shake out all the water from the phone as far as you can. Use a towel, a dry T-shirt, paper napkins, etc. for this. Pre-remove the SIM card, memory card and open all the plugs that are there.

4. Contact the service center immediately through our website http://electronicsrepair.site/. The fact is that no matter how hard you try and how fast the battery is removed, it’s still water, most likely it got into the inside and an irreversible process of corrosion began. in the closed case of the phone, water can be stored for up to a week and all this time it will act on the conductive parts of the phone destroying them and closing the power parts of the phone. Even if the phone turns on and does not seem to work to the workers, do not be deceived and do not be deceived; inside it is the process of destroying your phone and if it is not stopped, it will most likely end in a breakdown that can not be fixed anymore. conductors and contacts will be corroded. Authorized service centers use special solutions that not only clean the phone, but also stop the process of corrosion, returning the phone to service.

5. If you are away from the village and the service center, you can try to use the old way, namely: try to drain the phone by immersing it in a bag of dry rice. Rice pulls well and absorbs moisture, so there is a possibility that all moisture from the phone and battery will be absorbed into the rice and this will slow down corrosion. In rice, you need to put not only the phone, but the battery, as well. it also contains an electronic circuit with microcircuits inside it and is even more subject to electrocorrosion since it is impossible to disconnect the circuit. Keep the phone in a package or a container of rice should be at least 2-3 days! The process of drying is slow and haste here will only hurt. Instead of rice, you can use silica gel, which is often put into shoes and other items when selling, it is better than rice absorbs moisture, but it is difficult to find it in sufficient quantities. Sugar, salt, etc. to use categorically it is impossible.

But even if you yourself decided to drain the cell phone and after waiting a few days to turn on the phone and it works, you still strongly recommend that you take the phone to a service center and do a prophylaxis, otherwise after a while the phone will not work. The point here is that, as a rule, the phone does not fall into distilled water, naturally this water has various impurities of salts, metal ions and so on. and all these trace elements settle very thinly on the board after the water dries, they are very hygroscopic (ie able to absorb water) and as soon as you get into higher humidity during use, these salts and microelements immediately absorb moisture from the air and begin the process of electrocorrosion and the destruction of contacts of your phone, this will happen until the phone is completely out of order and no one will help him further, because to restore such a phone will be very expensive (if at all possible).

In a professional service center, they must clean the phone by washing and washing away all salts, trace elements and other microparticles from the board, then treat it with a special solution to prevent and protect against corrosion, then dry it in a special chamber where a strictly set temperature and humidity completely eliminate damage to temperature-sensitive elements of the phone (display, camera, etc.) Of course, such special equipment is not cheap and it can not be afforded by every service center, that’s why we are Laga apply to large authorized service centers.

Remember one simple rule: the sooner you bring the phone to the service, the probability of its recovery is higher and the price for work is less, Do not test fate, statistics in this case have long said that the miser will pay not once. Take care of your time and money.

Typical Laptop Failures

Very often, the user experiences various breakdowns when using the laptop. Breakdowns can relate to the technical condition of the laptop or the problem of loading the operating system and software in general. We’ll look at the types of problems and how to fix them. Technical specialists basically distinguish three groups of faults in laptops: software, hardware and mixed. Of all, about 40 percent are software problems, otherwise it is a technical problem.

Laptop repair cincinnati

First, let’s look at software failures. Among such it is possible to distinguish such symptoms as: slow operation of the OS, the occurrence of errors, critical errors, suspending during actions, spontaneous reboots, slow loading of the operating system. The cause of such problems can be a general clutter of the system, errors in the system registry, congestion of partitions, system instability. In this problem, most often the user is to blame. In order to bring the work into normal mode it will take time, a couple of programs and skillful hands.

Cleaning the registry, full computer scan for malware, cleaning temporary files and debris, defragmenting disks, installing critical updates, all this will help speed up the work. For prevention, you need to install an antivirus program and constantly update the signature base for viruses, install recommended updates and monitor the status of free space on the system disk, do not run questionable programs. Well, if you still did not help or aggravate the situation (after cleaning the laptop of viruses, there is often a problem that the operating system stops loading), then you will definitely be helped by a full reinstallation of the operating system and its correct configuration at the initial stage, this procedure is long and boring, but 100% effective. You make shure by read post in our official twitter account.

Let’s move on to the problems at the hardware level. Here everything is an order of magnitude more complicated. This problem can be divided in turn into two subtypes: mechanical breakages and electronic breakdowns. Mechanical failures include: damage to the matrix (screen) of the laptop, damage to the case, mechanical damage to the optical drive (dvd-rw), fracture of various loops and wires, wear of curtains (loops), liquid spills, torn power connectors, USB. audio input, etc. All this can be caused by falling, unskilled interference or simply careless attitude towards your technique. But repair all this is not so easy and sometimes expensive and often for help contacting the service centers. Repair at home without special tools and skills will only lead to an aggravation of the problem.

To electronic breakdowns can be attributed such as:

the laptop does not turn on, there is no image on the screen, the laptop does not make noises, in this case there can be a lot of problems, starting with the battery / power connector not working and ending with the malfunction. bridge. For a detailed study of the problem you need to conduct a complete diagnosis of the laptop.

The notebook is noisy, the bulbs are blinking, there is no image on the screen, no physical damage to the matrix is ​​observed. The problem can be hidden in the faulty matrix loop, in the failure of the inverter or BGA video chip.

The laptop turns on, the black screen and no signs of OS boot. Often this is due to a problem with the BIOS firmware.

In general, problems with the laptop can arise very, very much, we did not cover such issues as the failure of the hard drive (hard disk), Wi-Fi adapters, touchpad (touchpad) and other many elements, just because for each problem you can to argue very long. Therefore, we are happy to help you in solving any issues concerning your laptop. Diagnosis on professional equipment, skilled craftsmen will help to find and solve any breakdowns. We are looking forward to see you in our Electronics Repair and Service Center: electronicsrepair.site — Low prices, warranty for all types of work, urgent repairs.

Why do computers break down?

Incorrect computer assembly.

The computer has never been turned on, but already broken? A common reason for contacting a computer service. Unskilful actions on assembling the computer lead to damages of contact tracks of the motherboard, processor, overflow of thermal grease and many other things. Trust computer assembly professionals need.

Children & Computers.

A big mistake parents make to allow their children to the computer. And not only because they can remove a program, but also it is very dangerous, since the computer is under electrical voltage. The burnt out computer because the child has flooded its liquid with a very common case.

Laptop’s mechanical damage.

What do you do when the computer freezes or starts to work slowly? Reboot or maybe bring it to the service of pc & laptops repair. More info on the our official website http://electronicsrepair.site/. There is a category of people who are not ready to put up with such a computer and begin to literally destroy it physically. Everyone saw this old movie when a man in the office is dissatisfied with his computer, and it breaks him in a frenzy.

Marriage of the manufacturer.

At the beginning of the article, we cited the fact that computers have become more perfect and, accordingly, the percentage of marriage has become significantly less. For serious computer components, the warranty, as a rule, is from 2 to 3 years. During this time, the computer becomes obsolete with the release of new, more powerful components, and accordingly if you want the computer to remain at the same or higher power level, then they need to be changed.

 

We recommend that you always save checks for purchased video cards, processors, etc. in order to return the defective part to the seller.

To summarize, we can say that the human factor is involved in most computer failures. If you want your computer to be always up and running quickly, then contact a service that does computer repair in Yekaterinburg for help.

I stopped booting the computer
If the computer starts when you press the Power button, but it does not load Windows, it is most likely a problem with the software, namely:

deleted the Windows system file.
installed an incompatible program.
«Caught» the virus on the Internet.
The complexity of this type of malfunction is easy and the problem is solved within 30-40 minutes.

The computer has stopped turning on
Causes of malfunction:

The failure of computer components (video card, RAM, processor, power supply, motherboard).
The failure of the connecting wires.
The failure of controllers, resistors, etc.
The complexity of this type of failure is determined only after the computer has been diagnosed by the master. The cost of computer repair in Yekaterinburg depends on the complexity.

Monitor does not work
Reasons for a computer monitor malfunction:

The monitor does not turn on, the power indicator is off
The power indicator is blinking, there is no picture
The power indicator is on — there is no picture, the backlight is working.
The backlight of the monitor does not light up or goes out after a few minutes of operation
Reducing the brightness of the screen and the appearance of a reddish tint
Stripes on the screen
Distortion of image or color rendering
The monitor does not display the image from the computer, it displays messages
Simple check:

Disconnect all wires from the monitor
Connect only the power cable
The monitor should turn on. «No signal» appears on the screen
After a while, the monitor goes into power saving mode (the power indicator changes color, the picture disappears)
In this case, the monitor is likely to be working properly. Of course, there are exceptions.

You can also check the health of the monitor by connecting it to another computer.

If the monitor is not working, you should contact our service for diagnosis and repair.

Keyboard and mouse does not work
The most common reasons are:

remove drivers.
Bay of liquid.
The keyboard «does not obey», behaves unpredictably.
The mouse pointer does not work when you start Windows.
Mouse badly obeys when we move the mouse.
The simplest solution is, of course, a replacement for a new keyboard and mouse. If you bought new components, but they also do not work, then you need to carry out diagnostics. Either customize Windows, but it depends on the cause of the failure.

Filling the computer with liquid
The first steps after the computer is flooded:

Shut down the computer from the network.
Wipe with a soft cloth visible traces of liquid.
Do not try to dry the computer and leave it off for a couple of days.
Urgently call the computer service and report your problem.
When the bay is liquid, the chips suffer from computers that start to oxidize. If you leave to dry the computer, then the situation will only worsen and we are unlikely to be able to help you.

When you work, the computer makes strange noises
The main reasons for this phenomenon:

Dustiness of the computer, i.e. accumulated layer of dust, prevents the normal operation of the fans.
The failure of the «paw» of the hard drive that moves, inside by reading data from the magnetic disk.
Damage to fans that perform cooling.
In any case, you need to diagnose your computer.

Slow running computer
Main reasons:

The software load on the computer does not match its characteristics. Try to remove programs that create a lot of work.
A large number of viruses.
Dustiness of the computer’s system unit.

How to choose a service center for the repair of laptops?

Repair of laptops

In Minsk, there are more than a hundred service centers that offer services for the maintenance of computers, laptops and other equipment. And private masters even more. Of course, such an impressive choice has both advantages and disadvantages. After all, not in every service center you will get high quality services, solution of the problem in a short time (for example — how to fix a computer that wont turn on), adequate pricing and guarantee.

Situations when people are frankly «bred» for money, performing poor-quality repairs, or offering inflated prices for parts and services, are quite common. As a result of such «computer help» you lose time, money, and most importantly — valuable information.

How not to be disappointed, faced with scammers and non-professionals? How quickly to determine that before you — a conscientious company in which people work, who want to not only earn, but also help you solve problems? Simple and effective advice will help in this matter:

Tips for choosing a service center

Well-written contract. Service center
In the contract for the provision of services for the repair or maintenance of computer equipment, all the terms of cooperation between the contractor and the client must be clearly spelled out. You should understand that when you contact a service center, the material responsibility for your equipment is assigned to its specialists, so that in case of poor repair, you have the opportunity to demand compensation.

Data protection.
The service center, which takes care of its reputation, will do its utmost to preserve your personal data and will in advance discuss this matter with you. And scammers either remove them or use them for their own purposes, which will cause irreparable harm to you and your company.

The price of the issue.
Many unscrupulous companies attract customers with advertising and profitable shares. For example, you promise to quickly perform a complicated laptop repair for only 100 rubles. But in practice it turns out that the cost of work is 2-3 times higher. Therefore, before signing the contract, specify all the details — the list and duration of work, the cost of spare parts and the repair itself.

Guarantee.
It is difficult to imagine a good service center, in which you will not be given a guarantee. But fraudsters are still there, so it is important to remember that the existence of the guarantee allows you to legally contact the company to carry out repairs to make a diagnosis technique again and fix the problem free of charge or receive compensation.
