Chi does not start up the computer that works. The system unit does not fit: instructions for the solution of the problem. Zbіy pіd hour zavantazhennya operating system

To finish with an extended problem - the reaction of pressing the button on the computer. So if you are prompted to turn on the computer by pressing the button, nothing happens. My article will be described possible reasons such computer behavior.

Cause

So let's do it. Axis list of possible causes:

1. Vіdsutnіst naprugi in the electrical outlet;
2. Poshkodzhennya or non-contact to the wire that goes from the socket to the computer's living unit;
3. The button for raising the block of life is located at the closed station;
4. Breakage of the button itself of the computer's activation or її darts;
5. Departure from the harmony of the block of life;
6. Departure from the harmony of the mother's pay.

First of all, why should you start diagnosing a malfunction, why not change it, there is a voltage in the electrical outlet. Neobov'yazkovo cerobity tester. It is enough to include in it any other electrical appliance and switch to the one that works.

They gave a need to reconsider the number of inclusions of the black wire of life into the electrical outlet and into the block of life, as well as to make a good look at the subject of damage and fractures, especially from the ends of both roses. To get it out of the computer block, insert it back.

Let's step on the rock following the respect for the computer's life block. For whom to look at the back of the system unit in those places where the life cable comes from the socket.

If there is a button - vmikach, then there can be a smartened up.

Upvote button on animation block

The next thing you need to try is to start the computer without the power button.

Vymikaёmo computer and znіmaєmo bіchnu lid of the system unit. We gave a block of contacts, where the button is connected, the button is turned on, reset, the indicator is turned on and the robot hard drive. Call out to be found at the lower right kutka pay.

Raztashuvannya blocks of contacts on maternity pay computer up buttons

If you know її, we know all the contacts from it. For whom it is difficult to pull them uphill, writing down in advance or photographing them.

Now we take a twist, lower or another similar metal object and make contacts close, like signatures like “PWR_BTN” or “WP + WP-” or “PWR SW” just get to them with a twist one hour.

How to turn on a computer without a button to turn on - lock the contacts with a twist

If you can’t know the contacts behind the messages under them, otherwise you have the messages under them just every day, try to turn all the main contacts on the phone.

If the computer does not turn on, then the problem is not in the life button.

Now, if you want to revise the life block, you need to try installing a familiar worker, posit it with friends, or you know, or revise your block on another computer.

If the block of life is full, then the only reason that it is lost, if the motherboard is not working, if it happens to be minus, if only the capacitors are not corny on it, you can replace it.

The axis looks like capacitors that are puffed up on the motherboard.

The unreasonable nature of quiet computer problems often leads to pardons in diagnostics, without any impossibly qualified repairs. І approach to search for problems following from її exact description. The incompatibility, as described by the words: "when pressed on the button of life (power), the computer does not turn on, but the fans work," they call it a day or a pardon of initialization. Do not stray from the "non-inclusion" - completely idleness on the onslaught of power, the shards of the cause of these two problems sound different.

initialization, to this particular type- Tse readiness to possess to work. And just like one of the outbuildings, critically important for starting a PC, to start up, we can predict a typical picture:

• after turning on the system unit, there is a very loud fan noise (the stench wraps up on a constant high wind speed);
• they fired and did not go out the indicators of the keyboard and turned on;
• the screen becomes black.

There is nothing more to say.

Cause

Behind the statistics, most of the time, there are such problems:

• BIOS support - programs that are stored in the CMOS flash memory chips on the motherboard, which are responsible for the PC's start-up, as well as for re-verification of the operation of all devices at the start-up stage;
• the processor, which is in harmony, or the inadequacy of the living system;
• RAM failure ( operational memory) or the inconsistency of the installed RAM strips among themselves;
• failure of system logic microcircuits (chipset) on the motherboard, especially often on the piping bridge.

For other reasons, which can give a similar “clinic”, it is possible to note the failure of the elements in the mother board, which lead to destabilization of the life of the outbuildings, a defect in the soldered contacts of the microcircuits, the battery Owned, installed on a PC. However, it’s easier to catch on.

It is also important to understand that this problem is in no way the result of software failures in the operating system. Bo її zavantazhennya navit not pochinaєtsya.

Diagnostics

What can a koristuvach grow up, leaning against such a situation? If you don’t want a special possession, you can try to solve the problem in your home minds. Finish it off with a twist.

We reset the BIOS to factory defaults

The simplest and the hour dієviy sposіb fixing problems from computer entanglements. If your mood is not the best, it is possible to help you.

• turn off the life of the computer and remove the cover of the system unit.
• find a coin-cell battery on the motherboard and pull it out of the socket.
• close the contacts of the battery nest, for example, for an additional twist;
• install the battery on the plate.

The second option for resetting the BIOS is with a Clear CMOS jumper. Її it is necessary to take і for 15 - 20 sec. and move to two land contacts, after which turn on the middle. Other jumper is also called: CL_CMOS, CCMOS, CLRTC, CRTC and other.

After that, how to perform these operations, connect the computer's life and try to turn it on. If the problem is solved, the reason was in an incorrect BIOS Setup configuration.

All applications are included

Even though the first method did not help, I gave a demo. Let's try to turn off the setting, the neobov'yazkovy successful start of the PC. For which it is necessary to prepare a steel, covered with an insulating material (polyethylene, gum, plastic, thin wood), on which stand you choose.

Let's get started:

• remove the life of the PC and remove the cover to the case;
• remove expansion cards from the slots of the mother board, remove living things and interface cables, remove memory bars;
• remove the motherboard from the case, put it on the table and look for artifacts - blown capacitors, overheating (darkening and deformation of plastic parts), mechanical damage and other defects;
• if there are no artifacts - insert one memory bar into the slot, plug in a video card (likely not allowed), monitor hard drive that block of life;
• move the life block into the electric line;
• to close the contacts of the on button with a twist - Power Switch (can be signed as ON, PWR_ON, PC_ON) - the process is similar to raising the computer to pushing the button.

Yakshcho vy bachite on the monitor operating system- mean zbіy viklikaє one of the vimknenih outbuildings. Well, as for the cream wrapping of the fan, we don’t see anything again, we’ll try to find out more in detail.

• Start the system. Carefully touch your hands to the processor heatsink and the great nodes of the motherboard - microcircuits, mosfetiv thinly - in the norm, the stench can be warm. Strong heating (do not get drunk!) - talk about the inadequacy of the elements (defective soldering, short circuit), and the daily heating (room temperature) - show, more, those that the vuzol does not take the voltage of life.
• Turn off the life of the PC. Remove the memory bar, see the oxide ball on the її contacts, use the school buzzer, blow out the slot, it was out of the blue, and put it back. Activate the computer. As the problem goes away, the reason was in the filthy contact of the RAM and pay the rose. If you don't go wrong - put the bar in another slot - it's possible, you're guilty.

Replace the components on the reference book

Joden did not help out of the ways? Leave the rest that you can grow at home - by means of changing the attachment of a PC to robots, wisely, summarily with the system. Prote є rizik їх naughty.

As such, there is no such possibility, and also with the described problems on the laptop - the only option that is left out is to return to the service center.

Buvay, if a radiant koristuvach comes home, presses the button to turn on his trusted friend, but to mow. The computer just won't turn on. People begin to panic and call, we know, if we want to understand at computers, and if, in a stupor, in view of such direct food, without explaining the reasons for that particularity, we don’t know what it is. І garazd, if the equipment was turned on to start the HV, and if so, is the launch necessary for work purposes?

The computer just can't get the hang of it, that's all. There is a reason for that, and not one, that without a description of the features it is impossible to determine. And from even more respectful, to a sign of breakdown, everything can be put down without difficulty. Such situations are blamed for various reasons. Acts from them, after problems, shout out only hysterical laughter, and otherwise, empty the hamanets.

Buvaє, if a person only comes to the apartment, or only they slip and immediately turn on the PC. And wine, infection, does not get in. Think about why the reason for such a tragedy takes a lot of time, but in reality, the electricians simply don’t appear (even a TV, the light and other outbuildings were not turned on at that hour).
It's simple to overthink everything, and it's not a good idea to crawl on the Internet for such situations. But it is possible and so, that all the equipment turns on, but the PC does not. Possibility that there is no electrical life in a particular socket.

Why is it so troubling, you know electricians, and you can change the axis on your own, by plugging other equipment into the outlet of the hair dryer. If wine does not work, then rosette is the reason. It is necessary to bring the block of life to the next door, and do not clean the socket itself until the master arrives. As if the reason is not in rosette, let's move on.

Live PC

It is possible that everything is good with the outlet, but the life still does not reach the computer. On the back, it is necessary to check the integrity of the cable and carry out a simple manipulation: twist it and insert it. As you can see by the length of the cord, it’s an hour for me to have a smitnik, then it’s better to work it out by buying a new one. Navіt akscho the reason for the nasty launch of the PC is not new.
Also, behind the system unit special button. They rarely squirm with it, but vaguely zachepit її, and then guess why the computer does not work as a whole really. Її it is necessary to translate into the position "Uvіmk".

Living block

If there is no problem in the outlet and the cord, if the problem persists, then follow the electrician. As soon as the cable goes to the block of life, there is a way for us. For the sake of it, people called out to everything they could. The computers of the first economy plan have life blocks. People do not understand until the end, how important this detail of technology is.

It’s not scary and the cost is 35-50 dollars. Problems will be more serious, as not only the PSU is broken, but also other parts of the motherboard or the video card.

Buy some new details and don’t varto, but you need to check everything. It’s easier to work for the obviousness of another, correct BP. If there is nothing like that, then you need a voltage tester. At roses, life between black and red wires can have a voltage of 5V, and between black and black - 12V. Vіdhilennya can be less in the range of 5-7 vіdsotkіv, even more, then the block needs to be terminated. In order not to cause problems due to non-production of other elements of the system unit, it is necessary to replace it yourself, and not to repair it.

If the BP becomes incompetent, then the stickiness of the internal zakhist may appear. It is necessary to wind the cable of life for a sprat of thinness and leave the computer not connected to the wire. As if the next wine still does not start, the reason needs to be found out otherwise.

Power battery

On the top of the motherboard is a small 3V lithium battery. She supports the memory system, from which they save custom BIOS. Checking the battery before buying a computer is even more tricky, even if you need to sort out the computer. That th reverse the practice of shdo old-fashioned look- hard to finish. And you can see it as a whole. Otherwise, she could lie in the warehouse of a sprat of rock.

If the battery is low, the BIOS systems are reset. A sign of such an inaccuracy may be the last good hour. Also, in case of problems with the battery, when the PC is turned on, save the BIOS settings. In a few fluctuations, the technique vzagalі vіdmovlyаєєє вмікатиєєє. It is also necessary to check the practicality of the tester's selections. It seemed like it didn’t work, otherwise there’s just no tester under your hands, you can replace it. Such batteries are sold at a skin computer store and cheap.

Processor and Hard Disk Re-Verification

Since the cover of the system unit was removed for rechecking the PSU and batteries, then you can look at the processor and the hard drive. To find out which processor is working, you need to take a new cooler, start the computer and put your hand on the radiator. If wine starts to heat up, it means that wine works. Ale is also wondering how the cooler works. If not, then the computer will be muted to avoid overheating, and the wine will not start up for sure.

Also, a hard drive can be a problem to launch. It is necessary to check that all plugs are connected to the new one.

Drank at the computer

If there is a saw in the middle of the system block, it is not surprising that the computer does not start. To solve the problem, you need a great pylosos. The whole purification process consists of a number of stages:

Viruses

The reason is that the computer does not penetrate through the yaku, maybe a virus. The stench melts with the help of a computer, viruses can be harmful in different situations. If a person is corrupted by the Internet, and in the new installations of the filthy antivirus, or if not, then all-world spider Viruses come to the computer quickly by Himself best method fight against the shkіdniks є Yakіsny antivirus. Vіn obov'yazkovo may be official, and yogo should be periodically updated. On tsoma software security you don't need to wait.

But there are such situations when the PC gets in, but the operating system does not. How can I run an antivirus on someone's mind? It is necessary to try to capture the rest of the configuration. For which laptop is on, press F8. After pressing the key, a menu will appear on the screen, in which it is necessary to select "Entering the rest of the configuration in the distance".

If you do not dare to run the configuration in the distance, then try to enter the safe mode. For which next to win F8. When pressing the keys on the screen, a special menu appears, in which it is necessary to select the row “ Safe mode". As soon as we started the OS, we gave the following steps like this:

• Go to the "Start" menu;
• Select the menu "All programs";
• Select "Standard";
• Vіdkriti vikno "Services";
• click on "Innovation of the system";

BIOS settings

More koristuvachiv navit and don’t know what the price is BIOS system. As a matter of fact, you don’t need to get in touch with the chain, it’s better to immediately solve the problem. If the PC does not start up due to incorrect BIOS settings, then you need to clean it up, throw it off, or turn it back to factory settings. You can name the whole process as well as you can. If the PC still turns on, but sometimes, it is necessary to enter BIOS when starting the system. To enter the new one, you need to press the Del key or F2 (deposit from the skin computer). Dali, at the menu (blue color) that you see, click on Load Optimized Files. If it doesn’t turn on in the blink of an eye, then it’s necessary to drop the BIOS in a different way.

At the same time, it is necessary to remove the cover of the system unit and find it in the middle of the motherboard. On the surface there is a Clear CMOS jumper, as we need. Її it is necessary to “settle” at the court contacts, or simply blanch on a sprat of khvilin. After that, put it back and start again.

Motherboard

As soon as the lashing is thrown off, the computer is cleaned from the saw and the block of life is all right, but the technique still does not fit in, then the best option is possible. Like the motherboard is broken, it’s worth flying into a round bag. Especially if you want to take a daily fee, so you can buy a new processor, RAM and video card. Zreshtoyu, I'll have to upgrade almost the entire computer. Well, if it was necessary to grow.

The process of replacing the mother's payment is not easy, when replacing the following, you need to insure the following factors:

• On the new board, such a rose for the processor is to blame;
• It is necessary to check the number of slots in operative memory, the stench is due to the same type (DDR, DDR2, DDR3, etc.);
• Hard disk connection can be similar;
• Number of slots required for payment required;

If you don’t lie, then vinikne is a new problem. Now the coristuvach will be tormented by food, which is why the new motherboard does not start. Also, the new owner can have other systemic adjustment, and reinstall the operating system.

It will be logical to feed, why not send the motherboard for repair? It is possible to work less in that case, as the service rate for repairs does not exceed 30% of the price of the bill. Repairing a part of a computer is a complicated process and there are no guarantees, but in the future it will be good practice.

If all possible methods are used to solve the problem of victoria, and the technique is not switched on, then it will not be confused. It is necessary to call out the master, to determine the cause of the failure and usun її.

In contact with

1. The first reason why the computer does not turn on at startup is that there is no life in the rosette.

Whether the reason for not turning on the electrical appliances should be repaired from the lifespan. If you find yourself in a future place, it’s easy to find a power outlet, for which it’s enough to take a lamp, a power supply, or be some kind of electric appliance and plug it into an outlet, so that the power supply is turned up, so your power outlet is right.

Obov'yazkovo inverted how many more outbuildings you have connected to the same socket, perhaps you have exceeded the maximum allowable value of the voltage due to what is being used and the computer is not turned on.

Then you need to turn on all the extensions and remove only the computer from the socket.

2. Another extended reason, through which the computer does not turn on at startup, is the life cable.

Sometimes you try to blame the situation that the computer does not turn on? And the reason for this is the sumptuous tidying up, as if from the wound she failed to put things in order in the office, and vipadically hooked up the darts of life to the computer. Obov'yazkovo perekonaytsya, that the cable of life is hard fixed at the roses of life.

It's no secret that a lot of virobniks are trying to save the way of all those who are cheaper, the cables for eating have also become no fault of this rule. It is also important to know the best cable of life, the best of all squishy, ​​thin and serve not for long. Because the problem is that the computer does not turn on, take a working life cable, you can plug it in from the monitor and plug it into system unit.

3. The third reason is that the computer does not work through the yak and the button on the block is turned off. It just didn’t sound like a bi, but someone won’t guess that there’s a button on the bloc. Sound out she's poofed in black color and don't be surprised, she's very well remembered. There are problems here that are blamed after buying a new computer and wondering why the wine is not turned on. The reason for this is the total choice of the computer, which, by the way of safety, has broken the life block.

The button on the block of life can be set to the position

But not at the right time, do not chip a small voltage jumper (sound the wine of an erysipelas color) on which it is written 230, otherwise burn the block of life and happen to buy a new one!

Tsei small jumper to serve for the robotic life block different types voltage. In our country, the voltage in sockets is 220 volts, and the axis in Europe is 110 volts in the lower countries. Therefore, the virobniks roam the universal blocks of life with a voltage switch. When buying a new power unit, do not forget to pay attention to the position of your voltage switch.

4. The fourth reason is that the computer does not turn on when the power unit is started, which is good. Most often, capacitors are blown in the living blocks, after which the electric coil is wound and the living block goes out of tune.

The reasons can be like a voltage surge and a cooling problem in the heating unit. In this case, it is not necessary to remove the block of life, which can be replaced by replacing only one or a few capacitors. So it is with haircuts that the voltages go out of tune with resistors and other elements. The block of life plays an important role, not only stabilizing and reversing the voltage, but also protecting the computer from the voltage streak. A good supple block of life with a strong haircut of the tension will take all the excitement on yourself and not miss the distance. Cheap life blocks for their inexpensive price can not cope with their functions and there are often fluctuations, if after cutting the voltage, the strum passes through the life block on another component such as the motherboard, so it’s not only necessary to replace the life block and the mother board. Buying a cheap living block, you threaten all your components.

5. As soon as you opened the cover of the system unit, you saw a sprat of centimeters in the saw, do not wonder why your computer does not turn on.

He drank us ahead of the cooling system, which would cause the processor to overheat, and then overheating of the entire motherboard. I also drank to love stuffing myself into a block of life, to bring it to overheating and get out of tune. So I saw a saw, I can blame electrical breakdowns, I drank shards for singing minds to conduct a strum. Yak її properly suck?

To use a saw, you will need: a saw, a penzlik, and a pranny. We take the pilosos in one hand, turn on the yogo, and in the other hand the penzlik and carefully throw off the mother’s board, we drank it into the pilosos, then we go through all the components, let’s take the cooler from the processor and clean the radiator for cleaning the cooling system. The final step will be cleaning the memory modules.

Carefully remove the modules of operational memory and wipe them with a penzlik, and for the shortest possible number of contacts, go through the contacts to the most important ones for olives and install the memory strips on the plate. It's not foldable to let your computer friend live.

6. Another reason why the computer does not turn on at startup is the bios, which is the power of the battery.

You sing-songly mentioned that after the computer’s skin upgrade, the date and hour are not lost. In order not to waste a lot of other data after the skin shutdown of the computer, a dynamic memory microcircuit with low energy savings was built into the motherboard. Precisely called CMOS memory, it stores information about the date, hour, password, and a lot of other important data. All mother boards have a lithium battery installed near the tablet. The stinks serve for the life of the energy of CMOS memory, so that all your settings are saved from the winding station. Ale, the term for the service of this battery of surroundings, on average, such a battery works 3-5 years, after which it is necessary to carry out a replacement. Selling stench at all computer stores. The first symptoms are about those that the battery has run out, the date that it has been constantly fluctuating, and an hour on the computer. Also, when the computer is turned on, it may appear that "CMOS-checksum error" is written, and in okremi modes, the computer stops mimicking or it mimics after one time.

Let's take a look at how to replace the battery.

After that, we replaced the battery, updated the bios, and chipped in for promotions, about which the evidence could be written on the screen. Do not fawn, if such a writing was written, so be it. It is better to enter the BIOS by pressing the Del button and save by pressing F10, after which the confirmation menu appears, we press the button on the English layout Y and press Enter. Now our customizations have been blocked and can be processed by our computer.

7. The reason for this is that the computer does not come into contact with the start-up hour - problems with the components or cables.

If you inadvertently hooked up your computer, and after the first wine has ceased to be connected, it means that you have a plume of life to the mother's payment. Correct the situation simply by unscrewing the cover of the system unit and respectfully look at the bundle of wires that goes from the unit to the mother board. Looking like this:

The plume of life is due to buti intrusions at the nest of the mother's board before the release of the latch. If you try to force wine not to the end, or start to see roses, then it is necessary to build it on the spot. You can also remove the CPU power cable.

Vіn tezh is guilty of buti connections to the nest until the full spratsovuvannya of the latch.

Dalі perevіryaєmo cable zhivlennya and transfer danih to zhorsk disk, qi cables often nasty trim and fall out of roses. It is enough to insert stronger and in the space of the connection to the hard drive and in the space of the connection to the motherboard. The transmission cable is the most problematic, as vіn spochatku maє small area of ​​​​reinforcement.

8. The attacking reason for not turning on the computer can become a component of the system unit. For the demonstration of a non-working payment, it is necessary to remove all components from the system unit, remove the motherboard and the processor from the cooler.

As in such a complete set, the computer vmikaєєє, it means not so bad, the motherboard with the processor and the block of life is in order and we connect other components in order, we repair from operational memory, gave other parts. As soon as the computer is connected, be it pay, when it stops turning on and starts talking when it is turned on, we knew about the fee, so it’s necessary to replace it.

9. The ninth reason why the computer does not turn on at startup is a problem with the cooling system

Cooling system with radiator and fan.

Hourly, the radiator accumulates a large number of saws and wines begin to foully cope with their functions.

To solve this problem, you will need to remove the cooler from the processor again, take a penzlik and carefully clean the radiator, so you can’t get away from all the saws with a penzlik, just like the fan and clean the radiator itself.

At the next stage, our fan will be reconsidered, he is not guilty of heeling heavily and goydatisya when pushing against the new one. Yet another show-off, how good it is to turn around. It’s not easy to over-read, we twist yoga with a finger and marvel at how many turns of wine we can make. The fan in a normal state is guilty of growing a sprig of wrappers in front of him, as if to swell.

Well, just like you tidied up your finger and the fan was rattling, you need to replace it. Out of the way, they can turn like bearings, and the wrapping mechanism itself. Deyakі raszbryat ventilator zamaschuit yogo i potіm vіn deyaky hour pratsyuє, but only tse timchasov come in. Better replace the fan with a new one

An important role of the cooling system is played by thermal paste.

It is necessary for the fact that the heat that is emitted by the processor is transferred to the cooler radiator more quickly, and the processor cools down more quickly. For an hour, the thermal paste hangs and the contact of the processor with the radiator becomes ineffective, due to which the processor gets very hot. Overheat the processor until the overheating of all components of the system unit, and until the processor itself is out of tune.

10. The computer may not turn on through the shutdown function of the life block, as it influences the voltage of the power supply. With a strong haircut of the voltage, so that the life block itself does not fail and all the components are connected to the new function and the computer stops working. To update the robotic computer, it is necessary to turn on the computer on a sprat of fluffy computer, re-enable it. For the whole hour from the block of life, there is a static voltage and the wind will turn to the pratsesdatnoy camp.

B common causeє short flicker. Viklikane out there can be adapters, a bear, a keyboard, a fire, be it an extension, connect to a computer.

Solution: turn on all attachments connected to the computer, turn on the computer and connect one at a time until the computer is turned off again. In this rank, we are signifi- cantly wrong attachment.

12. So by the very reason, the computer does not turn on through the yaku, maybe there are some spare components, as if the system unit was let in from above. At this point, parts of the internal components may break and the computer will stop working. More lovers of all problems virishuvati with a fist, as if buzzing or galmuє computer stench on a new one to hit with a hand or a foot and the computer became better pratsyuvati. In the wake of such events, in addition to the fact that I can see loops up to hard drive otherwise the plume of life, the deformation of the body is observed, and so the body is found on a sprat of mm in the form of a mat. pay in the warehouse of great practice, hit it so that the body has become snug to its own pay, after which on the mother board there is a short flicker and out of tune.

13. The remaining reason is the power button is broken. Vіdbuvaєtsya tse dosit often. Lamaєsya like the button itself - tobto zapadє i її do not push. So the button mechanism, visually the button is pressed, but the shards are not able to contact the computer. In such a case, to turn on the computer, you need to take the back wall of the system unit, know the group of contacts below, where the power button goes, know the wire with the letter PW, turn it off from the contacts and add a twist to these contacts, after which your computer turns on.

In these articles, the main reasons were considered, for which the computer may not turn on.

Just because the computer doesn't work, it still doesn't mean that some of the shoes were cracked, or a quick facsimile is needed, the body is too thin. The computer does not work for other reasons. Let's follow the tradition, let's take this moment on a few examples from practice.

I’ll immediately say: everything that will be described below needs to be considered, as the simplest version of the situation, if the computer is not turned on. It’s completely immovable that the reason for this can be criticized in something else: or else. If you have it, then for the sake of it, there are also articles on our website.

Here I want to talk about those who, behind all the suvorim "zadіznimi" problems, people do not make the simplest and most obvious speeches for an hour and even if the computer does not turn on - they can start a lot of work that inappropriate work.

For the cob, we can sort out the widest swing, if the computer does not turn on, we throw an ordinary koristuvach into a catatonic stupor and zmushu yogo press the “power” button to no avail, and then click maistry :)

Meister come, put one hand behind the system unit, work there and start the car. Koristuvach of satisfaction and joyfully distribute inexpensive zukerki and baked :)

With singing periodicity after that, yak light disappears computer won't turn on. Let's understand what you want. At the moment of a sharp drop, the voltage spratsovuє zakhist to the block of life. The voltage drops quickly, but for the rahunok of capacitor capacities near the block itself - not enough speed for the Zakhist not to catch up.

Note: At the yakіsny block of life, you can see the difference. The axis is the widest of them.

• OCP (Over Current Protection): anti-stringing strain;
• OVP (Over Voltage Protection): against voltage stripping;
• OPP (Over Power Protection): sometimes called OLP;
• OTP (Over Temperature Protection): overheating;
• UVP (Under Voltage Protection): undervoltage;
• SCP (Short Circuit Protection): short circuit type;

In this case, the computer does not turn on through the anti-voltage protection. She turns on the supply of the stream with the lines of life. It is necessary for the additional charging of the special capacitor of the circuit to be protected, which, when the accumulated charge does not allow the system to turn up. In order for the system to notice everything we need to turn on - pull out the power supply cable (220 V) from the power supply unit for 3-5 seconds and plug it back (we discharge the discharged capacitor).

In this rank, we "skidaёmo" Zakhist BP and vin can pratsyuvati far away.

Tse, what is called, - "classics of the genre" :) Now I want to talk to you about more atypical vipadias, if the computer is not turned on. In my practice, the stench began to grow sparsely, and I realized what was enough to tell about such a possibility.

So, let's say the "session was correct" :) On one of the working office machines, a USB mouse was installed with such an adapter to the PS / 2 port:

Mabut, the very same adapter with a plinth of an hour, having started a local short-circuit (short flicker) in roses, which automatically led to the spratsovuvannya of a viable scheme for the block of life. As a result - the computer didn’t get into it, didn’t get into the principle of Whoever connected the mouse itself through the adapter - it didn’t make sense, but after the connection, I’ll add it without intermediary to USB sockets, everything miraculously worked.

So scho - mayte on uvazі.

One more example: call the management - Computer won't start". I come - it's working, it doesn't start. I'm trying a couple, I'm sorting through the sound on the mist. No result. I'm taking the system unit to us in IT, I've decided to "analyze the benefits" :).

Using the test method, it was revealed that the reason that the computer did not start was an invalid keyboard (more precisely, a microprocessor). The keyboard has been replaced. Buvaє, scho from the non-practical keyboard, the internal system speaker sounds three short beeps.

And the axis is one more thing from my practice. Feel free to bring your home PC from our robot, like: computer won't turn on, I don’t know why, wonder, be kind. Why not help a good man, marvel!

I bring yogo to my office, pull it out of the box, put it on the table and conduct a visual survey. What can I tell you? In short, I’ll just show a bunch of photos:

What did the people do with the car!? І tsia yogo enigmatic phrase: " won't turn on, don't know why?..." :)

What do I want to use your respect for? Try to look at everything when diagnosing possible options. Think bigger, don't get hung up on some kind of "standard" translation of faults. If the computer doesn't get in, see, at the beginning, all the periphery and add-ons, the reason itself is in them? Well, even if the computer is not yours, do you guard the level of technical adequacy and literacy of your masters? :)

I sincerely wish you good luck in your hard work!
