Imac shuts down by itself. IMac shuts down on boot. Why did the computer turn off

Quite recently, something strange began to happen to my computer. Not for no reason, in the process of work, the computer began to turn off, as if the power was turned off. After that, the system was booted only through the restoration of the operating system, and this is a very long time, and the situation itself, to put it mildly, is unpleasant.

We are looking for the reason in the wiring

At first I thought that there were problems with the electrical wiring in the apartment, power surges or poor contact in the sockets. But a group of computer devices are powered by simple diagnostics of the electrical wiring and the bulkhead of the block of sockets, it became clear that the electrical wiring of the apartment had nothing to do with it.

It became clear that something terrible had happened, or at least a problem with the computer itself was on the doorstep. If I understand wiring and everything related to the wiring of an apartment professionally, then with computer repair, I am a complete zero. The "hardware" of this little machine is beyond my control.

We are looking for repair specialists

The situation was complicated by a computer model not quite standard for Russia, this is an Apple iMac computer, for some reason it seemed to me that imac repair would be problematic.

Googling my problem, I quickly found practical advice on how to disassemble and what to do with the machine. However, the prospect of disassembling the candy bar, without practice, strained. Previously, I disassembled and even assembled computer blocks, but it was under the "supervision" of a professional, and it was not an Apple candy bar.

Throwing away the solution to the problem on my own, I had to contact my friends and then, as I expected, there was an ambush, no one dealt with imac.

The time has come for the next logical step, to look for professionals “on the side”. By definition, I refused private traders, but I did not find a repair office, pleasant in all respects, so quickly.

My criteria for choosing a repair office included several parameters:

• Strict specialization in the Apple line;
• Home repair;
• Repair warranty;
• Advanced repair including macbook repair;
• A clear website and a reception desk in several cities were a great addition to the firm's solidity.

I will not bore you with the repair process, and there is not much to bore, everything was quick and simple from the outside. I'll tell you what the problem was.

Why did the computer turn off

According to the invoice, this repair is called "Cleaning the cooling system with replacement of thermal paste". Exactly. It's just that the "car" got clogged and clogged with dust. When working, it began to get very hot, the temperature rose to unacceptably high, and the computer fell, provoking an emergency exit from the operating system.

Output

The electrician is not always to blame for everything, and the devices burn not because of electricity, but because of ignoring the rules for using household appliances.

If you observe the MacBook shutting down for a while, do not try to charge and turn it on many times, as doing so may make the situation worse. In this case, you need to act differently - you need to establish the cause of the breakdown as soon as possible. Diagnostics will help with this. It is necessary to take the computer to a service center, since the diagnostics are done on special equipment. The sooner the breakdown is detected and fixed, the cheaper the repair will be. Diagnostics with us is free, it gives an exact answer to the question of why a MacBook laptop turns off on its own and spontaneously.

Reasons why MacBook shuts down

If the MacBook turns off during the game and during work, that is, under heavy load, then the problems may be as follows:

1. No voltage is supplied to the MacBook Pro, MacBook Air, that is, it does not charge normally, it also means that the battery will have a minimum charge capacity, and therefore the MacBook turns off. Replace the external power supply - the reason is in it.

2. If the connector itself is damaged, it is loosened, there are cracks, then in this case the Apple MacBook can be charged or not - accordingly, the battery capacity will be minimal. You need to change the connector.

3. If the cooling system on the MacBook is dirty with dust, overheating will occur. Because of this, the MacBook turns off immediately - you need to clean it.

4. When the video chip or south bridge fails, in this case the MacBook is turned off when it is turned on.

If the MacBook works from the mains and does not turn off, then 80% of the problem is with the battery, in 20% of cases it is the battery charging controller.

Real life example:

One of our clients asks what to do if the MacBook Pro, Air constantly shuts down, and then works normally again for a while. He's at a loss because the computer works fine, but why does the MacBook shut down by itself? We were able to answer him only after the diagnosis. It turned out that the connector in the laptop was damaged in some places. Therefore, the computer can be charged or not, which means that the battery capacity is always minimal. We suggested replacing the connector with a new one. After the repair, the Mac charged and worked fine.

What if the macbook reboots itself? Many people believe that this is due to some programs that you have installed, so this is possible. Others believe that they have viruses appeared on mac, in this I can reassure you, the percentage of virus infection is very small. Then why did your MacBook reboot itself and what to do about it? Obviously you have downloaded and some updates have been installed that required a restart for the changes to take effect. This can be, but such reboots are insignificant, and in most cases, the user must allow the reboot himself.

If this happens often, and the Apple computer starts to make you nervous with its strange reboots, then sound the alarm and carry the device to the service center not necessary, at least until we try to fix the problem ourselves.

After a long search on the Internet about why the macbook is rebooting, I realized that it was useless to search until I found a discussion in the official technical support on the apple website. And it turned out to be one of the hotly debated topics. The problem is in the Spotlight program, for some unknown reason, the search index is damaged (for quick searches on the computer, spotlight is used, this search program creates special index files that help it find files at high speed), and this is damage, or in other words the failure causes the system to reboot.

Solving the problem with restarting your Macbook.

The solution is very simple, all we need is to reset the spotlight settings and load them over again. To do this, follow our step-by-step instructions.

1. Open "System Preferences".

2. In the window that appears, open the "Spotlight" program

3. Go to the "Privacy" tab
