Mac mini does not turn on. What to do if the Mac does not load and hangs on the Apple logo

What to do if suddenly laptop screen MacBook Air, Pro? Of course, in this case it will continue to work it will be impossible. First, we advise you to connect the laptop to the monitor and check if the image appeared on the external monitor. If it appeared, then the problem is in your laptop, or rather - either in the plume or in the matrix itself. If he does not show, as a rule, the problem is hiding in the gland. Consider possible options in more detail.

  1. First, check if problems do not appear when opening or closing the Lappleop cover. Often in the closed state McBuck is simply turned off or goes into sleep mode. When opening the screen turns on again. As a rule, the reason lies in the most mechanical switching button, which is most of all suffer and comes in disrepair through the dirt entering. In this case, she just sticks out. Users can simply pour it with liquid, as a result of which it can just close. The button is located in the most prominent place. As a rule, in the upper right corner, on the panel, where the display, or in the end. When malfunction, the power button must be replaced. Such a simple task takes quite a bit of time.
  2. If the monitor shows, but there is no backlight, mainly says that the inverter is damaged or the illumination lamp itself. These components are responsible for the display backlight. If the inverter is not badly damaged, it can be repaired, otherwise - it is changed to a new one. The lighting lamp is not subject to repair, only its complete replacement will help.
  3. If the matrix is \u200b\u200bblack, while on the sides there is a backlight or not, then the problem is the very hardware.

Consider in more detail possible options:

When the MacBook Air, Pro laptop display does not turn on

If the laptop is loaded, McBook and hangs everything.

  1. First of all, it is through a hard disk problem.
  2. It is possible that an error occurred on the hard disk.

A portable computer may also hang after obtaining mechanical damage or as a result of moisture inward.

If MacBook does not turn on - this is not a reason for experiences. According to the MacRepublic service center specialists, every second Apple laptop, which suddenly turned off and does not want to turn on, easily reanimated at home.

Our advantages

Consider in more detail how it happens.

Check monitor

First of all, you need to exclude the displays. Perhaps the MacBook PRO screen does not turn on, and the remaining system devices work properly. If the fan operation noise is heard during startup, the indication is running and the melody of the OS load, but the screen remains black, then lies in it. Change the problem only in the service center.

Check nutrition

The most common reason is the fact that PRO, AIR, RETINA, MACBOOK does not turn on - is no power. Therefore, when such problems occur, the following actions perform:

    Check power cord connections with adapter and outlet.

    Ensure the performance of the outlet.

    Rewrker cord and adapter on other devices.

    Check the integrity of the charging plug. Clear it from dust and garbage.

    Eliminate the likelihood of a battery failure


Other MacBook Enable Methods

    Failure in the operation of the controller or memory modules can also contribute to the fact that MacBook does not turn on. To resolve the failure will help reboot and complete power off for 10 seconds.

    If PRO, AIR, RETINA, MACBOOK does not turn on, you can try to reset the system controller parameters. Reset is performed by synchronous by pressing the "Option", "Control", "SHIFT" and "POWER" keys. In this case, the power cord must be connected to the laptop, and the buttons are released at the same time. After that, you can try to turn on the macbuck again.

    Another way to act, if the MacBook RRO screen does not turn on, - restart PRAM / NVRAM. The restart is made by pressing and holding the "POWER" buttons "Option", "R" and "P" until the black screen is changed with gray, and it will not be rebooted.

    A voltage splash on the network or power error can also be caused by the disclosure of MacBook. Power control is performed by "Power Manager", it blocks the inclusion of a laptop. Actions will help to disconnect the operation: such actions will help: when overheating McBook is also a shutdown. You can turn on the device only after complete cooling.

    • disable the gadget from the network;
    • remove the battery;
    • press the "Power" key and hold 5-10 seconds;
    • insert battery back;
    • try to re-enable a laptop.

  1. When overheated, McBook also has a shutdown. You can turn on the device only after complete cooling.

    If Pro, AIR, Retina, MacBook does not turn on after the update, the download is performed in a safe mode, while holding the SHIFT button during startup.

Many of you have probably heard that the Apple operating system is famous for its reliability and low number of errors and failures occurring. However, Mac OS, unfortunately, is not ideal and one day can neither with this just take and not boot.

Without a doubt, this behavior of your poppy can be caused by a number of different errors, which need to be different, but the author of this article is in recent times increasingly facing the situation when MacBook is not loaded after the next operating system update (Mac OS Sierra in this particular case) and makes three loud pisctionsrepeated with certain frequency.

Unfortunately, this can happen with each of us, and to contact the service center often happens and, of course, notice. Fortunately, there is an easy way to try before carrying your poppy somewhere. Judging by the reviews in foreign forums, it has helped to save funds to address the service, more than once helped such a "hint" and the author of this article. About him and will be speech. So what to do if you do not turn on MacBook?

Manifestation of errors when loading Mac

As mentioned above, a similarly computer can behave due to a number of different errors (at least 4, judging by the help on Apple's website).

However, in our case, the sequence of actions and the symptoms of the patient look like this:

  1. you have installed the update of the Mac OS operating system (or the computer installed it itself, if you are included auto update);
  2. when you turn on (reboot) your MacBook instead of the expected loading strips of the operating system, you saw only black (well, a slightly gray, the side lighting of the monitor still turns on) the screen;
  3. looking at this "light-black" screen you heard three long sounds like "Bip-Bip-Bip", repeated with a frequency of 5 seconds.

Carefully examining Apple's official website. We find symptoms and a description of our error:

"Three consecutive signals that are repeated with a five-second pause: RAM has not passed the data integrity check."

Okay, is understandable, this is the RAM error of our MacBook. But at least some way to solve the official somehow forgotten. But we found it, and it turned out it is simpler. Of course, it is not a fact that this method will help you 100%, but it is worth trying, because Many are works.

By the way, judging by the discussions in foreign forums, the following McBook models most often give out such an error and do not turn on: MacBook Air A1466, MacBook Pro A1278 and A1260. It is from the first we write this article.

Solving the problem - Reset SMC parameters

So if your MacBook Air, MacBook Pro, IMAC, Mac Mini or Mac Pro does not turn on and beeps - This signals an error associated with the RAM (RAM), which most often can be solved by resetting the system controller parameters (SMC).

Depending on what your device has, follow the algorithms below.

If you have a MacBook with a worn battery

And such are most of modern models, the following algorithm for you is as follows:


If you have MacBook with a removable battery

Although such, in my opinion, have not been issued for a long time, but just in case - we act as follows:


If you have iMac, Mac Mini or Mac Pro

That is, one of the stationary computers from Apple, then reset the system controller parameters (SMC) is even easier:


Using suitable for your poppy "But the way you will most likely see the usual Mac OS download window - this means that the problem is solved.

What does the SMC settings affect the reset

If you are not very well versed in computers or simply encounter such a procedure for the first time, before you have done the actions described above, it may arise a completely reasonable question: "Will I lose important data or settings on your MacBook as a result of a reset, because This procedure is partly similar to "Hard Reset" On some gadgets? ".

We hurry to calm you - no, you will not lose anything important. If you are really wondering, take a look at the list of functions for which the system controller is responsible (SMC), whose parameters we drop:

  • reaction to pressing the power button;
  • reaction to opening and closing the display cover on Mac laptops;
  • battery resource management;
  • temperature control;
  • summer Sensor;
  • external light sensor;
  • keyboard backlight;
  • status indicator management;
  • battery status indicators;
  • selecting external (instead of internal) video source for individual imac displays.

Alternative option - rearrange the RAM

If the option proposed above did not help and your MacBook is still not started, then you should try an alternative way. However, it is not suitable for any Mac computer, but only for those whose operational memory can be replaced, and not planning on the motherboard (as is done in most modern Mac models).

If you have one of these computers, then this option can help you, you just have to know how to get to the RAM slot. The algorithm of action is very simple:


That's all. Now you know what you can try to make first if your Mac does not start and beeps by the opposite signal. We hope that one of the proposed options will help you solve this problem and save a significant amount of money on accessing the service center.

Fair, not overpriced and not understated. The service site should have prices. Be sure! Without "stars", it is clear and in detail, where it is technically possible - the most accurate, final.

How many masters in directions

If you are always waiting for several engineers for each type of technology, you can be sure of:
1. The queues will not (or it will be minimal) - your device will take place immediately.
2. You give to the repair of the MacBook expert in the field of Mac repairs. He knows all the secrets of these devices.

Technical literacy

If you ask a question, the specialist should answer it as accurately as possible.
To make you imagine what you need.
The problem will try to solve. In most cases, the description can be understood what happened and how to eliminate the fault.

Apple computers are characterized by high reliability, but their owners sometimes face trouble. We'll figure it out what you need to do in the case when McBook does not turn on. If you did not manage to pour your laptop and did not drop it on the floor, the problem most likely can be solved without a hike to the service center.

To get started, perform an external check to make sure that the monitor and the power adapter are correct. The first is more relate to the owners of Mac Mini and the monoblocks of IMAC. Portable computers, released until 2016, are used to charge the magnet port MAGSAFE. The power cord is equipped with a light indicator.

With proper connection, it should be lit orange or green. L-shaped magnetic latch can work even in the case when the contacts did not have time to connect. In this case, the power cord is externally connected, but due to a small skew, the power is not served. T-shaped latches of the last generation of such a shortage do not have. Make sure the MAGSAFE is connected correctly.

In all 12-inch models, and after 2016 - and in MacBook Pro, use the power supply with a USB-C connector that does not have a light indication. Magsafe remained only in AIR. The cord of new adapters has on the ends two identical connector and connects to a laptop and power supply through the port.

Disconnect it on both sides and connect again. The adapter can automatically interrupt the power supply during interference in the power grid. To reset the worked protection, pull it out of the outlet for one minute. After re-enabled, the computer must start charging in normal mode.

Reset NVRAM / PRAM

When the adapter is working, the power is served and an apple is lit on the lid, but the screen is still black, then you will need to reset the NVRAM / PRAM memory.

  1. Fully turn off the computer by using the power button. Include it and immediately press the combination shown in the screenshot.
  1. Hold all the keys until the laptop starts running, making the boot beep again. After the inclusion passed normally and we are logged in, you need to check the updates. Press the menu bar to the apple logo located in the left corner. Select the marked point.
  1. On the main page, click the specified button to open the App Store store.

The automatic system will check the availability of updates. We install all available and if necessary, update OS to the latest version of High Sierra.

SMC Controller Reset

The SMC controller is responsible for the power supply features. These include the control of the battery, the reaction to the closing and opening of the cover, the operation of some system sensors and interaction with peripheral devices. In any case, if it seems to you that Mac works incorrectly, the forced restart of the controller can relieve problems.

For Haymak monoblocks and all MINI versions, it is enough to disable the power cord for 15 seconds. Before re-enabling, it is required to wait at least five seconds. For laptop computers, which include all versions of "Air", "Pro" and 12 inch Retina, carry out the following steps.

  1. Fully turn off the device using the menu item shown.
  1. Turn off the power cord. Press the three keys in the left corner indicated on the screenshot simultaneously with the power button and hold for ten seconds. Connect the power adapter and turn on the laptop.

As in the previous case, check and install the available OS updates.

Consequences Upgrade

Apple in the models of recent years have made an upgrade almost impossible. In the previously manufactured MacBook, the user could independently replace the memory bar. The operation in principle is simple, but requires the correct selection of modules. If after the upgrade in the process of inclusion, the laptop begins to sing, this indicates problems with new memory.

Signals in this case are fed with a pause of five seconds. Depending on the model, this may be one repeating beep or a series of three consecutive. The only way out of this situation is the return setting of old modules or purchase suitable.

Finally

If the NVRAM memory reset and the SMC controller does not help you, then your Mac has serious problems. The best solution will be the appeal to the certified service for professional diagnostics. Do not forget that during the year from the moment of activation on MacBook there is a limited guarantee of Apple and some types of repair can be performed free of charge.
