Apple computers are highly reliable, but their owners sometimes run into trouble. Let's figure out what needs to be done in the case when the MacBook does not turn on. If you did not manage to flood your laptop and did not drop it on the floor, the problem can most likely be solved without going to a service center.

First, you should perform an external check to make sure that the monitor and power adapter are working. The first applies more to owners of Mac Mini and iMac monoblocks. Laptops manufactured prior to 2016 use the MagSafe magnetic port for charging. The power cord is equipped with a light indicator.

When properly connected, it should glow orange or green. The L-shaped magnetic latch can work even if the contacts have not had time to connect. In this case, the power cord is externally connected, but power is not supplied due to a slight skew. T-shaped latches of the latest generation do not have such a drawback. Make sure MagSafe is connected properly.

All 12-inch models, and post-2016 MacBook Pros as well, use a USB-C power supply that does not have a light indication. MagSafe remained only in Air. The cord of the new adapters has two identical connectors at the ends and is connected to the laptop and the power supply through the port.

Unplug it on both sides and plug it back in. The adapter can automatically interrupt the power supply when there is interference in the mains. To reset the triggered protection, unplug it from the socket for one minute. After turning it back on, the computer should start charging normally.

Reset NVRAM/PRAM

When the adapter is good, power is on and the apple is lit on the cover, but the screen is still black, you will need to reset the NVRAM / PRAM memory.

  1. Turn off the computer completely by using the power button. Turn it on and immediately press the combination shown in the screenshot.
  1. Hold down all the keys until the laptop starts to start, emitting a boot beep again. After the inclusion went well and we logged in, we need to check for updates. Click in the menu bar on the apple logo located in the left corner. Select the marked item.
  1. On the main page, click the indicated button to open the App Store.

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

Resetting the SMC

The SMC is responsible for the power functions. These include battery management, response to closing and opening the lid, the operation of some system sensors, and interaction with peripheral devices. In any case, if your Mac doesn't seem to be working properly, forcing the controller to restart may fix the problem.

For Aimak monoblocks and all Mini versions, it is enough to disconnect the power cord for 15 seconds. Wait at least another five seconds before switching on again. For portable computers, which include all versions of "Air", "Pro" and 12-inch Retina, perform the following steps.

  1. Completely turn off the device using the menu item shown.
  1. Disconnect the power cord. We press the three keys indicated in the screenshot in the left corner simultaneously with the power button and hold for ten seconds. Connect the power adapter back and turn on the laptop.

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

Consequences of the upgrade

Apple has made upgrades almost impossible in models of recent years. In earlier MacBooks, the user could replace the memory strips on their own. The operation is simple in principle, but requires the correct selection of modules. If, after the upgrade, the laptop starts beeping during the power-on process, this indicates problems with the new memory.

Signals in this case are given with a pause of five seconds. Depending on the model, this may be one repeating beep or a series of three consecutive beeps. The only way out of this situation is to reinstall old modules or buy suitable ones.

Finally

If resetting the NVRAM and SMC doesn't help, then your Mac is in serious trouble. The best solution would be to contact a certified service for professional diagnostics. Keep in mind that for a year from the date of activation, your MacBook is covered by Apple's limited warranty and some repairs are free.

Video instruction

In the video below, you can see firsthand how the described operations are performed by a professional.

With the release of OS X Mavericks, we began to often encounter system freezes that we had not encountered before. Once you turn on your Mac, it loads correctly (first it shows , then the “wheel spins” under the apple) and freezes at the stage when the user should be logged in. The screen turns black and it seems to you that the computer simply freezes, or its video card or display does not work. But... If you move your mouse or touch your Mac's touchpad, you see a perfectly normal cursor that moves properly and doesn't look like a fatal error. Typically, our customers experience these symptoms after trying to install any system updates.

A biased study of the error led to the conclusion that neither resetting PRAM / NVRAM, nor resetting SMC, nor reinstalling the operating system (including deleting the System folder from the disk root) lead to the desired result. Everything is quite logical: freezing occurs not when accessing the system, and at the stage of accessing the user, and therefore, you should look for the source of the error outside of OS X. Apple's advice to combat this ailment in most cases comes down to formatting the system disk, installing a clean copy of the operating system, and restoring from a Time Machine backup . But there is a more effective way, similar in effect to magic.

But first, let's make sure you know your username and password. There should be no questions with the second one, but we usually don’t enter the login by a hundred times a day and we may be wrong about it.

  • Do you know? Great, skip this part and go straight to the action algorithm.
  • Not? Forgot? The easiest way to find out your "username" without having another Mac is to start the computer in Single user mode:

Wonderful! We have the username, remember the password (if the password is forgotten, we have a publication on how to use it, the second way, turning on the super-user). Let's start restoring the computer:

  1. Turn on (or restart) the computer safe mode. To do this, when you turn it on, press and hold down the ⇧Shift key.
  2. When the “thermometer” of the system loading reaches the end and the system boots up, we wait for the appearance of that very ill-fated “cursor on a black background”.
  3. Enter the first character of your username and press the Enter/⏎Enter key on your keyboard.
  4. Enter your user password and press the Enter/⏎Enter key again.
  5. We are waiting for the end of the system setup and restart the computer in any way you know.

Hooray! Your system has been restored! With a great-o-o-o-o-o time saving... We do not quite understand how it works, but it really works. This is evidenced by the numerous positive reviews on the Apple discussion forum and this fact is confirmed by our own experience. It remains to thank

If the MacBook does not turn on during normal system startup, do not panic. According to the experience of repair shop specialists, almost every second device with which something similar has happened easily restores its working capacity. The owner of the MacBook does not even need to carry it to the service.

This material reveals questions about what to do if the screen of an "apple" laptop turns black. How to solve the problem yourself, and when you urgently need to carry the device to the service - you will learn from this article.

The first step is to check the monitor. There is a high chance of display failure. Maybe it's just him, but with the "stuffing" everything is in order. If ventilation noises are heard during the startup process, the indication is displayed and the operating system loading melody is heard, but the display is black - 100% the source of the problem in itself. Nothing can be done, you have to go to the repair shop.

It would also be nice to check the power if the black macbook remains so for a long time and the operating system interface is not displayed. The most common reason why MacBooks refuse to turn on is a complete lack of power. Therefore, when such problems appear, you need to follow these steps:

  • double-check the correct connection of the power cable with the socket and adapter;
  • inspect the outlet for operability;
  • check cords and adapters on other gadgets;
  • see if the structure of the charging plug is broken, clean it from dust particles;
  • find out if the battery has failed.

If there are problems with one of the points above, correct the situation. After that, your device should start up as usual. If this does not happen, refer to other methods.


We reanimate the MacBook by other methods

1 One of the most common reasons for a MacBook to fail to work is a malfunction in the functioning of the controller or memory elements. Rebooting and turning off the power for ten seconds can fix these problems. 2 If the display is black, you can try resetting the system controller. It is carried out by successively pressing the elements "Option", "Control", "Shift" and "Power". The power cable is connected to the device, and the elements are released all at once at the same time. After that, you can turn on the gadget. 3 Another method to remedy the situation is to restart the PRAM/NVRAM. The operation is carried out by pressing and holding the elements "Power", "Option", "R" and "P". Then all that remains is to wait until the display turns gray and reboots. 4 The reason for not turning on the "apple" laptop may be a power failure or power surges. Power is controlled by the Power Manager software. In case of trouble, he puts a block on turning on the device. If this happens, you will need to disable such a manager action. By the way, when the device overheats, it also turns off. You can turn it on only after 100% cooling. And you need to act according to such an algorithm. First, disconnect the device from the mains and remove the battery. Then press the "Power" element and do not release for 5-10 seconds. Place the battery back. Try to restart your MacBook. 5 If the "apple" laptop of any line does not start after the update, boot it in safe mode. During the launch process, hold the "Shift" element.

Defective video cards in MacBook Pro

For this reason, MacBook Pros released a few years ago refused to work properly. After it was reported that the company, at its own expense, would replace defective Nvidia video cards. Most often, such malfunctions were observed in devices with displays of 15 and 17 inches.

The main sign of a video card with marriage is signal distortion or its absence. The largest number of devices with a similar malfunction was released in 2007-2008.

To replace an element, the owner of such a MacBook should contact the company's company store or a certified repair center. If the tests confirm that the video card is defective, it will be replaced with a new one free of charge.

But it is unlikely that today MacBook black can be caused by the marriage of this element. Because, in principle, few people use devices 10 years ago.


Other ways to start the system

If the macbook refuses to turn on, and the black screen does not respond to user actions, you can try these other ways to bring it back to life:

1 Perform a forced reboot. Sometimes the device "hangs" and does not want to respond to requests. There is nothing left but to resort to a reboot in forced mode. For this purpose, press and hold the battery for 8 - 10 seconds. After that, he is released, and the Mac turns on as always. Despite the apparent ease of the method, you should not resort to it often. After all, a complete loss of data can happen! Use it only as a last resort. 2 Prevent entry on the machine. If you used such a not very safe method, but want to temporarily deactivate it. It is required to press and hold the element with the arrow pointing up in the process of switching on - as soon as you find the indication of the loading operation. The login screen will be displayed forcibly, where you will need to drive in password characters to enter the account. 3 Run from the NetBoot image. During the reboot or startup process, you need to press and hold the “N” element. This will provide access to the operating system. It is stored on the server and can now be installed over the network. 4 Run the Apple Hardware Test diagnostics. The operating system has "native" diagnostic methods. They allow you to identify hardware problems. Launching this software is easy. For this purpose, you need to hold and hold the element “D” while turning on the device.
