- Make sure the computer is turned on and connected to the power source (even if it is a laptop, the battery could be discharged).
- If you use an external display, check whether it is connected to the device.
2. Turn off and turn on Mac
The next step is to restart the computer. As a rule, it allows you to restore access to the PC and eliminate the problem of the black screen.
- Hold the power key until the device turns off.
- After some time, turn on the computer again.
Often this happens enough, especially if the black screen appeared after updating the system.

If Mac constantly hangs on a black screen when waking, you may need to reset the system controller and NVRAM memory control.
On the MacBook Pro this can be done as follows:

If you have already tried all previous options, and the black screen remains, you can try to reinstall the operating system. You can reinstall MacOS without disk formatting, but it is recommended to first back up.
5. Contact technical support service
Nothing helps? In this case, you need to contact Apple Support or attribute the device to the service center. Perhaps the problem lies in the "hardware" of the computer, although this happens extremely rarely.
In some cases, Mac users may encounter a system crash when the black screen is displayed when the computer is attempted to exit sleep mode or the user opens the MacBook cover, although the devices are in an active state, which indicates the key backlight or sound warnings. If there is a similar problem - do not panic. Most likely, you can cope with it on your own using the instructions published below.
1. Check the screen brightness and power brightness settings.
Before performing any actions, make sure that the screen brightness is at the maximum level (you can enlarge the brightness of the F2 key), Mac works and connected to a power source (even a laptop, since the battery could be discharged). If Mac uses an external display, make sure that it is also enabled.
2. Turn off and turn on Mac
It is often shutting down and re-enabled a computer will be enough to solve the problem of the black screen when exiting sleep mode. You can implement as follows:
- Press and hold the power button to Mac until the computer turns off.
- Wait a few seconds, and then press and hold the power button until Mac starts uploaded.
3. Receive SMC, NVRAM
If Mac repeatedly displays a black screen when output from sleep mode, reclaim the system controller (SMC) and NVRAM memory.
Owners of modern MacBook models can do the following:
- Turn off Mac;
- Disconnect the power cord;
- At the same time press and within 12 seconds to hold the combination ⇧Shift + Control + ⌥Option (Alt) + Power Button;
- At the same time release the keys, connect the power cord and turn on Mac;
- Reboot Mac and after the audio signal when you turn on the computer for 20 seconds to hold four clays ⌘Cmd + ⌥Option (Alt) + P + R To reset NVRAM.
In most cases, the SMC and NVRAM reset will help eliminate the problems associated with the display and power supply of the device.
4. If the problem is still relevant, reinstall MacOS
If you reset the SMC and NVRAM settings, increased the screen brightness, made sure that the computer is enabled and connected to the power source, but Mac continues to display a black screen when you exit sleeping mode, you must reinstall the operating system. It can be carried out without formatting hard drives, but it is better to progress and make backup copies.
5. Contact Apple Technical Support
If the above methods did not help eliminate the problem of the black screen, contact Apple specialists. In rare cases, the reason for this situation can be wounded in hardware or related to other unnoticed failures.

The MacBook Owner does not even need to carry it into the service.
In this material, questions are revealed about what to do if the "apple" laptop screen became black. How to solve the problem yourself, and when it urgently needs to carry the device to the service - learn from this article.
First of all, you need to check the monitor. The likelihood of the dispersion breakdown is great. Maybe it's only in it, and with the "stuffing" everything is in order. If noise from ventilation is heard during the start-up process, the indication is displayed and the melody of the loading of the Operations is displayed, but the display is black - by 100% the source of the problem in it itself. We can not do anything, you will have to go to the repair shop.
It would be good to check the power if the black McBuck remains such for a long time and the interface of the Operations is not displayed. The most common cause of mabukov failure from inclusion is a complete failure. Therefore, when such problems, you need to perform such steps:
- double-check the correct connection of the power cable with a power outlet and adapter;
- inspect the outlet for health;
- make checking cords and adapters on other gadgets;

We reanimate MacBook by other methods
1 One of the common causes of McBuka's failure to operate-outages in the functioning of the controller or memory elements. Eliminate these problems capable of rebooting and turning off the power for ten seconds. 2 If the display is black, you can try to reset the values \u200b\u200bof the system controller values. It is carried out by serially by pressing the elements "Option", "Control", "SHIFT" and "POWER". The power cable at the same time is connected to the device, and the elements are released at once at one time. After that, you can turn on the gadget. 3 Another method of fixing the situation is a restart PRAM / NVRAM. The operation is carried out by pressing and holding the "Power" elements "Option", "R" and "P". Further will only wait to wait until the display becomes gray and will not reboot. 4 The reason for not the inclusion of a "apple" laptop may be a power error or voltage jump. Power is controlled by Power Manager software. In case of trouble, he puts the unit to turn on the device. If this happened, you will need to disable such a manager. By the way, when the device overheats, it is also disconnected. It can only be turned on after 100% cooling. And you need to act on such an algorithm. First, disconnect the device from the network and remove the battery. Then press the "Power" element and not to release within 5-10 seconds. Place the battery back. Perform an attempt to repeat MacBook. 5 If the "apple" laptop of any line is not started after the update, perform its load in safe mode. In the starting process, the SHIFT element hold.Defective video cards in MacBook Pro
For this reason, MacBook Pro, released several years ago, refused to work normally. After it was reported that the company at its own expense will replace NVIDIA video cards with marriage. Most often, such faults were observed in devices with displays of 15 and 17 inches.
The main sign of the video card with marriage is the distortion of the signal or its absence. The greatest number of devices with a similar malfunction was released in 2007-2008.
To replace the element, the owner of such a MacBook should contact the company's company store either in a certified repair center. If the tests confirm the video card defect, it will be replaced with a new one for free.
But today today MacBook Black can be caused by a marriage of this element. Because in principle, few people use 10-year-old devices.
Other ways to start the system
If MacBook refuses to turn on, and the black screen does not respond to the user's actions, you can try more such ways to return it to "life":
1 Perform a forced reboot. Sometimes the device "hangs" and does not want to respond to requests. Nothing remains here, how to resort to a reboot in forced mode. For this purpose, pressing and holding the battery is carried out within 8 - 10 seconds. After that, it is released, and the poppy is turned on as always. Despite the visible ease of the method, you should not resort to it often. After all, the full loss of data may happen! Use it only as the last measure. 2 Prevent the entrance to the machine. If you used such a not very safe way, but you wish to temporarily deactivate it. It is required to press and hold the element with the arrow directed upward in the power process - as soon as you detect the display of the download operation. The input screen will be forcibly displayed, where you need to drive the password symbols to enter into account. 3 Run from the image of NetBoot. In the process of restarting or launch, you need to press and hold the element "N". So there will be access to the OS. It is saved on the server and now you can install it through the network. 4 Run the Apple Hardware Test diagnostics. There are "native" methods of diagnosis. They allow you to identify malfunctions. The launch of such a software is made easily. To this end, it is necessary to climb and hold the element "D" during the inclusion of the device.
