What are the common reasons for a MacBook Air screen to keep going black?
The MacBook Air screen may keep going black due to various reasons, including overheating, a faulty display, or issues with the graphics card. Additionally, a malfunctioning backlight, loose connections, or a software glitch can also cause the screen to go black. In some cases, the problem may be related to the MacBook’s power management system or a conflict with an external device.
To identify the root cause of the issue, it’s essential to observe the behavior of the MacBook Air when the screen goes black. Does it happen randomly, or is it triggered by a specific action?

How do I troubleshoot a MacBook Air screen that keeps going black?
To troubleshoot a MacBook Air screen that keeps going black, start by restarting your MacBook in Safe Mode. This will disable any third-party apps and extensions that may be causing the issue. If the problem persists, try resetting the System Management Controller (SMC) and the Power Management Unit (PMU). You can do this by pressing the power button, the Command+Option+Shift+Power buttons, or the Power button and the Volume Down button, depending on your MacBook model.
If resetting the SMC and PMU doesn’t work, try running a diagnostic test on your MacBook’s hardware using the built-in Diagnostic Tool. This will help identify any hardware issues that may be causing the screen to go black. You can also try booting your MacBook in verbose mode to see if there are any error messages that can help you diagnose the problem.
What is the role of the System Management Controller (SMC) in a MacBook Air?
The System Management Controller (SMC) is a critical component of a MacBook Air’s power management system. It is responsible for managing various system functions, including the display, battery, and cooling system. The SMC also controls the MacBook’s sleep and wake functions, as well as the keyboard backlight and other peripherals. If the SMC becomes faulty or corrupted, it can cause issues with the MacBook’s display, including the screen going black.
Resetting the SMC can often resolve issues related to the MacBook’s power management system. This is because the SMC reset process reloads the default settings and clears any corrupted data that may be causing the problem. To reset the SMC on a MacBook Air, press the Power button, the Command+Option+Shift+Power buttons, or the Power button and the Volume Down button, depending on your MacBook model.
