MacBook Air does not care: see possible causes and how to solve

The MacBook Air may have several errors that make it not connect, especially if the model is older ( Apple’s ultrathin notebook has existed since 2008). The reasons for this may be linked to a defective charger, worn battery, and other hardware defects. In other situations, the computer may stop responding because of a critical software failure, for example. In any case, it is important to find out the reason for the crash to try to solve on its own or take the Apple laptop to the technical assistance. Check the MacBook Air for possible causes of error and learn how to proceed to fix the device.


Begin the investigation by the loader. On models of the MacBook made of MagSafe Magnetic Connector, make sure that the indicator light on the tip that fits into the computer is on. If the light does not come on, examine the cable and look for cracks that may indicate a break in the power supply from the power adapter to the notebook.

On the MacBook Air 2018, the task is simpler: leave the original USB-C cable aside and test another of the same type. Download Chain Even if it is not a 20 V and 5 A cable, such as a mobile phone charger, your MacBook should respond after a few minutes to the power outlet.


If the problem persists, the battery may be defective. Latest MacBooks do not allow you to remove the battery to check for power cord operation, but you can test a few tricks to make sure the component responds.

First, press the power button to find out if your MacBook Air makes a sound or displays lights, such as the Caps Lock indicator. If there is no signal, press and hold for 10 seconds, then release again.

If nothing happens, the battery may respond after a System Management Controller Reset. To do this, press the Shift + Control + Option keys on the left side of the keyboard and the power button at the same time. Hold for 10 seconds and release all keys at once. Then press the power button to turn on your MacBook.


A possible defect on the screen of the MacBook Air is easier to identify. When the display shows errors, the system starts normally and emits the typical boot sound, and other LEDs on the computer and the charger light up as expected. Also, remember to check if the brightness level is not at a minimum. If the computer is on, but the brightness key does not respond, try connecting an external keyboard to increase the brightness. Use the F2 key.

Operational system

When the MacBook’s failure is in the system, the computer usually turns on and displays some code or error symbol on the screen, such as an exclamation point. If this occurs, try the following:

  • Start in safe mode: Hold down the Shift key and turn on the Mac normally. Hold Shift until the end of the boot process.
  • Reset the non-volatile random access memory (NVRAM): Hold down the Option + Command + P + R keys and turn on the Mac. Continue pressing for about 20 seconds, when the MacBook Air may appear to be restarting.
  • If none of the above works, reinstall the operating system from scratch. You will need an active internet connection.
