If a MacBook Air shows a black screen, first see whether it is asleep or off: press a key, then hold the power button for about ten seconds to reach startup options. A black screen with the keyboard backlight or a Touch ID sound means the Mac is running and the display is the problem. Try an external display, raise the brightness, and restart; flicker on M4 Airs is reported by owners and is tied to the display driver rather than a failed panel.

Model-specific
What is true of this model and not of its siblings
- Apple silicon Air
- The M2, M3 and M4 MacBook Airs have no fan, so they throttle rather than spin up, and they start from the power button, which is the Touch ID key. Hold it for ten seconds for startup options.
- Repair cost
- A display repair out of warranty is among Apple's costliest Air repairs, which is why the external monitor test and a macOS update come first.
- Other models this page answers
- These steps also fit the MacBook Air 13-inch (M3), MacBook Air 15-inch (M3).
Stop boundary
When this stops being a self-service repair
- !If an external monitor works but the built-in display never does, book display service
- !If there is liquid or a crack, stop using it
- !If startup options never appear after ten seconds, contact Apple Support
