A black screen on a MacBook Air M4 has a particular signature in the community threads. Owners of the 13-inch M4 describe a screen that lights briefly on wake and then goes black again until you press the power button a second time, and others describe a black screen on every start with a responsive cursor that no troubleshooting step cleared. Those are different problems with different next steps. A wake that fails once is a sleep and display state, so wake it with the keyboard, raise brightness with F2, disconnect everything and update macOS.
A black start with a cursor is a login or graphics-layer fault, and the route is Safe Mode, then Recovery, then Apple. A Mac that shows nothing at all, no chime and no light, is the start-up case Apple's articles cover.

- Two threads, two problems
- One thread describes the lit-then-black wake; another describes a black start with a cursor; they have different fixes.

- !A black screen in Recovery needs Apple
- !A repeat of the lit-then-black wake deserves a service visit with the thread numbers in hand
- !A cracked or lined screen should be repaired
