I have MacBook Air

When I start the screen gets black out also during work it's flickering and suddenly gets black out.

Pls help

shut down

disconnect all external devices

reset the smc

repeat this step two or three times

then boot into safe mode

then reboot normally.

if problems persist you may need to take it to an Apple authorized repair center for an evaluation.
