Why does not my MacBook air boot normally?
I have a MacBook air purchased in August 2014 that I've never had the slightest problem with. 5 months back It was updated to “Big Sur” and it there was no issue, it was working fine. After shutting down normally that day, I tried to start it next day, it showed a folder with a question mark and from then this is what happens:
1. I press start
2. After a few seconds I hear the chime, I can see that there is light in the screen and apple logo lighten up.
3. Nothing else happens and it shuts down after few seconds-- screen remains black and the keyboard is dark
Before it shut down it got updated to “Big Sur”
I followed all the steps outlined on apple communities: My MacBook Air it did not start, including trying to reset the SMC and the PRAM, but this did not help. I tried to get it into recovery mode but nothing happened no it is booting is safe mode. I tried to get it into recovery from Internet but it does not show any thing on screen.
Yes, I have checked the brightness of the screen, it has a good connection to power, the power cord light shows amber.
