Hi, I have a 2015 MacBook Air which suddenly does not start anymore. I have already tried tp reset the NVRAM and the SMC but no success.
I also tried to start it without a Battery and with a completley new Battery but also no luck. The only thing that happens after I switch it on is that the Fan starts running, but not on full speed. When I connect the charger, the LED goes green and then orange after a few Seconds.
Do I need a new Logic Board? Or is there anything else I could try?

Same thing just happened to me. Was working fine last night then today nothing.

I hope you found a solution?

try resetting PRAM and CSM reset, if doesn't work, go to service center and maybe time for a new notebook.
