Won't power on. Fan on for a 2 seconds and turns off, repeats
My MacBook Pro mid 2014 13” was all working and all of a sudden yesterday it turned off.
Things I did to check before opening my Mac:
- Shutdown my Mac by pressing power button for 10 seconds, and turned ON - tried resetting PRAM.
- Similarly tried resetting SMC.
Result: Nothing happened no chime or display.
So opened it and disconnected the battery tried with just main plug still same results.
But! I noticed that, when power button is pressed, fan spins for 2-3 seconds and stops and repeats. Then the CPU, SSD gets hot. I then removed the battery and power supply.
Last try, I disconnected SSD, side WIFI board and turned on, still same result.
If it is a logic board issue, anyone know which part failed it would be helpful.
If anyone recognize this problem, please help.
Thanks
