Random power misfire, it will not turn on sometimes
when I turn on, 1 out of 5 times ,the keyboard lights on, but nothing on screen.
If I wait 30 minutes it might work again.
After powering up, does not crash.
It has passed all diagnostics and some stress tests.
Is there a particular part that can cause this? DIY fix?
(More specific that just the “motherboard” please)
Forgot to say - did SMC and NVRAM reset. Deleted OS and reinstalled fresh.
