So last day I was using my MBP normally without any issues and shutdown before going to sleep. Today I press power button and the chime sound came very late, it boots up to a window where I put my password in and on the loading bar it crashed. It seems like it crashes after a certain amount of time after pressing power button.
I tried probably everything: NVRAM, SMC reset which doesn’t work. Boot on external drive, boot with another SSD, run diagnostics. Basically no matter how I boot my laptop power cuts of after 30sec or so.
Is this a sign of faulty motherboard?
