Broken SMC?

Hi,

I have a Late 2012 Macbook Pro Retina 13. The laptop restarts every few seconds. I formatted the ssd, and tried to reinstall mac os, but still it would reboot/shut down itself. I restarted SMC, NVRAM a billion times. I even replaced the battery for a new one. I cannot even complete Diagnostics without the laptop turning itself off. One curious thing is that, it won't shut down when I boot with CMD+R option and download the operating system, but once it restarts to complete installation, the laptop starts the same reboot loop.

If any has any suggestion, I'd deeply appreciate it

Thanks

Sounds like the board is bad.

If you're seeing it when running Diagnostics, then it's safe to say it's probably not the OS. Recovery mode (CMD+R) is an extremely limited form of macOS, so there aren't nearly as many things running or needing to process.

Could it be a faulty SMC? sure. but it could be a host of other things as well. The best way to get a solution would be to have it serviced. A physical inspection will go a long way in determined what it's going to take to get it 100% again.

Important to mention that device is on the Vintage list, so support may not be directly available from Apple (depending on where you purchased it). Consider checking with some local Apple Authorized Service Providers and see if they can help.

Best of luck dude.
