Did you install the smc as zero? Did you get it from another motherboard?

 

[Instafixx]

What do you mean by zero? Yes I got it from another board.

What the client said about the failure appeared?

 

[Instafixx]

It randomly shut down- that is what he said

 

[2informaticos]

Do you get the SMC from same model donor board?
PLT_RESET_L comes high?
Tried known good BIOS?

 

[Instafixx]

Yes. Do you want me to try another SMC - just in case

 

[2informaticos]

"Yes" to all my questions?

 

[Instafixx]

PLT_RESET is high.
Smc from a donor board.

 

[2informaticos]

What about new BIOS?

 

[Instafixx]

Disnt try that yet - but doesn’t seem to me like a bios issue. Let me try and change the smc again
