A1398 820-00138-A no power and no green light

[hgoncalves]

Hi,

I have an A1398 820-00138-A with no power and no green light. It has no signs of liquid damage, and no story.

I have PP3V42_G3H, and PPDCIN_G3H, but i don't have SMC_BC_ACOK (0V and 0.542 on diode reading).

On R5187 I have 0V on SMC_BC_ACOK.

Shall I replace SMC?

TKS

Strange that you don't consider PPBUS_G3H important to mention.

SMC_BC_ACOK is controlled by U7100.

Hi,

I forgoted to mention it. Sorry.

It was the U7100. After replacing it, it powers on again.

TKS!
