    yes

    PP3V3_S5_AVREF_SMC: 3.299V

    You wrote: "If board always starts in SMC bypass mode, should be an I/VSENSE sensor issue."

    So I'll check all the I/V sense signals at page 39 , 43 , 44, 51 etc....
    In the mean time I've noticed that it is not charging the battery as it's pulling only 30 mA, which could make sense as for security: I/V sense issue ---> STOP CHARGING Am I right?

          removed R2598, and tryied to start the board in normal mode: NOK
          On the board the pin1 ( SMC_N_FOLLOW ) is still 2.5V but as removed R2598: 0V on pin 2.

          Something is still preventing the SMC to turn ON the board:
          I will double check SMC_PBUS_VSENSE and SMC_CPU_VSENSE as they're higher that the other rails.....

            Removed R5385 for SMC_PBUS_VSENSE: NOK
            with R5385 still removed I've also removed R5309 for SMC_CPU_VSENSE still :NOK

            Next step will be to remove all the resistors that bringing all the I and V sense rails to the SMC, if still not OK so in that case I would suspect the SMC.......
            What do you think?
