  • 820 3437, No green light - PPBUS 8,23v

    Hey guys,

    working on 820 3437 board, apparently no signs of liquid or kind of stuff and no components knock off.

    This one sounds like a SMC problem.

    PPBUS - 8,23v
    SMC_RESET_L - 3.4V

    already did the SMC dancing with Flux, already replace U7100 for a new one.. No changes..

    My question is, can i replace the SMC from a 820 000165 donor board??? or i will need to buy a 820 3437 donor board??

    Thanks

    Why do you want to replace it so fast?
    Post exact diode mode readings for SCL/SDA of battery bus; also the voltages.

    In case of replace, MUST get it from 3437 board...

      i forgot to mentioned that i I had already measured the SCL/SDA ... and seems OK! i have learned from you..

      SMBUS_SMC_5_G3_SCL - 0.492V

      SMBUS_SMC_5_G3_SDA - 0.492V

      i will order a 3437 board and replace the SMC! And after that i will post the results! thanks
