    820-01041 SSD Power Buck converter

    Can someone give me a "normal" partnumber for this chip? As far as i see it has full short circuit to ground and i hope it did not pass 10.8v directly to the SSD. once again - macbook 15 2018 is a piece of shit which sucks water right into the SSD power IC, killing the SSD with zero data...

    IR Camera is not useless and it looks really great if you cook it well

    820-2936 keeps burning current sense resistors

    Waterdamage on U7000, traces to R7021, R7022 were corroded away, both burned to megaohm resistance. After replacing ISL and both resistors i got a fan spin as well as a smell of burned R7021/R7022 resistors. No shorted caps in this circuit, resistance to ground is also OK. No shorts on...
