    820-00138 no power no green light

    I fixed a connector to power everything, I checked SMC and it seems to work I switched to u7100 and on ACIN I have 4.69v and on SMC_BC_ACOK I have 3v the ACIN value seems high to me, shouldn't it be 3.2V?

    A1369 It doesn't just turn on green light

    I suspected that he had been reflowed at the ram because some capacitors were missing, I began to detach on one side and I was lucky that after 3 modules the short was gone

    How do I see the ram that is short? In fact, I found a missing capacitor near a ram

    A1369 It doesn't just turn on green light

    So a short on the CPU? Either first I have to check U7801 or remove R1120 and see if the short is interrupted

    A1369 It doesn't just turn on green light

    I lifted L7330 the short remains on the 2nd I checked all the leveling capacitors and don't pull down PPDDR_S3_REG at this point is something after the boardview would look like a rhophore under a ram, lifted the ram?

    I found one that equals 820-3023 A but has a low insulation on L7330, as you advise me to proceed

    Removing R7913 The PCH is no longer hot, it also disappeared 3v3_S5 then I joined R7151 and R7252 but on L7220 always 0V

    820-3023-A No Power not charge

    Just out of curiosity, what do you mean by forcing 5V_S3?

    820-3023-A No Power not charge

    I eliminated the short by replacing C7252 I checked after L7220 and the low insulation disappeared but still nothing PP5V_S3 probably because of the PCH if I understood correctly
