    820-00165 fast fan and slow mac.

    good morning, using the HWMonitor the Memory Proximity sensors are at 129 degrees and the ASD test says that the SMC is with a problem. I replaced the Q5850 and U5810, but it didn't work. diode mode: SMBUS_SMC_3_SDA 0.717 SMBUS_SMC_3_SCL 0.716 Do you have any other sensors that I can test?

    820-00165 no install macOS Big Sur

    I can't read the Bios from the J6100 connector, so I removed it, to take the chance that it is interfering.

    820-00165 no install macOS Big Sur

    At first, the SSD already had Big Sur. The system boots up normally. The issue is that it won't let you install Big Sur from the installer.

    I tested another BIOS, in the tests it showed an improvement, but in the middle of the installation it shows an error. Is there any component that can be causing this?

    To clean the ME region I used the CH341a and the INTEL ME INJECTOR. UEFITOOL NE 57 to check the validation of the Fsys region.

    Good afternoon, this mac only installs up to Catalina, when I try to install Big Sur it shows an error "Download another version and update again", but this installer works normally. PP3v3_SuS when I force it to shut down it falls to 0V.

    I replaced the isl6295 and the SMC removed from the 820-00163 board, in tests at PPbus 12.3V I wonder if the SMC board 820-3332 works on board 820-3662 ?

    PVCCCORE_PH1_VCC oscila entre 0,354V ~ 4,661V. Achei que fossem U7210 e U7420, então os substituí, mas nenhum resultado. Testei sempre fora da mesa. PP1V8_AWAKE_SW3C 0 ~ 0,881V PMU_TO_SOC_AWAKE_PWRGD 0,170 ~ 0,827 V PP3V0_AWAKE_LDO7 0V ~ 1,435V

    Good afternoon, this mac had a shorted capacitor C7324 causing the PPbus to short, I replaced it but the PPBUS is at 5V. The Vcore resistance is 10 Ohms, too low? Voltage: PPbus: 5V; pp3v42 3.42V; ALL_SYS 0.223V pulsing; Vcore 0V;
