Ah.. I was most worried about this, but it turns out to be an IC issue.. :( I'll order 343S00438 and 343S00440 from AliExpress, replace them, and if it solves the problem, I'll leave a reply. Thank you! :)

It seems like the BoardView file doesn’t perfectly match my board. I have the 820-02016-A board, but I can’t find PMU_SHDN. C8315 (PP3V8_AON_VDDMAIN) = 3.78v PMU_SHDN = cannot find PMU_RESET_L = 0v

Sorry for the confusion. PP1V2_S2 = 0v PP3V3_S2_UPC = 0.58v PP1V8_AON_MPMU = 0v MPMU_VREF_ADC = 0.61v

Ah, I was being so dumb. 😭 Sorry about that! PP1V2_S2 = 0.291v PP3V3_S2_UPC = 0.415v PP1V8_AON_MPMU = 0.301v MPMU_VREF_ADC = 0.544v

I'm quite new to MacBook repairs, so I'm not entirely sure if I'm checking the right LDOs. Since I can find them using OpenBoardView, if there's anything else I should check, I’d really appreciate it if you could provide the names of the test points. I tried Googling for a list of LDOs, but I...

The picture is in diode mode, the value for L8100 0.026v. If this is correct way to reading values I will upload others too.

Firstly, all LDOs on U8100 are showing 0V. I checked L8100, L82B0, and L8270 with my multimeter in diode mode, but the readings seem a bit off. Sorry for asking such a basic question, but is it correct to measure in diode mode? I've been using it without any issues so far, but this time the...

The PPBUS_AON is showing 12.25V.. and I have found the following info. What should I check first? If the voltage is approximately 12.28-12.35V, it may indicate a communication issue between the SOC and PMICs, or corrupt firmware. Edit: Not possible to get it into DFU mode. PP3V8_AON_VDDMAIN...
