Hello, I have an 820-02020 M1 machine here with 5V and taking .450mA. This board has a ton of corrosion everywhere, some of which I have cleaned up. I have replaced the ISL9240. Currently, U8100 gets warm, but not burning. It sits at 40C under thermal cam. PPBUS_AON and PP3V8_AON both measure at...
Hello, I have a 820-01958 2020 MacBook Air. The board is taking 5V .23 amps on both ports, not looping. PPBUS_G3H is 12.3V. Corrosion was around the CD3217s. I have already swapped both CD3217s, as well as the ROM. I’m missing P5VG3S_EN. I have tried restoring with AC2. The device is recognized...
Hello, I have an 820-00928. Board came in initially with corrosion on U6500 and U6550. Replaced those, have replaced U7000 and Q7030, and Q7040 (due to PPBUS_G3H low). No shorts on PPBUS_G3H.
PPBUS_G3H is 0.75 V and slowly increases. It's weird because it will keep increasing if I leave the...
Have an A2179 MacBook Air. Board number is 820-01958. There was a little sticky substance and corrosion on C7670 and C7665. Board will take anywhere between 25 and 100 milliamps and then it will cycle, but the cycles are not consistent. PPBUS_G3H is 12.29 V with battery plugged in and without...
Hello, I have a 820-00923 No power. I looked the board over and found corrosion near U3100. I had no PP3v3_G3H but I removed corroded capacitor and got 3.3V on PP3V3_G3H. The problem is I plug in the charger to every single port and it takes 5v, 30-50 milliamps, and turns off. And the cycle...
Hello everyone! This is my first post here:) I am working on an 820-00850 that is taking 20v, 50-70 milliamps.
PP3V3_G3H: 3.36v
PPBUS_G3H 12.56V
The schematic I have says PPBUS rails have to be 13.1v, however on previous models of MacBook Pros, it is 12.6 that is normal. Am I correct in that...
