Yes, I did mean SMC_RST was 0, and on the second measurement, SMC_RESET_L is 3.42V and not 0 I must've had my multimeter prongs on it wrong and I apologize, It happens sometimes, I'm not perfect.
I figured you would understand my abbreviation of RST because every signal you just listed was an...
8.62 V - Just Charger
1.8 V and dropping steadily - Just battery
5.99V - Bat & Charger
I'm sorry but I couldn't find the SCL and SDA lines related to the battery
Note: Sometimes the fan does spin fast and sometimes doesn't
This is what I did find...
Board powers on and boots fine with charger, known good batteries display 0%, dies, and it does not charge.
Corrosion around C1204, and U6101 area
I tested the continuity on U6101 and all the connections seem to be fine still
Hi, thank you for replying.
Took me a second to understand but I believe I got the right measurements.
All diode measurements were with the board unpowered, and red to ground.
Diode measurements are after the LDO
1.8V LDOA, 0.517
1.799V LDOD, 0.071
2.3mV 1v1 LDO, 0.509
3.28V 3v3 LDO...
Hi, I have a board that is only drawing 5V on all USB-C ports getting 0.168A on two ports, then 0.134A on one port, then 0.026A on another.
After taking out the board and ports it appears one of the ports on each side is covered in junk. I am currently using a fresh port and getting 0.137A
I had a macbook A1466 with corrosion all around U1930. It was originally drawing 30mA.
After replacing both resistors and U1930 it attempts to turn on drawing around 130mA with the fan spinning full blast
