Hi everyone,
I have a MacBook Air A2179 in my hands that had power problems (5V to the USB-C port unstable).
I noticed there is liquid at U3200 and U3100 and have replaced them.
PP1V5_UPC_X_LDO_CORE : 1.575V
PP3V3_UPC_X_LDO : 3.280V
PP3V3_G3H_RTC: constantly fluctuating from 0.5V to 3.284V
I have isolated R6979,
Pin 1: 3.280V stable
Pin 2: 0.447 (diode)
PPBUS_G3H: 12.28V (with R6979 isolated)
PPBUS_G3H: fluctuates 5V -> 4V -> 6V -> 12.28V(when R6979 is present), and repeats in a loop
What should I do next?
