I have a a Macbook Pro 15" Touch 2018 that was liquid spill at Q7065. Prior to clean the area the computer was turn on but won't charge the battery. After reflowing the area ultrasonic the logic board and dry out after dry out computer won't turn on anymore. I have 19v on the charger with 975mAh. I have to test all the power rail and found out that PP3V_S5 power rail and PP1V8_S5 are missing, these power rail coming from U1200. Any suggestions or input I would really appreciate. Question! What powering up the U1200 chip?
