Hello, I am new to switch repair but want to get good at it. I have a device now that tells me amps and volts when plugged in. Unfortunately I cannot use it with the OEM switch charger, but in both directions it gives me 0amps 5v. I’ve tested for some shorts but haven’t found any. I just recently found out I can test individual pins when in diode mode by touching ground and the pins but I don’t know what the read outs should be for BQ24. I looked up the data sheet on TI website but I don’t really understand it. Anybody know any good videos for it or have any tips on searching for faults on the motherboard?

Here a good source to start.
This is usually related to but not always 100%:
USB C Charge port
M92T36
P13USB
BQ24193
If you get a board that has previous work always check ic orientations. I have fixed quite a few failed repairs by simply putting ic the correct way.

USC bridged points can cause wrong readings and or damage onboard ics. If usb looks physically damaged always remove then run tests.
