Hello. Rookie question - please tell med if further info is needed.
I need help with mbp 2017 tb (A1706 - 829-00923-A) The story is as follows; Mbp is handed over because it shuts down in use. Takes after shut down 0.040 amp and 20 volts. If I remove the battery and start it, it boots normally and works for a while. But shuts down again. The fault is periodic and there are no short circuits. I have replaced the CD3215 controllers (thunderbolt ROM U8090…) on both sides, but the same error continues. I have measured most through, but found no errors. I have two logicboards with the same error. Does anyone know of a solution or an idea for where to start searching? CD3215 has not been reballed/changed but this is my next attempt. Battery replaced with a new one - same problem. The mbp was handed over with af exploded battery.
Greetings from Morten

Did you test with known good battery?
If still shuts down, then no reason to touch USB-C area.

Does it turn off starting in SMC bypass mode?
Try your USB test macOS too.

Clean ME BIOS worth to try also.
