Had a weird one with a 2018 MacBook Pro board yesterday
Customer brought it in with no power. Found 5 volts on PPBUS_G3H but nothing else. Checked the CD3215 chips, one was stone cold. Replaced it, board powered right up. But then the left USB-C ports wouldn't charge. Spent another hour chasing a tiny crack in a trace near the port. Anyone have a good source for those ultra-fine gauge magnet wire? The stuff I have is too thick for this.

Actually, PPBUS_G3H is 12.6 volts on those boards, not 5. Might wanna double-check that.

Oh man, I've been there! My own boards probably have more jumper wire than original trace at this point.
