    Macbook Pro 15" 2019 (A1990, 820-01814) CD3215 shenanigans

    Hi! Thanks in advance for taking your time reading this / helping me out .

    I have this MB Pro which had a defective CD3215C00Z. After replacing that one, I figured out that I needed to replace the other one as well since I only had CD3215C00 chips (without the Z at the end).

    Now the funny thing is where I replaced both the CD3215 chips, it takes 5V ~.32A and the other side that I didn't touch now takes 20V ~.45A (then drops down to .03A).

    Do I need to replace the 2 CD3215 chips that I didn't touch as well? Feels so counterintuitive so I'm having serious doubts...

    Any tips or advice is very much appreciated! <3

      So the 2 CD3215's that I placed could both be just bad? That would be hilarious...

      It takes 5v on one side and 20v on the other side with or without battery connected, should've mentioned that.
