    Can I hook up an A2289's battery connector on the motherboard to a DCPS and power it that way?

    Hey!

    I have a Macbook with bad USB-C ports and after replacing the CD3217, the issue still persists. I need to back up 42000 photos to the cloud, and was wondering if I can wire up the benchtop power supply and get ut running well enough to get the data transferred or if that little ribbon that transfers the battery data will cause an issue.

    Thanks in advance

    Do not recommend any such bypass methods.

    Share full details of the issues. For each cd3217, check the ldo rails. Also, what is the origin of the replacement cd3217?

      T2 needs fully functional CD3217 (and correct firmware for each) to complete it's sequence. It'll just sit there on 5V otherwise. Charged battery is irrelevant as the T2 (SMC) needs to boot and pass control for the Intel sequence.

        Device started not charging and was stuck at 5v for charging. I had two donor boards that I had not removed the CD3217 chips off of, tried replacing with both boards, making sure to match each one to the side it came off of, and no luck. PP1V8_UPC_XA_LDO_CORE on C3105 reads 0.503 and PP3V3_UPC_XA_LDO on C3108 reads 0.492 with similar readings on C3208 and C3205 for the matching line names.

        EDIT: These reading are using diode more.

          If I am understanding correctly, then I think the issue may be something else since I can get it to boot, just stuck at 5v

          If I could just get the port to work for HDMI out and data transfer, I would be satisfied with that.
