These were measured between far side of the resistor RF295, RF296, RF297, RF298 and corresponding pins of UF260.
That was done in resistance mode, no power to the board.
Next thing I measured the voltage drop to ground with USB-C plugged in and cycling 5V....Last edited by astyrcz; 11-16-2024, 11:28 AM. Reason: I want to provide as much information as possible.

820-02020 board. 5V cycling on both ports
Hi! I'm having very similar problem with 820-02020 board. 5V cycling on both ports, the rear one, closer to UF400 0.11A - 0.28A and resetting meter, the front one constant 0.24A resetting meter in faster cycle. I have replaced already both CD3217 and this behavior changed a little - previously the front port had also changing current draw and slightly longer reset cycle.
These weren't chips pulled by me from another board. I got them on Ali 5pcs. Tried 4 of them, same effect.
The computer was bought as not working with info that worked on battery till it drained. Did not charge it...
