Hi all,
Just one of the ports on my Macbook just died whilst flashing an Arduino.
There is no 5V usb power out of the port when plugging in a peripheral, and the computer will not charge through the port either. The other 3x USB-C ports all behave normally when supplied with power, or when delivering power.
Another thing of note is that every now and then, the computer will spit a warning that one of the USB ports is drawing too much power, even with nothing plugged in.
I've got a copy of the schematics for this board. From what I can see, both U3200 and U3100 are fed with 5V for peripherals from the PP5V_S4_X_USBC bus. I'm guessing that through some sort of internal MOSFET switching in the U3100 and U3200, this is put out to the USB port?
Assuming the above is correct, the PP5V_S4_X_USBC 5v bus is fine - given the other port works fine.
Given that it's just one port that has been knocked out, should I change the CD3215C00 associated with it?
I gather that all the CD3215 chips must be operating for the computer to charge through any of the USB-C ports.
I've got a descent binocular microscope at home, along with a really good iron (HAKKO, with micropencil), and Quick 861DW hot air station - I usually use this kit for SMD circuit development and design, but never thought I would be doing surgery on my macbook.
I've just ordered some CD3215C00 chips and a reballing stencil off aliexpress.
Can anyone tell me if the XA(U3100) or the XB(U3200) port is the port on the LH side of the computer, closest to the screen?
Cheers for your help and advice,
Bevan
