      Check with the original battery that was removed from the laptop. See if you can reproduce the issue with the used battery.

                  Macbook a1707 - 3 ports cycling and 1 stuck on 5v
                  by vanromic
                  Hello! I'm trying to resuscitate a Macbook that the local tech gave up on. I have the board view and schematic and have the main board out of the case.

                  Of the 4 usb-c ports, 3 cycle at 5V - they all go up to about 1.5A, then seem to switch off, back to 5V 0A, up to 1.5A, and off again. The cycle lasts a few seconds - maybe 3s.

                  The 4th port doesn't cycle and draws ~0.5A at 5V consistently. It seems it's the port linked to U3100 - it's on that side of the board and is the port closest to the battery and the CD3215C00 chips.

                  I've read that the CD3215s are...

                  Macbook Pro A1707 820-00281 Stuck @5V
                  by JasonC89
                  So I have an Macbook Pro that came in for no power (I dont do a lot og Macbook repairs). After some testing I found it was only getting 5V with very little current draw, if any.
                  I searched around for shorts, and didnt find any. No real signs of liquid damage etc.

                  Following a couple of questions from other members here I was able to further test voltages etc. Im now at a point where PP3V3_G3H is showing, but only at 2.23V.
                  I have 5v on the Enable pin.
                  Also the dual diode D6902 is showing :
                  5.19V @ Pin 1
                  0v @ Pin 2
                  4.15V @ Pin 3

                  Hey....

                  Board as written in description was stuck at VGA LED. common Problem wit these type of bords.... tried all the "standard stuff" like resettin... reseatin.... found out the LED Controller MCU1 = IT8295FN-56A geting burning hot under the last PCI Slot.. now i desoldered it cause there were only 18 ohms at the caps arround.... another aorus x470 in working condition with similar part and nearly same layout had arround 280 ohms...

                  my question is: why doesnt the board start know without this chip.... worked myself through the boardview but i can´t understand...
