Hey, I got really sick so sorry for the late reply. I did go ahead and swap out the charging port and it did resolve the issue. Not sure why, but it works now! Thanks for all of the help, I really appreciate you!... -
I will do some probing around today or tomorrow, once I am done with everything that came in over the weekend while I was off work. I will let you know if I find anything else....Leave a comment:

Thank you for your help btw, I hope I can get this good some day ha haLeave a comment:

I will order and replace the DC-IN jack and we can go from there. I think that is the best case scenario...Leave a comment:

Sorry about that, I added it into the edit afterward, I normally work in diode mode, so that is what I defaulted to.
No voltage at all. I can send a picture to confirm if you would like....Leave a comment:

Both sides are reading 1.715 in diode mode, no voltage on either side. It is plugged in and can verify 20v at barrel jack.
Yes, known good. I have two chargers that both work on my laptop.
EDIT: Test points start at 4.7Mohms and drop down to 0, and then the process resets.
The R005 resistor below the leftmost mosfet does have continuity from side to side....Leave a comment:

All are showing 0v, everyone other than 3 is showing OL in diode mode....Leave a comment:

Not super strong with reading schematics, I get lost pretty quickly....Leave a comment:

Asus G712L laptop does not charge, does turn on with battery.
I have a laptop that does not charge, but will turn on, so I believe this is in the charging circuit. I see not heat under thermal camera so no obvious shorts that are easily detectable from that. I am not too familiar with schematics and how to read them.
I know it is taking 20v in at the barrel jack connector, but since I am not familiar with this motherboard, not too sure how to follow power rails to nail down the problem.
Sorry I cannot provide more info, but I can answer questions if you have any.
Board: G532LWS Rev 1.3

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....Leave a comment:

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....Leave a comment:

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 -
Replaced the glass IC on a Series X, Pin 13 in now OL.
Hello!
I am replacing the booster IC (glass IC on the other side of the HDMI port) and I had to use a bypass chip I from Sourcely. I got everything set up and resolved the issue I was having from that (different line was OL) but now I am contending with this one. Is there something I can do to restore the signal?
Attached is a photo with the pad in question that is supposed to supply the signal to pin 13 on the HDMI port. Tweezers where I am pointing to.

No response from Apple Configurator on a different Macbook when trying to put it into DFU more or trying to start it normally.Leave a comment:

It charges at the rates above but will not power on.
I will let you know when I have all the info to provide back to you.
I am assuming check voltage with battery installed?Leave a comment:
-
So before I did that, I rechecked it since the last post told me to disconnect the battery, and when I took it at 12v, there was no battery attached. I re-did the check with the battery attached, and I got 12.72 on one side, and 12.73 on the other. Should I proceed with the recommended steps above or look somewhere else due to the change in reading with the battery attached?...Leave a comment:

12V on both sides of F5200Leave a comment:

It sits around here, the lowest is .3a with a one-time high of .601a.
EDIT: This is using a 140w Apple adapter with a 240w USB-C to USB-C cable.

General question about MacBook power rails for repair.
I am looking at an A2337 and found this for the order of power rails and what they do. Can this be confirmed before I dive into hunting down power rails that do not exist or are not neccisary?- PPBUS_G3H (12.6V-12.8V)
- This is the main power rail that supplies power to the entire system. Check this rail first, as it must be present for other power rails to work.
- PP3V42_G3H (3.42V)
- This power rail is derived from PPBUS_G3H and is used to power the SMC (System Management Controller) and other essential circuits. It should be present if PPBUS_G3H is working correctly.
- PPVRTC_G3H (3.3V)
- This
- PPBUS_G3H (12.6V-12.8V)
