Hi Deniz,
Did you solve this issues?
i have the exact same issues like yours, A2780 820-02890 switch 20v but stuck 140mA
Could you give me hint, if the SoC failed then is the U0600 failed also or need re-programmed U2010?
Thanks

MBA13 M3 2024 A3113 EMC8611 820-03285 No Trackpad No Keyboard (water damaged)
Hi Guys,
This Mac come with dead issues (severe water damage), now it’s turning ON except Trackpad and Keyboard not working.
Already check and write down DM for JT400 and JT201 don’t find any abnormal value (I don’t have unit for compare).
Already try,- Replacing Trackpad Flex Cable
- Replacing New Trackpad
- Replacing Little Board (Daughter Board)
- Try using New Keyboard
So I check “Power Load Switches” and this is all the numbers,
UC830 > 1 = 3.297V ; 3 =1.757V ; 4 = 3.798V... -

Re: MBP13 2016 A1706 820-00239-A Charging BUT not detect external drive (NO 5V output
Y3000 perfect condition, no damage & soldered properly, i even replace it from donor boards to make sure.
I checked R3007 = 0ohm (correct value)
Y3000
pin 1 = 0.388v / DM 0.808
pin 3 = 0.315v / DM 0.754
L3500 & LB700 still 0v
This is just my stupid questions, what if i put/inject power (3.3v) from another sources to UPC_X_5V_EN / UPC_T_5V_EN ??Leave a comment:

Re: MBP13 2016 A1706 820-00239-A Charging BUT not detect external drive (NO 5V output
https://www.ugreen.com/products/usb-...-0-otg-adapter
I'm using this converter more than years and working properly.
I tried to different MacBook Pro (2016 13 Non TouchBar, 2017 13 TouchBar, 2017 15 TouchBar), all working perfect... just plug & detect.
But in this mac nothing happen (USB converter LED power OFF)...Leave a comment:

Re: MBP13 2016 A1706 820-00239-A Charging BUT not detect external drive (NO 5V output
I'm using simple converter from USB 3.0 to USB-C instead of external hub...Leave a comment:

MBP13 2016 A1706 820-00239-A Charging BUT not detect external drive (NO 5V output)
All 4 USB-C port have 20v, can charge, turn on fine and work properly BUT doesn't detect external drive / USB on all ports (No 5v output)
L3500 = 0V / DM = 0.332
LB700 = 0V / DM = 0.337
PP5V_S4 = 5V (R3501, R3506, RB701, RB706)
UPC_X_5V_EN = 0.198V / DM = 0.539
UPC_T_5V_EN = 0.215V / DM = 0.543
From schematic, UPC_X_5V_EN & UPC_T_5V_EN sending out from CD3215
What should i check before replacing CD3215 ??
