Hey guys. I have a Macbook Pro A1707 that indicates charging even with no power supply connected. The Macbook is working normally except for the wrong battery charging indicator. Where in the schematic diagram should I start looking for anomalies? Thanks in advance.

What do you see for the details of your battery?

Battery Cycle count is 346 and normal condition. Logic board 820-00928-A. I swapped with a known good Logic board and it charged normally.Comment

Try a SMC reset.

Got a very strange one here. Got an A1707 that came in dead no power. Plugged into amp meter and get 5v and then power cycles. After removing the board from the housing, I get 5v on all 4 ports with no amp draw, but it stays at 5v. I then check all rails:
PPBUS_G3H - 2.3v - Not shorted (1.8 megaohms)
PP3V3_G3H - 3.3v
PP1V8_UPC - 1.8v
PP3V3_UPC - 3v3v
D6902 - 3.3v on pin 1 & 3
I then saw these readings and thought, classic ISL9239 issue
Removed ISL and replaced with donor board. Mac powered up to 20v and drew around 300mah

Hi,
my MacBook Pro 15" 2018 Touch Bar (A1990) doesn't charge anymore. Board# 820-01041-A
I'm not experienced in diagnostics, but I want to try to solve the problem with your help, because every local shop charges around 600€ (650 usd). Which is the value of the whole Macbook.
The Macbook was charging when suddenly the "charging sound" appeared every other second for around 4-5 times.
After that the Macbook was dead. It isn't charging anymore.
The USB-C Port where the charger was plugged is burned. Also The Cable and the... -

I returned home from college. My MacBook battery was flat. Plugged it in. Nothing. Won’t boot. Waited for an hour. Nothing.
When plugging the charger : 20v at 0.02 amps.
pressing any key will make the « low battery » icon show up. Then switch to 5v and 420mA constant. Trackpad clicks, keyboard works.
Decided to put the board into another M1 body with a charged battery, it’s booting perfect, still 5v and 420mA tho, and battery is not charging.
I diode moded every pin of U5200 and they’re all fine. I know very little about Apple silicon machines... -
For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.
