ok client came in, charger is charging as usual. However I am testing to see if it charges via USB C. The computer will not charge via USB C cable which is telling me there is something still going on. I am getting 20Volts 0 amps on all 3 usb c ports. no charge icon whatsoever, but it does read peripherals. Any idea what this could be before I take this board out YET again lol

Just repaired a liquid damage A2337 M1 unit that Apple said to 'toss it away'. Could not charge and was able to negotiate 20v but at very low current. The issue was that the battery was locked out. A fresh known good battery repaired the charging fault. Consider to source a known good battery and test again.Comment

That is odd though, it charges fine on that MagSafe charger without issue? And when I plug into the usb c it doesn't even try to charge or give any noise that its trying to charge? Could that be an issue still? Replaced with a new battery we have same issue. No charge icon coming up when charged plugged in, but charges with MAGSAFELast edited by Stephen; 03-04-2025, 11:36 AM.sigpic

Bump. Any suggestions would be greatly appreciated. I may deep dive into it later today but I feel this has something to do with those crap chips on the board.sigpic

I bought a Vostro 3400 motherboard (LA-K033P) to upgrade over my damaged Inspiron 5593 (LA-J091P) board. Everything else is ok except for the battery. This battery I am using now is already a replacement one since I disposed of the bloated original one. Back in the Inspiron 5593 motherboard, the battery charges fine and is identified just fine. However, with the upgraded motherboard, suddenly the replacement battery is labeled as "Not a dell battery". When I borrow a similar battery from my colleague (which did not have replacements yet), it is identified and charges just fine.

Hi
Acer A515-43
LA-H801P
Fail: Does not charge battery, has low voltaje on connector.
Laptop didn't want to turn on, only charge led blinked.
I found PQB5 (mosfet high battery charger) in short, voltaje in +12.6V_BATT was 19 v ...
I changed it, changed PQB6 too and now battery charger voltage is 4.4V but battery is 3 cell, 11.25v, then is very low to charging.
Laptop turns on without battery and works fine, but with battery turns on and turns off inmediately, I suspect battery bad but I don't know... -
Hello All,
I have a unusual problem with a MacBook Air 2014 820-3437 that it will not charge the battery. I have 2 batteries that charge just fine in another 820-3437 so i assume that the batteries themselves are OK. One was new in 2020.
This board started off as a PP3v3_S5 short that was resolved (shorted capacitor) and came to life fine. While testing the computer I noticed that the battery was not charging so I checked the following components:
Current sensing:
R7121 10 ohm
R7122 10 ohm
R7151 2.2 ohm
R7152 0 ohm

Hello, I have a MacBook Air M1 that got water on it and now the computer does not charge the battery. The USB C port does work since I can connect the computer to HDMI for example. The battery also works well since if I connect a motherboard from another MacBook Air M1, the battery charges.
Anyone know what can it be?06-18-2024, 11:28 AM -
Hello all,
I bought a Macbook Pro 16" M1 Pro, A2485, 820-02100, which working flawlessly but not charging. I thought battery needs to be replaced but then started reading and it seems that problem will be in motherboard.
Battery sign has cross sign and MacOS can't read battery stats. Fans are full speed but can be set down via Fancontrol software.
I did start digging into in and found out below:
Diode mode:
SMBUS_BATT_SCL: 0.529
SMBUS_BATT_SDA: 0
SMBUS_BATT_SCL: 1.795V
SMBUS_BATT_SDA: 0.948V
Can anyone help...
