    Macbook Pro A1990 - Battery not detected after connector torn off

    Hi Gang, Im working on Macbook Pro A1990, the battery connector was torn off during friend trying to replace battery. I soldered on the connector back, and created traces. The battery does charge (according to amp meter), and does power on battery only. But the signal detect line maybe done incorrectly, and the macbook shows "X" over battery icon, and "Service Recommended" on new battery

    Can somebody point me to which of these connector pins is responsible for battery detect/data line? Pin 4 on schematic had a nub on the trace, im not sure if that is important, but I ran a jumper to the corresponding test pad

    Any help or advice much appreciated!

          MacBook A1990 26 Pin Connector
          by Strolch
          Hello, can anyone tell me where I can get this 26-pin FPC connector? What is the connector for?So that one's also for the Touch Bar. I thought only the FPC at the top was for the Touch Bar. But where can I get it? I can't find the connector online. I only found the 22nd pin. Thank you....

          MacBook Pro 2018 - A1990 Dead - not charging - only 5V
          by robka
          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...

          Macbook Pro A1990 - 820-01041 Stuck at 5V / 0.02A
          by DATATECH85
          Hello,
          I am currently working on a Macbook Pro A1990 (motherboard 820-01041) which is not charging.
          The Macbook consumes 5V and 0.019A at USB-C. There seems to be a partial short-circuit on the PPBUS_G3H rail as I have 0V on this rail.

          I've physically separated (by removing F7000 and F7001) PPBUS_G3H and the ISL9240 charging chip to see which side the short is coming from. Removing these fuses gives me 12.6V at the output of the ISL chip (PPVBAT_G3H_CHGR_REG).
          However, I can't work out exactly why I don't have the PPBUS_G3H rail.

          Here are the values...
