Hello,
I have a MacBook A2681 820-02536
The customer brought me the computer, which would not turn on. I found a short circuit on the C77F6 capacitor.
I removed it, then replaced the PMU U7700, and the computer started up normally, but the battery is not detected.
When I test the values of the battery slot, everything is fine, including the voltage. I have 12V on pins 10, 12, 14, 16, 26, 24, 23, 19, and 20.
On pin 13 (SDA) I have 1.8V and on pin 11 (SCL) I have 1.8V.
Then on pin 15 I have 0.130V, so the voltage is too low,
and on pin 2 I have 0V.
Can you tell me where this is coming from?
