Subject: Help Needed: MacBook A1278 (3115) No PPBUS_G3H Issue
Hello everyone,
I'm working on a MacBook A1278 with the 3115 logic board and facing an issue with no PPBUS_G3H voltage. Here's what I've checked so far:- U7000 Measurements:
- Pin 3 has 0V, even though R7012 shows 16.5V from PPDCIN_S5_CHGR.
- Resistors:
- I measured R7010 and R7011 with one leg disconnected, and both tested OK.
Based on these findings, I believe U7000 needs to be replaced. However, I have a related question:- If I also decide to replace the SMC, do I need to order it pre-programmed,

Hi everyone

There's also an extra OTP Secu.R... -
