    I have a a1278 water damaged board, which doesn't turn on. Supposedly, there was a buzzing sound and the computer died.

    It has good G3Hot power from both power supply and battery. The SMC is slightly warm with battery and/or PS connected. Looking at some macbook schematic, there's ALL_SYS_PWRGD signal going to pin 12 of the SMC. I'd like to measure it.

    Is there a documentation of test points on the logic board I could use ?
