Well the good news is that it was Q7900 that was shorted and not Q8060. Maybe the CPU survived.
I checked all the CPU power rails resistance against my two answer keys "working boards" and they were similar.
After replacing Q7900 I now have PPBUS_G3H back.
However I am missing my P5S4_EN at U7650
Once I get into U7800 I am pretty much lost.
This is not a water damaged board. Initial failure was Q7900 so I am guessing I have a PCH problem here!
PMIC_SHUTDOWN_L 3.3v
PP3V1 _RTC 3.1V
SMC_LRESET_L 0.0v
PM_SYSRST_L 3.3v
S5_PWRGD 3.2v
I am really kind of lost here.
RTC_RESET_L 3.1v
SYSCLK_CLK32_PCH "nice square wave"
PCH_SUSACK_L 3.2
yea... I am lost
