Good morning, this mac had 1V on the PPBUS, I checked the u7100 terminals 27/28 had high resistance, then I changed the resistors and the u7100, the PPbus is now 12.56V, but the mac won't turn on.
Voltage:
PPBUS 12,56V
PP3V42_G3h 3,39V
PLT_RST_L 0,021V
PM_SYSRST_L 0V;
PM_PCH_PWROK 0V, pulse 100mV
PM_PCH_SYS_PWROK 0V, no pulse.
