Hi everyone.
I have this plaque, liquid drop. Coffee.
The machine has 20V and consumption of 500ma.
I have ALL_SYS_PWRGD
I have CPU voltages
I am missing PPVCCEDRAM_S0_CPU.
This voltage comes out of U7710, the activation PVCCEDRAMS0_EN_FILT_BUF
I'm missing, it comes from U7712.
U7712 would like to know how this circuit works?
I understand through the PDF that it is activated by PVCCEDRAMS0_EN_R, it comes from R7758 and it comes out of U7711.
U7711 has PP3v3_S5, has ALL_SYS_PWRGD_R, but does not have PM_OPC_ZVM_L.
How should I interpret this problem?
I already restored the system, it gave me error 9.
Error 9, disconnect coils from the CPU and restore without problem. I understand that I have the problem in DDR or CPU.
