so follow this chart for power up sequence https://logi.wiki/index.php/Bootup_Signal_Order i'm getting stuck at CPU VR Ready that's why i'm missing LPC_PWRDWN_L. but i can't find CPU_VR_READY in the schematics.
so.. weird thing happened, system was running, fan spinning, as soon as i put my probe on R8430, it shuts down and reboot. this is repeatable, and no i did not short something out.
i leave my probe on the point, system starts up. shows me 3v3v. remove and probe again, shuts down
Yeah, difficult to understand a post, when is written in such manner.
I now suppose that you've meant to say the board reboots when you touch PM_PGOOD_FET_P1V35_S0 line with multimeter probe.
Has R8430 correct 22K value?
Do you get PVDDQ_S0_FET?
i'm getting 1.34V on PVDDQ_S0_FET.
the board reboots not only when i touch PM_PGOOD_FET_P1V35_S0 line, it also happens when i touch R8535 pin2/PM_EN_REG_CPUVCC_S0 side as well
Replaced another PCH. i have good news! i have PLT_RESET_L and my CPU Vcore is 1.76V
CPU Heats up so i know its running.
BUT! i now do not have GPU_GOOD. no chime no display no light on LED0303.
only lights on at LED0302 and LED0301
Sorry man this is taking so long. i appreciate your assistance here
