Dell Vegas/Turis SKL/KBL 15341-1/91N85 missing VR_RDY

[lapfix]

Hello my friend.

When connected to power supply consumption is 0.09 amp / power button = reach 0.150 amp...than off.

i follow the power up sequence and as i know :

After getting ALL_SYS_PWRGD, the io generate a signal adressed to VRM called VR_ON / VR_EN , this is the VRM enable signal .
If CPU core is ok the VRM chip will generate its power good signal adressed to SP/PCH , this signal is termed = VRM_Power good / VR_RDY .

With this motherboard all is ok until sequence 8a= VR_RDY.

Questions :

1 = Trying another bios can solve this missing !...means at this steps maybe there 's a communication between cpu and bios !!

2 = can we confirm that PU4601 is faulty !!.

measure taken :

pl4501/4502 = 3/5valways are present

pl5301 = PWR_1D0V = 1.043v 240v is present
is present.

After power button :
pl5101 = PWR_1D2V = 1.240v is present.
pl5001 = PWR_+VCCSA = 1.044v is present .
pl4701 = VCC_CORE = 0v
pl4801= +VCCGT = 0v

Good to know you fixed it but i'm wondering why you started a thread without doing basics first. Afterall, you are not new to this forum. Hope you dont feel offended and take this as positive.
