For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

Hello everyone,
OK, so here is my issue.
This Lenovo B470 motherboard I am troubleshooting died and I identified it is the discrete Nvidia graphics chip that has lost it's ways!
So I removed it and now I am trying to change this motherboard to use UMA graphics, but I am having an issue interpreting the attached diagram. I have a 10K resistor in at the R2013 position and another one at the R2012. R2010 and R2011 are empty.
The motherboard starts, the fan spins but no display. It turns off by itself. I restart it and it does start but stays on...08-12-2024, 02:01 PM -

Error description : Can not turn on power. But when forced to turn on the power ( green wire to ground ). Can turn on power and use ok.
So, I think the circuit from Sio to green wire ( atx power ) is broken.but i don't know what electronic components it goes through.
Anyone know, can you show me where that electronic component is located on the motherboard? share schematic with me please . thanks:
