page 6 shows cpu configurations 0-16 but neither page 6 or 132 show what specific cpu each 0 -16 configuration is supposed to be

Which resistors should I be looking for? This board originally came with a i9 2.4GHz CPU The donar board which I pulled the CPU from is a i7 2.6GHZ. Is it possible for this CPU to still work if some resistors were changed in this case?

What is the purpose of the donar board configuration? When the board is powered on I do not see CPU core go to 1v. It starts at 0.2v and goes up to 0.6v

The CPU is a i7 2.6GHz going on a board with 64GB ram 1TB SSD and 5500M GPU. How do you tell which resistor configuration this is based off the two pages??

When I search CPU strap nothing shows up in the schematic. Do I need to use different wording to find it or does this board not have CPU configurations strap?

CPU replaced. L7211/21/31 is now 0.300v-0.520v fans spin but still no caps lock light or screen activity. Completed DFU restore successfully. This board came with a i9 but it was replaced with a i7. Do any resistors need to be changed when changing to a different CPU?

Replaced U7100 and U4710 but no change

So in this case it’s either a bad U7100 or CPU?

CPU_VCCST_PWRGD also measures 0.16V on a good working board without battery

ALL_SYS_PWRGD and PP1V05_S3 are present. CPU_VCCST_PWRGD 0.16V

Yes board is tested alone on the desk. No damaged components. Board looks pristine

PPVIN_S0_CPUVR_VIN 12.65V PP5V_COREVR_VCC 5V CPU_VR_EN_R only 0.16v

Is there anything else you would try before replacing the CPU next in this case ?

PM_SLP_S3_L also had a partial short so replaced U1200 now have 1.8V PP1V8_S5 along with 3.3v on PM_SLP_S3_L but no changes. Performed another DFU restore. L7221 is a steady 0v from when board is powered on

PP1V8_S5 is 0v diode is 0.285 but on a good working board diode is 0.345 Should voltage be injected to find the partial short?
