Hi , not finished yet, just keeping a log. If I am reading right the output voltages from page 71 PP1v8_S0 - pulses PP1V2_S3_ENET_INTREG - pulses PP1V05_SUS - a nice and good 1.06v steady PP1V05_S0_PCH_VCCSADPLL - pulses PP1V5_S0 - Pulses From Page 72 PP3V3_S4 - solid 3.33v PP3V3_S3 - pulses...

This is the screen, a trophy in my work space.

r7402 is 90.8k ohm, checked it 3 times to be sure. Vcore is not pulsing, at least at the few multiple points I have tested at. Vcore at c1682, c1680 and c1683 no pulse at all. I also checked r7510 pin 1 for good measure (not necessarily in that order). Note: I'll have to learn how to read...

Hi, you were right @2informaticos . My initial measure of PPVCCSA_S0_CPU was a regular spike with the fan, with my crappy multimeter was reading a 1.5vish spike with the fan. Diode mode to ground on L7100 gives me 0.016 Caveat; I need better optics, I have a magnifying glass with a light...
