Ok, got this mb - it does power up but does not post.
I thought this was the perfect time for me to measure and understanding the vrm circuit.
I did read the guide for vrm testing written by AK0R but did not understand everything.
There are two rows of voltage regulators, the inner row is 5525L and the outer row is 9025L.
Here are my voltages with mb on, I used gnd in the p8 plug on all of these.
Outer row towards back of mb.
Drain - 12.01V (mounting base)
Source - 1.27 V (pin 1,2 and 3)
Gate - 2.31 V
Inner row towards back of mb.
Drain - 1.27V (mounting base)
Source - 0V (pin 1,2 and 3)
Gate - 10.47V
Outer row top of mb
Drain - 12.01V (mounting base)
Source - 1.26 V (pin 1,2 and 3)
Gate - fluctuate between 1.289 to 1.296V
Inner row top of mb
Drain - 1.26 V (mounting base)
Source - 0V (pin 1,2 and 3)
Gate - fluctuate between 0.255 to 0.231V
Does this seem right or should I be worried ?
