Re: Replacing OST caps on Microstar KT6 Delta motherboard
Gosh, i really need to sharpen up, and watch out for dyslexia (which, IMO, is really not just paying enough attention)
Not sure if it happened while reading it, or during the transition to writing it down.
Or perhaps i got distracted by that buzzing noise, and it was past bed time.
Note to self : Next time you see 2_5 and get a 'reading' of something 2.15, recheck it.
Sorry 'bout that
Rechecked VSUS2_5, and it was 2.51V - not 2.15V
So looks like it's meant to be on.
The voltages at that op-amp U12 are:
Pin (3 & 5) (VREF) = 1.25V
Pin 8 (9VSB) = 9.67V
Pin 2 = 1.26V which goes to resistor R245, and other side of this resistor has 2.51V (VSUS2_5)
Does that mean that it becomes a 12V serial bus, or is it still a 9V serial bus with 12V on it?

I can see, however, that when the PC is running, that "9VSB" becomes 12V because of diode D11.
Does that mean that it becomes a 12V serial bus, or is it still a 9V serial bus with 12V on it?
