GOOD for you!!!

For the next one. (Yes, there will be more) ;-)
Dont know what BoardView program you are using. But if you check out Paul Daniels amazing program it will help you a lot.
Even his free version is way better then tha other old shit out there.
So, if you now have a short on pp3v3_S5, ctrl+f to search that on the board. then you click on one of the highlighted points. Then you see pp3v3_S5 out to the right in the component spec. Click on that PP3V3_S5 and you will get...Leave a comment:

Yeah, DONT use to much alcohol on the board, Drink most of it

Yes, Pure Alcohol would do. I use Pure Methanol myself, but just coz i have alot of it.

Ok, Then you have to check where ALL_SYS_PWRGD is coming from (Q8150). Is that turning on. If not you follow that back and so on..
You also have to do the same for CPUVR_PGOOD_R. Both of them needs to be present for it to close and let PP3V42_G3H pass to the next step witch is out of the chip and then back in at pin 7....Leave a comment:

Re: 820-3437-B No PP3V3_S5 or PP5V_S4RS3
Just something to check.
Look closely under the U1950 on pin 1 (you might have to remove it to be sure), i have had a couple of them where everything looks good but under the chip on pin 1 its burned away and you will never get PM_S0_PGOOD.
I guess you checked for corrosion on all the probe points on those rails as well.Leave a comment:
