Hi,
I am practising with another 820-00840-A board that does not turn on.
There is no sign of liquid damage.
My charger gives 20V so I have PPBUS_G3H.
PP3V3_G3H gives me 3.41V
Then my S5 rails are all missing.
I figured that PP3V3_S5 reads 7 Ohms to ground. I suppose this means a short to ground. I know 7 Ohms could be fine for some rails such as CPU VCore, but I think this is no good for that PP3V3_S5 rail, right ?
Is there anything else I should check before I try to inject some voltage into that rail in order to find the short ?
