Got this board that had been repaired somewhere. With battery connected machine sometimes starting, other not. CHecked PPBUS and it's about 6,2V. If I unplug the battery it became normal value 8,6V.
My question is: Can bad battery be cause of this kind of issue?
And what voltage do you expect with battery connected?
PPBUS_G3H automatically drops, when battery is charging.
It will slowly increase, until battery is fully charged; then switch back to 8.6V and green light too.
