[SOLVED]820-2936 - Works on DCIN, works on battery, trips the charger if both connected.

Obviously a dead short somewhere to trip the charger. Issue is that I can't work out how to track it down; not sure where to inject power.

Board had many issues, I replaced U6900, Q5310, U7000 and finally got a green light and fan spin back.

Issue now is that it trips the power adapter if the battery is connected.

Known good battery? PPBUS voltage?

You were correct, there was a shorted Q7030.

Mark solved please.
