[SOLVED]820-00165 battery symbol on display

[dukefawks]

PPBUS at 16V with the charger is a problem, it should NEVER go over 12.6V. This would indicate a shorted Q7130 or a bad ISL6259 or the traces to Q7130. Replace Q7130 and U7100 together as 1 may kill the other.

Replaced U7100 and Q7130 and PPBUS is now 8.5V,

Still the same issue: battery symbol on display.

Checked R5380 and R5381 both showing correct 2.0K ohms.

Use a known good battery with some charge in it and see if the charge goes up.

I connected clients battery, but was flat.
Battery symbol what on display but after a few minutes battery start to charge and MacBook turns on.
All works - issue solver.

Many thanks
