820-00928 Powers on, will run off battery, wont charge battery.

820-00928

Will run off charger alone, no battery connected, will run off battery, however when plugged into charger while on battery, it will say "Battery Is Not Charging".

I used my USB-C meter, and the board will take 20.38V and 0.000-0.020 mah while plugged into the charger, and having the battery plugged in.

There was some corrosion around U7000, however Ive replaced what needed to be replaced and still the same issue. Im struggling to find the cause because of my lack of understanding of why this is, and how the charging circuit works.

Thank you!

Check first if Q7065 isn't shorted D-S.
Next, check ohm resistance over C7020/23.
Post F7000 voltage in all cases, charger, battery and both connected.
