Arrived with no liquid damage. Has a strange charging issue where it will run off a/c and charge battery the first few minutes its running but afterwards it will either stop charging the battery and run off a/c adapter for a few minutes or stop charging the battery plus act like a/c adapter is not plugged in and only run off of battery. USB amp meter shows 20V at 0 amps when this occurs.

Battery shows normal condition 180 cycles.

Any ideas on this one?

Be sure no corrosion around U7000.
Pay atention to R7020-22, R7060-62 and their traces.
Also clean battery cable and connector.
