Looking for MS-16J31 Schematic or Boardview

[MJ-meo-dmt]

Having battery / Charger issues.

replaced drivers / BQ Charger / Checked senses / Coil

Suspect the selector IC or something on the Adapter Detect/AC_ok circuits?

But since I'm not sure and its been a really long time...; I would really appreciate a schematic for this MB.
