Schematic labelled A102D, stored in a 2.82 MB RAR; the name gives no brand or further board detail, so the exact device should be confirmed against the PCB markings. A circuit diagram like this is used to follow power rails from the charger and regulators to their loads, identify signal paths between chips and read component values when replacing parts. Extract it and open it in a PDF viewer. Verify the board number and revision on your PCB before relying on its part references.
