PDF schematic for the Compal LA-K281P board, project GH4FT, revision 1A (1.0), wrapped in a RAR archive. It documents the power rail tree, sequencing signals, EC connections and connector pinouts, which are needed for tracing no-power, charging or boot faults. Paired with the matching boardview, it lets a technician go from a net name to the physical part on the board. Compal's LA-xxxxP numbering identifies the ODM board, so check the number and revision on the PCB before relying on component values.
