Compal schematic for mainboard LA-8863P, revision 0.3, archived as a 1.30 MB RAR, normally a PDF set of circuit diagrams. Compal is the ODM behind the LA-xxxxP numbering, and this board appears in the Samsung NP355V5C. The diagrams show power sequencing, rail voltages, signal paths and part values for diagnosing no-power, no-charge or short faults. R0.3 is an early engineering revision, so small differences against a production board are possible; compare the PCB markings before trusting values.
