Schematic in PDF form, compressed as RAR, for Compal board LA-K281P, platform code GH4FT, revision 1A, also marked 1.0. Compal uses the LA-xxxxP pattern for boards it builds for various laptop brands. The diagrams let a technician follow power rails from the charger input, check sequencing signals and identify components around a short. Open the PDF in any reader, ideally alongside a boardview, and confirm the revision printed on the PCB before relying on part values.
