Schematic for Compal LA-2771 at revision R0.8, a pre-release revision of the board, stored in a RAR archive of about 1.00 MB. Because it predates the R1.0 release, some components or nets may differ from shipping boards, so check the revision silkscreen first. No laptop model or brand appears in the name. Once it is extracted, the PDF lets you trace supply rails, follow the power sequencing signals, identify parts by reference designator and locate useful measurement points when diagnosing no-power or no-boot faults.
