Board-level schematic for Compal LA-4117P, revision R0.3, in a 1.16 MB RAR container. The LA prefix identifies a Compal-designed laptop motherboard, and Compal supplies boards to multiple brands, so this number is the reliable identifier. Being a pre-release R0.3 drawing, some parts or values may have changed on production units, so compare carefully. The diagrams help with diagnosing no-power faults, following always-on and switched rails, checking EC signals and finding where a short sits. Unpack with a standard RAR utility and open the PDF.
