Schematic in PDF form, about 1.38 MB, for the Compal LA-4901P motherboard, which the name associates with the HP EliteBook 8440, 8440w and 8440p. Compal uses the LA-xxxxP format for its laptop boards, so confirm the number silk-screened on the PCB, plus its revision, before relying on the drawings. Use it to trace power rails, follow the startup sequence, find components on a short circuit and locate test points, opening it in any PDF viewer with text search by net name or reference designator.
