Schematic in PDF form, 11.2 MB, for motherboard LA-D562P, a board number following the Compal pattern; the name gives no laptop model or revision. Compal uses LA-xxxxP codes across many brands, so check the board itself to identify the machine. A schematic lets a technician trace power rails, follow the power-on sequence, find pull-ups and check signal paths between chips. Open it in any PDF reader and verify the number and revision printed on the PCB match before trusting component values.
