Schematic diagram for the Compal LA-B511P motherboard, revision 1.0, supplied as a 1004 KB RAR archive. Compal uses the LA-xxxxP numbering on the laptop boards it builds for several brands, and the code is printed on the PCB itself. Technicians use such schematics to trace power rails, follow the power-on sequence, find what feeds a shorted line and identify component values. Unpack the archive and open the PDF in any viewer. Make sure the revision on your board matches, since component placement and values can change between revisions.
