Schematic for Compal board LA-8861P, a 1.58 MB PDF. The LA-xxxxP format is Compal numbering, printed on the PCB along with a revision, which is not stated in this file name, so check the title block against your board. The laptop brand and model are not given either. A technician uses this document to follow the supply rails from the DC jack, trace enable and power-good lines, locate components on a shorted net and confirm connector pinouts during repair. Any PDF viewer opens it, and searching net names helps.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
