Schematic in PDF form for the sub-boards of Compal mainboard LA-G881P, archived as a 3.92 MB RAR. LA-xxxxP is the Compal numbering pattern. The name does not give the laptop brand or model. Sub-board schematics typically cover the small daughter boards such as the power button, USB, audio or card reader modules connected to the main PCB. They help when tracing a fault on a port or button through its connector. Open the extracted PDF in any reader, and check that the board numbers on your parts match.
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 @schematicslaptop. Enginerys does not host this file.
