Archive for Compal board LA-5893P, packed as a 967 KB RAR. The name gives only the board number, without the laptop brand, model or revision, and Compal builds boards for many brands, so the PCB marking is the reliable reference. The contents are not listed; a schematic is likely at this size. Match the board number and revision first. Then use the document to trace power rails, find test points, follow the power-on sequence and locate shorted components or failed regulators.
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 @generalschematics. Enginerys does not host this file.
