Compal boardview for mainboard LA-K321P, archived as a 395 KB RAR file. The name states only the board number, with no laptop brand, model or revision, so identify the board by the LA-K321P marking silkscreened on the PCB. The LA- prefix is Compal's standard numbering pattern, used on notebooks it builds for brands such as Dell, Lenovo, HP and Acer. Open the extracted layout in OpenBoardView, FlexBV or a similar viewer to locate parts, follow signals, find test points and check rails during fault diagnosis.
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 @BoardSchematic. Enginerys does not host this file.
