Boardview for the Lenovo B50-45 laptop, a Compal board with project code ZAWBB and number LA-B291P, in .bdv format. Compal uses the LA-xxxxP naming for its notebook mainboards, with the Z-prefixed project code alongside. BDV files open in boardview tools that support this format and show part placement, nets and test points for chasing shorts, missing rails or dead charging circuits. Confirm the LA-B291P marking on the PCB before relying on it, since other Lenovo models share similar layouts.
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 @boardviews. Enginerys does not host this file.
