Boardview for the Compal LA-B211P motherboard, revision 1.0 as indicated by R10 in the name, packed in a small 197 KB RAR archive. Compal uses the LA-xxxxP pattern for boards it builds for brands such as Acer, Dell, Lenovo and HP. Boardview files show component placement, part references and net connections, so a technician can locate test points, follow a rail to its regulator and find which part shorts a line. Open it in a viewer such as OpenBoardView or FlexBV and match the PCB revision.
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.
