Boardview for Compal laptop motherboard LA-J261P, revision 1.0, provided in BDV format inside a RAR archive; no laptop model is named. Compal uses LA-xxxxP numbers on its boards, so the board itself confirms the match. BDV opens in boardview programs such as FlexBV, where you can click a part to highlight its nets, find test points and locate a shorted component on a rail. Check that the revision printed beside the LA number agrees before relying on placement data.
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 @pkbiosbdv. Enginerys does not host this file.
