Boardview archive labelled only with the Acer brand, a ZIP of 384 KB. The name carries no model or motherboard number, so the exact board must be identified by extracting the archive and checking the file inside against the number printed on your PCB. Boardview data shows the physical placement of parts, pins and nets, and opens in tools such as OpenBoardView or FlexBV for locating test points, tracing a shorted rail or finding a missing component. Do not rely on it until the board number matches.
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 @cynetitsolution. Enginerys does not host this file.
