Boardview for the ASUS GL552JX gaming laptop mainboard, delivered as a 234 KB ZIP archive. The name gives only the model, so check the board revision printed on the PCB, since ASUS revisions can differ in component placement. A boardview opened in OpenBoardView, FlexBV or a similar program shows where each component sits, lets you highlight a net across the board, locate test points and find all capacitors on a rail suspected to be shorted, which speeds up diagnosis considerably.
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.
