ASUS GL752VW motherboard layout, revision R2.0, ASUS part number 60NB0A40-MB1800. With this boardview loaded in OpenBoardView or FlexBV you can click a pin to highlight its whole net, search parts by designator and flip between top and bottom sides when tracking down a shorted capacitor or missing voltage. It sits between the R1.1 and R2.1 versions of the same board, so check the revision silkscreen on your PCB to be sure you are using the matching file.
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_schematics. Enginerys does not host this file.
How to open a .brd file
The most common boardview extension. Several unrelated formats share it, which is why one viewer opens a .brd and another refuses it.
