Boardview for the ASUS G512LI gaming notebook, revision 1.1 as given in the name, packed in a RAR archive. After extracting, the layout opens in a boardview program such as OpenBoardView, FlexBV or Boardviewer, depending on its format. It shows where each component and test point sits and which nets link them, which helps when finding a shorted rail or tracing a missing voltage. Note that a revision 2.0 schematic exists for this model, so check the revision printed on your PCB before relying on part positions.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.
