ASUS GL752VW laptop mainboard boardview for revision 2.0, packed in a 206 KB RAR archive. The layout lets you click a component to see its nets and connected pins, which helps with tracing the charger, standby and CPU or GPU power rails, finding a shorted capacitor and locating test points on both sides of the board. Extract it and open with a boardview viewer like OpenBoardView or FlexBV. Check that the mainboard is marked revision 2.0, since another revision can place components differently or use other designators.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
