Boardview for Quanta board DAG3JCMBCE0, project G3JC, in a 1.58 MB RAR, a smaller variant than another package with the same name. The number uses the Quanta motherboard scheme, and the laptop brand is not stated. Extract it and load the layout in OpenBoardView, FlexBV or a similar tool to locate parts by designator, follow nets and find test points. Technicians use it while measuring a dead board alongside the schematic. Check the board code on the PCB, including the revision suffix, before trusting 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 @BoardSchematic. Enginerys does not host this file.
