BDV boardview for revision D of the Y61-MB motherboard, delivered as a 236 KB rar. The name lists only the board code and revision letter, without laptop brand or model. Open it in OpenBoardView, FlexBV or a similar viewer to look up part designators, follow nets between chips and locate test points for rail measurements. A separate E-revision file exists for this board, so confirm the revision on the PCB before trusting the layout.
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 @SCHEMATICWORLD. Enginerys does not host this file.
