PDF schematic of 2.13 MB titled only V6J, a model or project code with no brand, board number or revision given. Open it in a PDF viewer and read the title block to confirm which notebook and mainboard it describes before using it on a repair. Once matched to the PCB, a schematic like this lets a technician follow power rails from the adapter input, check enable and power-good signals, locate the BIOS flash and EC, and work out which components hang on a rail that reads shorted.
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 @alischematics. Enginerys does not host this file.
