Schematic in PDF form for the Dell 5470 laptop based on Quanta board DAJW8CMB8E1, packed as a 1.42 MB RAR. Quanta labels its boards with a DA prefix and project code, here JW8, with trailing characters marking the revision. The schematic lets a technician follow power rails from the charger input through the system regulators, check enable and power-good signals and find the values of components around a shorted rail. Open it with any PDF reader and verify that the board number on the PCB matches before using it.
