Service archive for the Dell N4020 notebook mainboard marked DJ1, with the date-style code 100224 in the name, possibly a release stamp. DJ1 is a Wistron project designation, so this is most likely the Wistron schematic for the board. Engineers use it to trace power rails, check the charger and power-on sequence and locate components or test points around a fault. Make sure the board label on the PCB matches DJ1 and its revision before relying on the drawings. The archive is 1.12 MB and opens with 7-Zip or WinRAR.
