Schematic archive for the Dell Vostro 3500 laptop, built on Wistron board 09628-1 with the project code DW50. Wistron numbers its boards in a five-digit dash-revision style, and Dell machines of this period often used such Wistron designs. Confirm the number on the PCB silkscreen before relying on component values. Unpack the RAR with WinRAR or 7-Zip, then use the diagrams to trace power rails, check the charger and EC circuits, and locate the parts behind no-power faults.
