Schematic for the Dell Latitude 3301 on the WASP13CS design, Wistron board 18769-1, revision A00, delivered as PDF inside a RAR of about 3.4 MB. The same 18769-1 board also appears with Vostro and Inspiron 5390 firmware here. Wistron, a regular Dell ODM, numbers its boards this way. Use the schematic to trace power rails, check sequencing and identify component values while diagnosing no-power or no-boot faults. Confirm the board number and revision on the PCB first before relying on the diagrams.
