Schematic for the Dell Vostro 3400 laptop, compressed as a RAR of about 1.07 MB. The name provides no ODM board number, revision or graphics variant, so check the title block inside for those details. The diagram serves for tracing power rails, locating shorted parts, identifying test points and following the power-on sequence. Extract with 7-Zip or WinRAR and open the PDF in a viewer, then compare the board code silkscreened on the PCB with the document before relying on it.
