Dell OptiPlex 3040 schematic set in PDF form, archived as RAR, covering the small form factor build; the name lists SFF tokens and an A00 revision code. These diagrams help a technician trace power rails, inspect standby and main voltage regulators, follow signal paths and identify component values when a desktop will not start. The exact meaning of the remaining codes in the name is not certain, so compare board markings on the PCB with the drawing before taking measurements.
