Finding a full "component-level" schematic (showing every resistor and transistor) for these proprietary desktop boards is rare, as manufacturers typically do not release them to the public. However, technical manuals and board-level diagrams are available:

OptiPlex 7010 (LGA1155): The Dell OptiPlex 7010 Service Manual provides the system board layout, identifying all internal connectors and components.

OptiPlex 780 (LGA775): Technical information for this version includes details on the Intel Q45 chipset and support for up to 16GB of DDR3 RAM. Don't settle for a blurred photo from an image search

Schematic Repositories: Third-party databases like DeviceDB sometimes host PDF schematics for specific board versions, such as the LA0531 or LA0601. Key Hardware Specifications

Because the "E93839" label covers multiple generations, you must identify your specific model (e.g., GA0402, GA0403, or LA0601) to confirm specs:
