Schematic diagram for the HP EliteDesk 800 G2 desktop motherboard, board code Spitfire revision A, in a 1.52 MB PDF. It documents the power supply sequence, VRM stages, the SPI flash and super I/O connections, and connector pinouts, which helps diagnose no-power, no-POST and missing-rail faults. It opens in any PDF reader and pairs well with the Spitfire BIOS images. Check that the board revision matches A before trusting component values and net names on the pages.
