PDF schematic for the Gigabyte GA-78LMT-S2P at revision 3.12, archived as a 796 KB RAR. The pages show the board circuitry, including the CPU and memory power stages, the chipset supplies, the Super I/O and the front-panel power-on logic. That makes it useful for tracing a no-power fault, checking rail voltages against expected values or identifying a shorted MOSFET. Since this model exists in several revisions, confirm that the PCB reads rev 3.12 so component designators and values match.
