Schematic for the Gigabyte GA-78LMT-S2P, an AMD-socket micro-ATX motherboard, with the name tag R311 most likely meaning revision 3.11. It comes as a PDF inside a 611 KB RAR archive. A technician uses the diagrams to trace the CPU VRM, memory supply and standby circuitry, follow the power-on signals and locate parts near a short. The GA-78LMT-S2P had many revisions, so match the revision printed on the PCB with this document before you rely on reference numbers or values.
