Circuit diagram for the Gigabyte GA-78LMT-S2PT desktop board, R31 in the name, which points to revision 3.1. The PDF is stored inside a 764 KB RAR archive. With it a repair technician can follow the power-on chain, check voltage regulators feeding the CPU and memory, and locate the components connected to a shorted rail. Unpack it and open in any PDF reader. Make sure the board on the bench carries the same 3.1 revision, since later revisions of this model use different documentation.
