PDF schematic for the Gigabyte GA-MA785GMT-UD2H, revision R1.3A, with a 0226 suffix that likely represents a drawing date or internal build tag, packaged in a 972 KB RAR. The board is an AMD 785G chipset micro-ATX design for AM3 and AM2+ processors. Opening it in a PDF reader lets a technician trace the standby supply, memory voltage, CPU core regulator and front panel signals during fault finding. Check the revision label on the board, as revision 1.3A differs from the 1.x and 3.x drawings for this model.
