Gigabyte GA-H61M-DS2 motherboard schematic, revision 2.01, supplied in PDF format. The H61 in the name indicates the Intel H61 chipset, used with LGA1155 processors on this micro-ATX board. Repair technicians use the diagram to follow the standby and main power rails, check the CPU VCore controller and MOSFETs, and locate the SPI BIOS chip before reprogramming it. Gigabyte released several revisions of this model with different layouts, so confirm the PCB reads 2.01 before you trust the component references.
