Schematic for the Gigabyte GA-H61M-USB3H motherboard, revision 1.01 per the name, provided as a PDF in a 670 KB RAR archive. It covers this Intel H61 Sandy and Ivy Bridge era board and lets a technician follow the 5V and 3.3V standby rails, VCORE and DDR3 supplies, and the power-on signals from the Super I/O. Extract it and open it in any PDF reader. Revision 1.01 should match the label printed on the PCB, because earlier or later versions may use different components.
