Gigabyte GA-H81M-HD3 motherboard schematic for board revision 1.05, stored as a PDF in a 679 KB RAR archive. It documents the power circuitry, Super I/O, clock and reset paths and the connector pinouts, all useful when tracking down boot failures or a dead rail. A standard PDF viewer opens it. Check the revision marking on the PCB first, since later revisions of the same model may use different parts or values in the regulator and front-panel sections.
