Schematic in PDF form for the Gigabyte GA-H61M-DS2 desktop motherboard, revision 4.01, with an AFS prefix in the name that is not explained. A 1.10 MB diagram set like this helps trace the standby and main power rails, check the power-on sequence, and identify parts around the CPU VRM, chipset and memory slots. Open it in any PDF viewer. Gigabyte prints the revision on the PCB, often near the expansion slots, so confirm it reads 4.01 before relying on values or part references.
