Schematic diagram in PDF for the ECS H55H-I desktop motherboard, revision 1.0A as given in the name. The H55H-I designation points to an Intel H55 chipset mini-ITX style board, and the document lets a technician follow the VRM, standby and memory power rails, trace front-panel and USB signals, and find the parts around a short. Any PDF reader opens it and text search helps locate reference designators. Confirm that the revision silkscreened on the PCB reads 1.0A before trusting component values or net names.
