Schematic in PDF form for the L-IQ45 / MTQ45MK-LE motherboard, with revision markings R10 and 10a in the name, packed in a 1.06 MB RAR archive. The Q45 naming points to an Intel Q45 based desktop board, although the name does not state the brand. A circuit diagram like this lets a technician follow power sequencing, VRM circuits, clock and reset signals, and identify component values. Any PDF reader opens it. Check that the revision printed on the PCB matches, because part values and layout can change between revisions.
