PDF schematic for a G31M-ES2L motherboard at revision 1.11. The name matches Gigabyte's G31M-ES2L, an Intel G31 micro-ATX board for LGA775 CPUs. It gives the full circuit for the CPU power stage, memory voltage, chipset rails, onboard graphics output and BIOS chip wiring. Repair technicians use it to trace rails, locate shorted capacitors or MOSFETs and understand the power-on sequence. Confirm the revision silkscreened on the PCB is 1.11, as other G31M-ES2L revisions have different layouts.
