Gigabyte GA-P31-ES3G schematic for board revision 1.0A, provided as a PDF in a 984 KB RAR archive. It shows the power circuits, clock and reset logic and the connector pinouts of this P31-chipset desktop board. A technician uses it to locate the regulators feeding the CPU and memory, check voltages at the test points and work out the standby and power-on sequence. Since 1.0A is an early revision, check the PCB marking, because later 1.0C and 1.1A boards can differ in parts and layout.
