Turn off the system power supply completely. Set your digital multimeter to continuity mode (the audio beep setting).
The Southbridge releases SLP_S3# (Suspend to RAM) and SLP_S4# signals. The Super I/O then pulls the ATX supply's PS_ON# pin low, forcing the main power supply unit to turn on full +12V, +5V, and +3.3V lines.
To study the "HIG41UATX Rev 1.1 schematic" is to engage in an act of digital archaeology. It is to look at a chart of lines and nodes and see the intention of a human mind reaching out to control the flow of electrons. It is a document that teaches us about the fragility of systems and the resilience of design. It is a reminder that even in the most mundane electronic waste, there lies a complex, delicate, and ultimately temporary architecture of thought. Supplies stable power to the CPU
