Without a circuit diagram, you can trace the power-on logic using standard step-by-step validation:
Check the CPU VCore on the output inductors next to the CPU socket. If you read 0V here while the fans spin, the PWM controller is missing its enable signal, or a MOSFET has shorted to ground. 3. Continuous Boot Looping
to handle almost any build or repair task. Note that "N15235" is a certification mark found on many Foxconn boards; the most common model with this mark is the Foxconn G31MXP Core Technical Specifications
The VRM controller waits for this, then activates and stabilizes the CPU VCore voltage.
Contrary to popular belief, this is not a specific product name. N15235 is Foxconn's ACA (Australian Communications Authority) supplier code number. This code simply certifies that the electronic product meets Australian market standards.
The Super I/O processes this pulse and routes a signal (PWRBTN#) to the Southbridge/PCH.
The physical power switch sends a high-to-low-to-high pulse to the Super I/O chip (often an IT8721F, Fintek, or Winbond IC on Foxconn boards).
Turn on the PC and press Tab or Pause/Break during POST to see the true manufacturer name.
While a full circuit diagram is rarely published, you can find the (pinout positions) in user manuals. Understanding the Motherboard Layout
Measure the Purple wire on your 24-pin ATX connector. It must read exactly +5VSB (5V Standby) . If missing, the power supply unit (PSU) is dead.
