4. Typical troubleshooting without full schematic

• Check 3.3V, 5V, Vcore, VCCIO power good signals.
• Verify BIOS SPI flash CS# and clock activity.
• Measure PCIe CLK and SATA activity LEDs.
• Look for a super I/O chip (e.g., ITE, Winbond) for COM/LPC debug.

• The schematic will map the specific data lines to the output connectors. If lines appear, the schematic helps identify if the issue is a specific driver IC (COF) or a broken trace on the PCB.
