For desktop tower hardware, the branding is usually much clearer: Look for identifiers near the PCIe slots or CPU socket. A "2021" timestamp on the board indicates the

| Symptom | Most Likely Fault | How to Diagnose with the Schematic | |---------|-------------------|-------------------------------------| | USB port not working | Broken data line trace, failed ESD diode, or cracked solder joint | Locate the USB connector pins in the schematic; measure continuity from the connector to the ribbon cable pinout using the boardview. | | No audio output | Damaged audio jack detection switch | In the schematic, find the audio jack detection pin (often labeled “JD” or “MIC_DETECT”); measure whether the switch closes when a plug is inserted. | | Whole I/O board dead (no USB, no audio) | Missing +5V or +3.3V supply from the motherboard | Check the ribbon cable for correct voltages; the schematic will list which pins carry VBUS and +3.3V. | | Intermittent connection | Loose ribbon cable or worn‑out connector | Inspect the cable contacts; the boardview helps you locate the exact pin positions to measure. | | | No audio output | Damaged audio
