| Fault Symptom | Likely Area | Boardview Use |
|---------------|-------------|----------------|
| No power, no LED | DC-in circuit (PQ301, PU301) | Locate ISL6255 (BQ24737) and surrounding MOSFETs (PQ301, PQ302). |
| Powers on but no display | LCD connector (JLVDS1) or backlight circuit | Find JLVDS1, check LCD_VDD, LCD_BACKLIGHT, DISP_ON nets. |
| Short on +3VALW or +5VALW | Capacitors or ICs (PU201 = RT8223P) | Highlight net, check all caps visually for cracks, use thermal camera. |
| No WiFi / Bluetooth | Mini-PCIe slot (J9) | Check +3VALW, WLAN_RST#, CLKREQ# at slot pins. |
| Random shutdowns | Overheating or corroded EC | Locate IT8586E (EC) and check ACIN, LID_SW#, PROCHOT# nets. |
