"VCC_CORE" refers to CPU power; "5V_STB" is the standby power from the PSU. ⚠️ Important Safety Warning Repairing a motherboard requires specialized tools: Multimeter (with fine-point probes). ESR Meter (for testing capacitors). Hot Air Station (for SMD replacement). Oscilloscope (to check clock signals/data lines). If you share with third parties, their policies apply
