Find a capacitor (e.g., PC102) on the schematic, then search for PC102 on the boardview to find its exact physical location.
If the main power rails are intact, a technician would then check other critical areas using information from the schematic.
Remember the golden rules of motherboard repair:
Searching the internet directly with the keyword "" will likely lead you to the forums mentioned above. However, here are other avenues to explore:
