Troubleshooting CPU VCORE or VCCGT voltage rails. Conclusion
A visual mapping file (often in .brd or .bdv format) used to locate specific components like resistors and ICs on the physical PCB.
Search for +3VALW in your boardview software. It will highlight all pins connected to this rail. Find a capacitor near the KB9022Q controller that shares this network and verify that 3.3V is reaching the IC.
Load the LA-C701P_Rev1.0.bdv (or similar extension) file.
