Most boardviews default to a top-down view. Use the software’s rotation tool to match the physical board in front of you. Look for a known mark (e.g., a screw hole or the RAM slot) to align your perspective.
The LA-C701P uses the ubiquitous Texas Instruments charger IC. The common failure here is a blown high-side MOSFET or a dead AC detect pin.

For a technician, the revision number is critical. If you use the file for "La-c701p Rev 2.0" on a "Rev 1.0" board, you risk misidentifying components. The coordinates (X, Y) for a specific MOSFET or coil might be slightly different, or the component designation (e.g., R123 vs. R125) might have changed. Accuracy in file selection prevents costly errors during soldering or probing.
These machines typically feature 7th or 8th Gen Intel Core processors (Kaby Lake) and NVIDIA GTX 1050/1050Ti discrete graphics. The LA-C701P uses the ubiquitous Texas Instruments charger
The tech opens the boardview software (like Allegro or OpenBoardView) to trace the main power input. They quickly locate the first and second MOSFETs. Using a multimeter, they confirm 19V is passing through to the main rail.
Without the boardview, you would waste 20 minutes tracing a multimeter across the board. With it, you locate the faulty resistor in 30 seconds.
