Modern motherboards like the LAD711P use high-density, multi-layer PCBs. When soldering components identified on the top-side schematic, use a pre-heater or a high-quality hot air station. The ground planes on these boards act as massive heat sinks, making it easy to accidentally rip pads if the board isn't sufficiently heated.
Measure the resistance on all large grey inductors (coils). Low resistance on 3.3V or 5V rails usually indicates a dead PCH or a shorted decoupling capacitor.
To effectively use the LAD711P Rev 1.0 schematic, follow this diagnostic flow:
Often an ISL88739. If the laptop runs on battery but won't charge, or vice versa, this is the primary component to inspect.
