The main system rail (19V or battery voltage) that feeds all other regulators.
If a short is found on DCBATOUT, use a DC power supply to inject 1V and use thermal imaging or isopropyl alcohol to find the heating component. Schematic Symbols and Layout Navigation
Located near the DC-in jack on the top side. If these short, the laptop will not draw any current from the adapter. lad711p rev 10 schematic top
When working on a LAD711P Rev 1.0 board, focusing on the top-side schematic and layout is critical because it houses the primary power rails and the CPU/PCH complex. Understanding the LAD711P Power Rail Hierarchy
The most common reason for consulting the LAD711P schematic is a "No Power" or "No Post" condition. The top-level power distribution usually follows this path: The main system rail (19V or battery voltage)
Look for liquid damage or burnt caps near the CPU coils on the top side.
The Rev 1.0 schematic typically includes a "Component Map" or "Board View" reference. On the LAD711P: Integrated circuits (Controllers, Gates). Q Series: MOSFETs and Transistors. If these short, the laptop will not draw
Essential for DDR4 memory and the PCH logic.
