Lad711p Rev 10 Schematic Top (HIGH-QUALITY — COLLECTION)

Based on community discussions on Vinafix and other forums, some specific components are common points of failure on this board:

One user on Badcaps.net reported that their LA-D711P was not charging, even with a new battery. The schematic was used to investigate the battery management system (BMS) communication. Here’s how it helps:

: The areas near the touchpad connector and the audio jack are highly susceptible to trace oxidation if liquids spill onto the laptop keyboard.

Check the entry point through the DC-IN jack. Verify the first and second MOSFETs (often part of the B+ circuit) for 19V delivery. lad711p rev 10 schematic top

The center of the board is occupied by the AMD APU, which combines the CPU and GPU. This is usually the BGA component, requiring precise heat management. 2.2. Power Management IC (PMIC)

The keyword also specifies "schematic top." This most likely refers to the "Top Layer" (or "Component Side") of the printed circuit board.

The revision number indicates the version of the schematic. Revisions are made to correct errors, improve performance, or redesign the circuit. Based on community discussions on Vinafix and other

Integrated AMD Radeon R5/R7 or discrete variants depending on the specific model. Where to Find the Files

The "Top Layer" is the side of the PCB where the vast majority of components are physically mounted. A top-layer schematic or boardview shows components from this perspective and is crucial for physical component identification, repair, and soldering. In boardview software (commonly using .FZ , .BRD , or .CAD files), you can toggle visibility for different layers. It's essential to combine the schematic diagrams (for electrical connections) with a boardview file (for physical layout).

: Measure resistance to ground on the +3VALW and +5VALW inductors. A reading below 10 Ohms indicates a dead short, often caused by a failed ceramic capacitor, a blown Super I/O chip, or a shorted internal processor rail. Check the entry point through the DC-IN jack

When you open the , you should see a unified diagram with several distinct zones. Let's walk from left to right (input to output).

Power enters the board from either the 19.5V DC jack or the 11.1V Li-ion battery. This voltage is distributed across the board as the primary high-voltage rail, usually labeled or VIN . Two isolation MOSFETs managed by the charging IC control this entry point to protect the board from overvoltage or reverse polarity. Always-On Power Rails ( 3V_5V_ALW )

Issued directly by the EC to transition the power states, turning on the regular step-down power switch lines.

Repair technicians frequently report a specific subset of failures on this particular Compal board design:
