Note: CPU and GPU rails naturally have very low resistance (often between 1 to 10 ohms). Do not confuse this with a dead short (0 ohms). Step 3: Voltage Injection Tracking
Click on any component pad in the software. Note how all other pins connected to that electrical network light up in yellow or red.
Liquid spills usually hit the edges or pass through the keyboard connector. Inspect the motherboard under a microscope. Use the Boardview to trace corroded, broken copper vias back to their origin to run jumper wires. 5. Software Recommendations for Opening Files
Use the Boardview to find all decoupling ceramic capacitors connected directly to the +19V_PREREG or +PWR_SRC rail. One of these ceramic capacitors is likely cracked and shorted to the ground layer. Missing 3.3V and 5V Always-On Rails
A boardview is a specialized file format that provides a digital representation of a Printed Circuit Board (PCB). It allows technicians to: Identify Components
If you identify a 0-ohm short on a critical rail, use the Boardview to select a safe injection point. Solder a thin wire to a pad on that specific net, set your DC power supply to an appropriate voltage (never exceed the rail's rated voltage!), and inject 1A–2A of current. The faulty component will rapidly heat up, making it easy to isolate and replace. Tips for Finding and Using the Dkl50 La-e802p Boardview
Motherboards often have multiple revisions (e.g., Rev 1.0, Rev 2.0). Ensure your Boardview matches the exact revision printed on your physical PCB to avoid pin misalignment.
Always use the Boardview in tandem with the LA-E802P Schematic . The schematic tells you what the voltage should be, and the boardview tells you where to put your probe. Conclusion
However, I can give you a useful and point you toward legitimate sources where you can find the boardview.
Look for the main current-sensing resistor ( PRB1 ) on the boardview.
As a fallback:
To open these files, you will typically need software such as:
The exact physical location of components (resistors, capacitors, ICs, MOSFETs). The pin numbering for ICs. The PCB traces and how components are connected. Signal names and voltages. 2. Key Features of the LA-E802P Boardview
Sometimes contain links to download schematic and boardview files.
