Always ensure you download the specific files, as using a boardview from a different revision (e.g., REV 0.1 ) may result in mismatched pinouts and component locations. With the right file in hand and the correct diagnostic procedure, the Compal LA-C701P is a highly repairable platform.

A short circuit on the main power rail (Public Point). In a case documented on ChinaFix, a technician discovered that the short was not caused by a common ceramic capacitor but by a burnt chip labeled RK5GB (suspected to be a SYX196DQNC ), which was the VRAM (Video RAM) power supply chip. Using a boardview, the technician located the inductor for the 1.35V rail ( PL11 ) to bypass the circuit temporarily to confirm the fault.

Launch the software and load your unzipped LA-C701P.brd file.

: Press Ctrl + F to search for component designators directly from the schematic (e.g., "PU301", "PQ202").

RAM across two SO-DIMM slots, with a maximum capacity of 16GB. Connectivity

Motherboards are multi-layered. If a copper trace burns out inside an inner layer of the PCB, the Boardview tool highlights all pins and test points connected to that specific net, allowing you to run a jumper wire safely.

: The Super I/O (SIO) or Keyboard Controller chip. It manages power sequencing, battery status, and triggers the power-on logic.

To view the LA-C701P Rev 1.0 boardview data, you need dedicated viewer applications. The standard formats for these files are .BDV , .BRD , or .CAD .

: Maps every resistor, capacitor, and inductor by its reference designator (e.g., PL302, PC110).

: Visually inspect the board for green/white corrosion. Use the Boardview to find out where broken or eaten-away traces lead, allowing you to run jumper wires to restore connectivity. How to Open and Use the Boardview File

Locate the large power inductors (coils) for the switching outputs: (+3VALW) and PL102 (+5VALW). Measure these coils for stable 3.3V and 5.0V outputs. Phase 3: Inspecting the Embedded Controller (EC)

: Use the file to locate the DC-In jacks, the first and second input MOSFETs, and the main current-sensing resistor ( PR8 or equivalent). Check for a short circuit to ground on the main B+ (19V) power rail. 2. Missing 3.3V and 5V Always-On Power Rails
