Hardware Architecture: Understanding the LA-C701P Motherboard
: If the system power button produces no response, use the boardview map to locate the 3.3V and 5V power coils. Measuring these points lets you verify if the standby chip is transforming the 19V input into the regulated voltages needed to power the system's control logic. 3. Super I/O (SIO) Controller Path
The designation indicates this is the first production revision of this specific PCB layout. Later revisions (1.1, 2.0, etc.) may have different component placements or trace routing, which is why specifying "Rev 1.0" is critical.

By identifying capacitors on the main power lines ( ), you can find the culprit of a "dead" motherboard.
The EC releases the EC_RST# signal and sends power management commands to the CPU/PCH.
The Compal LA-C701P (also known as ABL51) is a widely deployed laptop motherboard manufactured by Compal Electronics. It serves as the main logic board for several popular laptop models, most notably the Dell Inspiron 15 (3558) and Inspiron 14 (3458) series powered by Intel Broadwell processors. Super I/O (SIO) Controller Path The designation indicates
Due to copyright restrictions, we cannot host the file here. However, the LA-C701P Rev 1.0 boardview is widely available on repair forums (Badcaps, ReviveIT) and GitHub repositories dedicated to laptop schematics. Search for the exact string:
If you are working on a motherboard manufactured by Compal (a major ODM for brands like Dell, Lenovo, and HP), specifically the LA-C701P revision 1.0, you have likely hit a wall trying to find clear, actionable layout data. This article delves deep into what this boardview is, why you need it, where to find it, and how to use it to diagnose common faults like "no power," "short circuits," or "dead CPU rail."
The sound was flat and final. The capacitor was a bridge to nowhere. By identifying capacitors on the main power lines
: The full schematic consists of approximately 61 pages of engineering drawings covering power signals, signal rail configurations, and component layouts . Where to Access :
Check the LDO outputs: Pin 3 (VREG3 - 3.3V) and Pin 13 (VREG5 - 5V). VREG3 directly powers the EC chip's basic circuitry.
Ensure the filename includes "Rev 1.0" or "r1.0". If you find only "LA-C701P Rev 2.0," do not use it for a Rev 1.0 physical board.
A boardview file is a specialized CAD data document that renders a dynamic, interactive 2D visual map of a physical motherboard . While standard schematic diagrams explain abstract electrical logic using lines and symbols across multiple pages, a boardview focuses on the exact physical layout.
