Rev 1.0 Boardview: La-c701p
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.
Use the boardview to locate the large inductors: (3.3V) and PL303 (5V).
SATA 3.0 (HDD/ODD), USB 3.0/2.0 ports, HDMI, and eDP for panel interfacing. Technician Insights & Common Fixes
The and schematic are the most critical diagnostic assets required for repairing the Compal AHL50/ABL52 motherboard series. These components are used primarily in popular HP 15-ac series laptops . If you deal with common laptop component-level repairs—such as power failures, short circuits, or liquid damage—you will find this board lacks printed labels (silkscreen serigraphy) on the physical PCB. This layout limitation makes a software-based boardview file absolutely indispensable. 🛠 What is the La-c701p Rev 1.0 Boardview? La-c701p Rev 1.0 Boardview

Are you missing the on the coils?
Search the boardview file for (the current-sensing resistor for the main rail). Always ensure you download the specific files, as
Connect the charger. Locate the current sensing resistor (PR103) using the boardview tool. Measure the voltage. It must read a stable ~19.5V. If it reads 0V, trace backward through the schematic to the input MOSFETs.
The LA-C701P is a reliable board, but like all electronics, it has its common failure points. Repair logs from various forums reveal these typical issues and how the boardview helps to solve them:

blossomed across his screen—a digital skeleton of copper traces and silicon islands.
Typically supports Intel Core 4th/5th Gen U-series processors (Soldered/BGA).
In the world of motherboard-level laptop repair, having the right schematic and boardview is akin to a captain having a map in uncharted waters. One specific, widely used board in various laptops, notably the Dell Inspiron 5558 and 5758 series, is the Compal-designed motherboard with the designation [1, 2]. This article provides a detailed guide on what the LA-C701P Rev 1.0 Go to product viewer dialog for this item.
A common repository for finding specific boardview files.
Use the boardview to find test points to probe voltage levels (3.3V, 5V, 19V) using a multimeter.
