La-c701p Rev 1.0 Boardview ((link)) Today

Compal LA-C701P (Rev 1.0) is a motherboard platform primarily used in the HP Pavilion 15-AC

laptop series. For technicians, finding a boardview file is essential for tracing circuits when standard schematics are unavailable for this specific model. AliExpress Core Specifications Processor Support

: Integrates Intel 4th and 5th Generation ULV processors (e.g., Core i3-5005U, i5-5200U, i7-5500U).

: Available in UMA (Integrated) or Discrete (DIS) configurations, often featuring the AMD Radeon R5 M330 with 2GB VRAM. : Supports DDR3L-1600MHz

RAM across two SO-DIMM slots, with a maximum capacity of 16GB. Connectivity La-c701p Rev 1.0 Boardview

: Includes support for SATA 3.0, USB 3.0/2.0, eDP for the display, and HDMI output. AliExpress Common Repair Issues Technicians often encounter the following faults with the No Power/Dead Board : Often linked to failures in the RTC section or missing LDO (Low Dropout) voltages. Power Rail Missing

: Common reports include the 3V rail being present while the 5V standby rail is missing, preventing the board from triggering. Low Power Load

: Cases where the board turns on but shows very low current consumption, often requiring chip-level diagnosis of the SOC/PCH sections.

How to Use the LA-C701P Rev 1.0 Boardview: A Step-by-Step Example

Let’s simulate a real-world repair: "Dell Inspiron 15 3558, power LED turns on, but no display, fan spins high." Compal LA-C701P (Rev 1

Step 1: Load the File

• Download the LA-C701P Rev 1.0 Boardview.brd (or .cad).
• Open it in OpenBoardView (free, reliable).

Step 2: Verify the Power Rails

• Use the Netlist search. Type +3.3V_SUS.
• The boardview will highlight in green all components that should have this voltage. Probe a capacitor near the PCH. If it’s 0V, you know the SUS rail is dead.

Step 3: Check the CPU Vcore

• Search for VCC_CORE.
• The boardview shows the large inductors (e.g., PL1101, PL1102). Measure voltage. If 0V, you need to check VRM_ENABLE.

Step 4: Flash the BIOS

• The no-display, high-fan issue on LA-C701P is frequently a corrupted BIOS.
• Use the boardview to locate U5 (Winbond 25Q64FVSIG).
• Note the pinout: Pin 1 (CS#), Pin 2 (SO), Pin 5 (SI), Pin 6 (CLK).
• Solder your CH341A programmer wires to these points (or desolder the chip) and flash a verified clean dump from a trusted source.

Step 5: Check PCH_RESET#

• If the BIOS is good but still no display, the PCH might not be releasing reset to the CPU.
• Search for PLT_RST# or PCH_PLTRST#. The boardview shows which resistor or test pad to probe.

Zone 1: DC-In & Charging Circuit (Near the DC Jack)

• Components: Charging MOSFETs (PQ101, PQ102), Charging IC (PU101 – likely BQ24780S), Current sense resistor (PR101).
• Common Faults: Blown high-side MOSFET, dead BQ24780S due to ESD, cracked DC jack.
• Boardview Clues: Look for the thickest copper traces coming from the DC jack. The boardview will help you trace ACDET and REGN pins of the charger IC.

3. Identify Unmarked Components

Resistors and capacitors (0402 or 0201 sizes) rarely have values printed on them. The boardview file provides the designator (e.g., PR101, PC205) which you then cross-reference with the schematic to find the specific value.

5. Common Failure Analysis (Troubleshooting using Boardview)

Using the La-C701p Rev 1.0 Boardview, technicians can identify the physical locations of the following common faults:

Introduction

In the world of laptop motherboard repair, precision is everything. Guessing which capacitor connects to which IC or blindly probing voltage rails is a fast track to disaster. For technicians working on Lenovo’s high-performance gaming and business laptops, the LA-C701P Rev 1.0 motherboard is a common yet challenging platform. Without the correct documentation, repairing shorts, missing voltages, or power cycling issues on this board is nearly impossible. How to Use the LA-C701P Rev 1

Enter the Boardview file. Specifically, the LA-C701P Rev 1.0 Boardview is the digital blueprint that transforms a chaotic green slab into a navigable city of components. This article dives deep into what this boardview is, where to find it legally, how to read it, and how to use it to diagnose and repair common faults.
