La-c701p Rev 1.0 Boardview !!link!! Today

The LA-C701P Rev 1.0 (AHL50/ABL52) is a motherboard commonly used in HP 15-AC series laptops. It features an Intel Broadwell ULV processor and supports DDR3L RAM.

1. The Charging IC Area (PU4000 series): The Rev 1.0 board is prone to blown high-side MOSFETs near the battery charging circuit. The boardview helps you trace the BQ24737 IC pins to the associated inductors and sense resistors.
2. CPU Phase Doublers: Located near the CPU socket, these small ICs (often 95939 or similar) fail frequently. Use the boardview to check the VR_ON enable pin and phase timing resistors.
3. Corrosion near CMOS Battery: Rev 1.0 boards have a design flaw where the CMOS battery holder is close to a high-current inductor. Leakage kills the RTCRST# line. The boardview allows you to find the exact diode and resistor to patch the line.

1. Introduction

The La-C701p is a mobile motherboard platform utilizing the Intel Skylake/Kaby Lake architecture. As a mainstream laptop motherboard, it balances performance and power efficiency, featuring support for 6th and 7th Generation Intel Core processors (BGA1356 socket) and a dedicated NVIDIA GeForce 940MX GPU.
