While a schematic shows how components are electrically connected via lines and symbols, it does not show you where those parts are physically located on the PCB.

Measure for +19V at the drain of the second MOSFET. Step 2: The Charging IC & System Rail ( +BVDD / +PWR_SRC ) la-d402p schematic

When an LA-D402P board is "dead"—showing no signs of life, no LEDs, and drawing 0.00A on a bench power supply—your troubleshooting must follow the power rails sequentially using the schematic. Step 1: The Primary Input Rail ( +19V / VIN )

Because the Spectre 13 is designed for extreme portability, its components are densely packed, leading to specific repair challenges:

Since the LA-D402P schematic is proprietary, the following diagnostic workflow is recommended:

: Features dedicated NVIDIA GPUs like the GeForce 920M (N16V-GM) or 820M (N15V-GM) with 2GB of dedicated DDR3 memory. Details the power supply to the AMD processor,

The is the official blueprint for the Compal BKE31 motherboard , which powers the ultra-thin HP Spectre 13-V series laptop. In component-level micro-soldering and laptop repair, this schematic is the foundational tool required to diagnose power failures, signal drops, and short circuits on this highly integrated Core i5/i7 7th Generation hardware architecture.

A shorted ceramic capacitor is a frequent issue on thin-and-light motherboards due to high thermal stress.

The dual-chip or high-capacity SPI flash architecture on this board frequently suffers from firmware corruption, especially after interrupted Windows updates or improper shutdowns.

Integrated Intel HD Graphics, with some premium variants featuring an NVIDIA GeForce 940MX or MX150 discrete GPU with dedicated VRAM.

Pay attention to symbols like # or _N at the end of a signal name (e.g., PLTRST# ). This denotes an active-low signal, meaning the line must drop to 0V to be considered active.
