Typically driven by an ISL or Texas Instruments (BQ series) management chip. This IC monitors AC adapter identification (PS_ID for Dell), controls the isolation MOSFETs, and manages the battery charging current.

The is the definitive blueprint for repairing the Lenovo IdeaPad S340-15ILL laptop . Manufactured by Compal, this specific motherboard architecture handles Intel 10th Generation Ice Lake processors and critical power rails. This comprehensive guide covers everything from power rail mapping to common circuit failures on this specific board revision. Motherboard Architecture Overview lah103p schematic new

: A low-resistance shunt resistor monitors total system current draw. Always-On Rails (+3.3V_ALW / +5V_ALW) Typically driven by an ISL or Texas Instruments

This article dives deep into the newly released, verified revision. We will break down its internal architecture, explain its role in current sensing, provide a pin-by-pin functional analysis, and discuss how this new documentation differs from the fragmented, often incorrect diagrams circulating online.
