La-h103p Schematic Portable Jun 2026

If you are reverse-engineering this board, trace the 3.3V rail first. Almost all peripheral components (buttons, LEDs, logic levels) interface with this rail. If the board is dead, check the main DC-DC buck converter (usually an 8-pin SOIC package) before suspecting the main scalar IC.

The LA-H103P is a reference PCB (Printed Circuit Board) number, typically associated with and Vostro series laptops (e.g., Inspiron 14 5480, 5490, or Vostro 5490). This board features 8th, 10th, or 11th generation Intel Core processors (Whiskey Lake or Comet Lake-U) and relies entirely on USB-C Power Delivery (PD) for charging—meaning there is no traditional DC jack. If you are reverse-engineering this board, trace the 3

If you are using the schematic to fix a "no power" issue, technicians typically focus on: 3V/5V Standby Rails: : Typically an UMA (Unified Memory Architecture) design

Supports Intel 10th Gen "Ice Lake" CPUs, including i3-1005G1, i5-1035G1, and i7-1065G7.

On models using USB-C for power, the controller chip (often a TPS variant) can fail due to surges. How to Use the LA-H103P Schematic for Repair
