Which (e.g., is 19V present?). If you have a multimeter or oscilloscope handy. AI responses may include mistakes. Learn more
Check the two DC-in MOSFETs near the charging port. They often short, preventing the 19V rail from reaching the rest of the board.
Finding the correct schematic and boardview is the first step toward a successful board-level repair. Understanding the LA-H103P Platform lah103p schematic new
Locate specific pads to measure signals like RSMRST# or PWRBTN# . Key Areas to Check on LA-H103P
The LA-H103P (also known as the GDI4A) typically supports Intel 10th or 11th Gen processors (Ice Lake or Tiger Lake) or AMD Ryzen alternatives depending on the specific sub-model. Combined CPU/PCH (SoC) design. Which (e
The LA-H103P is a motherboard model commonly found in Dell Inspiron 15 (3501, 3505) and 14 (3401, 3405) series laptops. If you are looking for the "new" or latest version of the schematic for a repair, you are likely dealing with a "no power" or "no display" issue.
💡 If you can't find a component labeled on the board, search the schematic for the "PU" (Power Unit) or "PQ" (Power Quarter/Transistor) number to find its functional group. If you'd like, I can help you further if you tell me: Learn more Check the two DC-in MOSFETs near
Map out 19V (B+), 3.3V/5V Alw, and RAM voltage.
Use a lab power supply to inject voltage safely if you find a short circuit.
