La-e801p Rev 2.0 Schematic -

The first MOSFET (PQA1) is a frequent failure point. Technicians often find that 19V reaches the first MOSFET but does not pass through because the gate signal is missing or there is a short on the output side.

Boards like this contain hidden test points that are not labeled on the silk screen. The Rev 2.0 schematic reveals the exact names (e.g., TP3107 for +VCC_CORE ) and expected voltage values, allowing you to probe with a multimeter or oscilloscope. la-e801p rev 2.0 schematic

Available in both UMA (Unified Memory Architecture) and Discrete (dedicated GPU) versions. Common Faults and Diagnostic Steps The first MOSFET (PQA1) is a frequent failure point

The board is responsible for two critical functions: The Rev 2

This specific motherboard is most commonly found in:

No. The service manual from Dell shows how to replace the hard drive, RAM, and keyboard. The schematic shows the actual circuitry. They are completely different documents.

Through years of repair data, several failure patterns have emerged for this revision. Here is what to look for:
