La-e801p Rev 2.0 Schematic [new]

A critical chart showing the order in which voltages must turn on.

Understanding the power rails is the most critical aspect of troubleshooting a dead or malfunctioning LA-E801P motherboard. The board utilizes a step-down buck topology to convert the 19V primary input voltage into the lower voltages required by the digital logic circuits. 1. The Primary Input Rail ( +19V / VIN )

: Measure the physical pins of the power port connector to confirm arrives safely from the adapter.

Boardview software allows you to search for PR301 and highlights its exact location.

Check for the linear regulator output pins ( +3VLP / +5V_LDO ). These low-current lines must read perfectly flat voltages.

: Pinpoint the twin input isolation switches near the charger chip. Check for a short circuit across source-to-drain pins. Verify Always-On IC : Test the output inductors for . If these voltages read , verify if the controller has received its +Bpositive cap B input voltage. 2. Motherboard Turns On with Spin but No Display A critical chart showing the order in which

If you are holding a faulty Lenovo IdeaPad 320 or a similar laptop that relies on the Compal CSL50/CSL52 motherboard, you are likely dealing with the logic board. For advanced hardware repair and diagnostics, tracking down the la-e801p rev 2.0 schematic and its corresponding Boardview file is the ultimate key to reviving the system.

: Detailed diagrams of the G3, S5, S3, and S0 power states, including the +3VALW and +5VALW standby rails.

: Delivers stable power to the DDR4 memory slots. Boardview software allows you to search for PR301

The Compal LA-E801P (often labeled as C5V01) is a widely deployed laptop motherboard found across several generations of Acer Aspire and Nitro series laptops, most notably the Acer Aspire A515-51 and A515-51G. Laptop repair technicians, hardware enthusiasts, and reverse engineers heavily rely on the schematic diagram and boardview files for this specific revision (Rev 2.0) to diagnose complex hardware failures, trace power rails, and perform component-level micro-soldering.

: Because the 19V power rail isn't passing through to the rest of the board, technicians need the schematic to identify which MOSFET is blocking the current. Common "Villains" :

Based on hundreds of repair logs, here are fixes you can perform using this document:

Based on empirical repair data for the Compal LA-E801P Rev 2.0 board, several failures occur with high frequency: Symptom 1: Laptop is Completely Dead (No LEDs, No Charging)
