La-e801p Rev 2.0 Schematic _top_ Jun 2026

VIN passes through the entry protection MOSFETs.

The primary voltage distribution rail originating from the DC jack or the battery pack (via the charging circuit).

The only safe way to inject voltage into a shorted rail to find out which component is heating up (commonly known as "smoke testing" or using thermal cameras).

I'm looking for the schematic for the LA-E801P Rev 2.0 motherboard. I've searched online, but I couldn't find a reliable source. Has anyone come across a download link or knows where I can obtain it? la-e801p rev 2.0 schematic

In the schematic, look for signals like ACIN (AC Adapter Detect), (Lid switch), and

2.0 (Commonly documented as Rev 1.0, but Rev 2.0 shares significant architecture) Application: HP 15-BS Notebook series Power Architecture & Components

The schematic will show the inductor (PL..., e.g., PL401) for these rails. A common diagnostic trick is to desolder or measure the resistance to ground at these inductors. If the resistance is very close to Ω (e.g., 0.2 Ω), a capacitor further down the line is shorted. 3. Power Good (PWR_GD) and the SIO Chip VIN passes through the entry protection MOSFETs

Locating schematics and boardviews requires visiting community-driven hardware repair forums and platforms. Reputable repositories like or Rossmann Repair Group Forums are excellent places to search for specific Compal board files. Additionally, many independent technicians share these exact PDFs on dedicated Telegram channels and archive sites.

: Community repositories like schematics|boardviews Telegram frequently share both the PDF schematic and the .BRD boardview files.

Disclaimer: Laptop repair requires experience with micro-soldering and diagnostic tools (multimeter, oscilloscope). Always disconnect the battery and power supply before working on the board. I'm looking for the schematic for the LA-E801P Rev 2

The BIOS for the CSL50/CSL52 LA-E801P Rev 2.0 is often stored on a flash memory chip and works in conjunction with the ENE KB9022Q embedded controller (EC). This combination of chip and firmware is critical for basic functions like power management and keyboard control.

Without the schematic, repairing the LA-E801P is a guessing game. With it, it becomes a science. Here are the top three failures I see on the bench and how the diagram guides the fix:

Integrated Intel U-LV CPU (BGA package) handling both processing and Platform Controller Hub (PCH) operations.

), the EC assumes the laptop screen is closed and ignores the power button entirely.

This level of logical deduction is impossible without the schematic.
