La-e801p Rev 2.0 Schematic 〈Linux PLUS〉
Before diving into the schematic, you must understand the board's layout. The LA-E801P is an Intel-based board, typically paired with:
The "Rev 2.0" designation is critical. Dell and Compal (the OEM manufacturer) released multiple revisions of this board. A schematic for Rev 1.0 may have different resistor values, missing test points, or altered power rails compared to Rev 2.0. Always ensure your schematic matches the revision printed directly on the PCB.
LA-E801P Rev 2.0 schematic is a critical document for repairing HP 15-BS series laptops, which use the Compal CSL50/CSL52 motherboard architecture
. While a Rev 2.0-specific PDF is difficult to find publicly, technicians often rely on the Rev 1.0 schematic la-e801p rev 2.0 schematic
for most power rails and signal paths, as the core engineering remain similar Key Technical Details Motherboard Model: Compal CSL50 / CSL52 Common Applications: Primarily found in laptop series Major Components: Intel Kabylake/Skylake (often U-series) Dual-channel DDR4 slots Integrated UMA or Discrete GPU options Common Repair Points
Technicians working on the Rev 2.0 board frequently encounter "no power" or "no lights" issues
. Key areas to check based on community repair logs include: Primary Power Stage: Before diving into the schematic, you must understand
Verify 19V at the first input MOSFET. If it's blocked, check for shorts on the (a dual transistor often marked Power Rails: Confirm the presence of 3.3V and 5V standby voltages Component Testing: Low resistance on coil may indicate a fault in the PCH or related power ICs Where to Find the Schematic

The LA-E801P Rev 2.0 appears to be a power distribution and signal management board, often found in integrated display systems or industrial control stacks. The Rev 2.0 designation suggests this is a second iteration, likely addressing noise suppression or connector durability issues found in earlier revisions.
The features outlined above provide a general idea of what might be included in a laptop based on the LA-E801P Rev 2.0 schematic. Actual features can vary based on the specific laptop model, manufacturer customizations, and market region. This list serves as a reference for understanding the capabilities and design considerations of laptops built around this platform.
