The (often labeled as CSL50, CSL52, or CKL50) is a Compal motherboard commonly found in HP 15-bs series laptops.

While Rev 1.0 schematics are more widely available for download, finding a dedicated Rev 2.0 manual can be difficult. Technicians typically use the Rev 1.0 schematic as a primary reference, as the core power rails and component architecture remain largely the same across revisions. Key Technical Details for LA-E801P Rev 2.0

If you are troubleshooting a Rev 2.0 board, keep these specific component IDs and measurements in mind:

Main Power Rail (19V): Verify 19V at the drain (pin 8) of PQB12 to ensure the DC-in circuit is functional.

Critical Fault Point: A common failure in Rev 2.0 is the PQA1 chip (a dual PE642DT transistor). Resistance-to-ground measurements at PLA1 (the inductor) and PQB12 (pin 8) can help determine if a PCH or charging circuit fault exists.

Power Button: You should typically see 3.3V at the power switch connector. Resources for Repair
