This write-up covers the Compal LA-E801P Rev 2.0 (CSL50/CSL52)

The schematic was drawn with a clarity that bordered on art. The nets were colored to indicate voltage levels. The bypass capacitors were placed not just symbolically, but in positions that indicated physical proximity to the IC pins.

The Rev 2.0 schematic is crucial because it offers improved component mapping over earlier revisions, specifically addressing common power-related failures. LA-E801P Rev 2.0 Schematic & Boardview Highlights Compal CSL50/CSL52 (LA-E801P) 2.0 (Confidential) Common Applications: HP Pavilion 15-bs, 15t-bs, 250 G6 (KBL-U/SKL-U)

The LAE801P Rev 2.0 schematic offers several key features and functionalities, including:

6. CONCLUSION

The assessment confirms that the LAE801P Rev 20 Schematic is significantly "better" than its predecessors.

9. Downloads & References

Note: Rev 2.0 often uses a dedicated PMIC for these rails. Check for an enable (EN) signal from the EC if the rails are missing. 3. The Power-On Sequence

If your board has no lights (no power), start with these checks found in the schematic: Input MOSFETs (PQA1/PQB12):
