Compal LA-5221P notebook board schematic, revision 0.1, supplied as a 2.03 MB PDF. Compal is an ODM, and its LA numbers identify the board itself rather than the laptop brand, which the name does not state. The document helps trace power rails, follow the power-on sequence, find the BIOS flash and EC, and identify which component drags a rail to ground. As an early 0.1 revision, compare it with the actual board and confirm the LA number and revision on the PCB before relying on details.
