Compal LA-9982P schematic set at revision 3.0, in a 2.08 MB RAR archive. The name states only the board number and the revision; laptop brand, model and chipset are not given. A 3.0 revision indicates a mature, later-stage design, but boards from earlier runs may differ, so compare with the silkscreen. Once extracted, the diagram helps trace power rails, follow the power-up sequence, locate the EC, BIOS flash and voltage regulators and find the source of a short. Compal prints these LA-codes on its PCBs for many notebook brands.
