ZIP archive for Compal board LA-F951P, around 7.5 MB. The name gives no laptop brand, model or revision, so identify the machine from the board and confirm what the archive holds after extraction; packages of this size often include a schematic and possibly a boardview. Compal uses the LA-xxxxP numbering, printed on the PCB, for boards it builds for brands such as Dell, HP, Lenovo and Acer. The documents help trace power rails, find components and test points and diagnose shorts.
