PDF schematic for the Compal LA-A972P laptop motherboard, 1.19 MB. The file name gives only the board identifier, so brand, model and revision are not stated. Compal uses LA-numbered codes for boards it manufactures as an ODM for many notebook brands. Technicians use such diagrams to follow rails, check the standby and main power circuits, and identify the parts around a suspected short. Compare the silkscreened board number and revision with the drawing before replacing parts.
