Compal boardview for motherboard LA-D801P, revision 1.0, with no laptop brand or model given in the file name. The LA-xxxxP code follows Compal's standard numbering, used on notebooks it builds for Acer, Dell, Lenovo, HP and others, so look up the model by that code. The 7.31 MB RAR holds layout data for OpenBoardView, FlexBV or comparable viewers, useful for tracing rails, finding test points and isolating a shorted capacitor. Make sure the code and revision on your PCB match exactly.
