Boardview for Compal board LA-4101P at revision R05, labelled JAL and UMA, meaning the integrated-graphics version without a discrete GPU. LA-xxxxP numbers are Compal's ODM pattern, used for laptops sold by several brands. A boardview lets you locate parts, follow nets between pins and find test points while probing for shorts or missing rails. After unpacking, open it in a viewer such as OpenBoardView, FlexBV or Boardviewer, and confirm the LA number and revision on the PCB match since UMA and discrete layouts differ.
