Compal-style schematic for what appears to be board LA-B092P at revision R10, dated 0219C, labelled UMA for MP, meaning the integrated-graphics version released for mass production. The 1.19 MB PDF states no brand or model, so check the board label on the PCB. UMA builds lack the discrete GPU section, so discrete-graphics boards may differ. Use it to trace power rails, locate components and test points, and follow the power sequence when a laptop will not start.
