PDF schematic for a Compal DAL30 board carrying the LA-2154 number; the name gives no laptop brand or model. Compal identifies its mainboards with LA-prefixed codes printed on the PCB silkscreen, so match LA-2154 on the board before use. The diagram set covers power sequencing, voltage regulators, the chipset, memory and the I/O connectors, which helps with measuring rails, finding missing enable signals and identifying parts by reference. It opens in any PDF reader and is 1.16 MB in size.
