PDF schematic for a Compal laptop mainboard on the CSL50 platform, board number LA-E791P, revision 1.0. The name does not identify the laptop brand. A full circuit diagram like this lets you follow the power-on sequence, trace rails from the charger circuit to the CPU and memory, and look up component values and signal names. Any PDF viewer opens it. LA-xxxxP is Compal's numbering format; check that the board number and revision on the PCB match before replacing parts based on it.
