PDF schematic for the Dell Alienware M17 R3 gaming laptop, Compal motherboard LA-J521P, revision R10, compressed into a 4.73 MB RAR archive. Boards with the LA- prefix are designed by Compal for Dell. The circuit diagrams help when tracing GPU and CPU power stages, charger and battery logic, and the power sequencing signals that decide whether the board starts. Any PDF reader opens it; use the search function for net names and confirm the PCB revision matches before measuring.
