Dell laptop schematic for the Compal LA-9934P motherboard at revision 1.0, provided as a PDF in a 3.43 MB RAR archive. The name does not state the Dell model, but the Compal code printed on the PCB identifies the board directly, so check that it matches. The drawings let you trace the charger and system power rails, follow the power-on sequence, find the EC and BIOS flash and locate shorted parts. A working BIOS dump for this board is also catalogued.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @schematicslaptop. Enginerys does not host this file.
