RAR archive of 1.12 MB for the Compal LA-6855P motherboard at revision 1.0. The name does not list the contents, though files of this kind usually hold the schematic and sometimes a boardview. Compal assigns LA- numbers to its notebook mainboards, which ship under several laptop brands. Use the material to follow rails from the charger through the system and CPU regulators, locate test points and diagnose no-power or no-display faults. Extract it with WinRAR or 7-Zip and confirm the PCB label reads LA-6855P R1.0.
