RAR archive for the Toshiba Satellite L500, 1.83 MB, with no board number or contents given in the name. L500 notebooks were produced on more than one motherboard design, so open the archive and read the board code in the drawing title block, then compare it with the label on your PCB. Assuming it is a schematic set, it can be used to trace supply rails, check the charger and EC power signals, and locate parts when hunting a short or missing voltage.
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 @alischematics. Enginerys does not host this file.
