Schematic in PDF form for the Toshiba Satellite 1200 notebook. The file name gives only the model, with no motherboard number or revision, so compare the board markings on your unit against the title blocks inside the document before trusting it. A circuit diagram of this kind lets a technician follow power rails from the adapter input through the charger and regulators, trace signals between chips and find which components sit on a shorted line. Any PDF reader opens it, and text search helps locate part designators quickly.
