Indexed under schematics, this 70.4 KB PDF is named only 1SS308, without any laptop model, board number or revision. 1SS is the Japanese JIS prefix for small-signal diodes, a series closely associated with Toshiba, so the file probably holds a component datasheet. Use it to check package dimensions, pinout, marking code and maximum ratings when a diode on a signal or supply path is suspected. Confirm the marking on the board part matches before relying on these figures for a substitution.
