Part number 1SS345 is the only information in this 58.3 KB PDF name, so no laptop, board or revision is identified. The 1SS code belongs to the JIS numbering for small-signal diodes used mainly by Toshiba, pointing to a component datasheet despite the schematic label. Open it in any PDF viewer to read electrical limits, package drawing and marking. That helps when checking a diode found short or open in diode mode and choosing a substitute with equal or better reverse voltage and current ratings.
