Small schematic PDF, only about 76.3 KB, for the Acer Aspire T5000, labelled with Usopp SLS and Quanta in its name. Quanta is a laptop ODM and SLS is probably part of the project code, so the drawing follows Quanta conventions. Given the very small size, it may hold only a few pages, such as a block diagram or excerpt, rather than a complete board schematic, so open it to check coverage. Confirm the board marking on the PCB before relying on it for tracing rails or locating parts.
