Zip archive for the Acer Aspire E3-112M notebook, 2.71 MB in size. The name identifies only the laptop model and gives no board number, revision or hint about whether the contents are a schematic, boardview or firmware dump, so open it and inspect the files before use. Packages of this size for Acer models usually hold repair documents or a BIOS image. Before relying on anything inside, compare the motherboard number silkscreened on the PCB with any number in the documents, because one model name can ship on different boards.
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 @laptopbios21. Enginerys does not host this file.
