RAR archive of 5.65 MB for a Philco 14-inch device, probably a notebook, with the name marked 14 I and a duplicate-copy suffix. No board number, revision or file contents are given, so the material inside could be schematics, boardview or firmware. Extract with WinRAR or 7-Zip and review each file before relying on it. Philco laptops are often built on generic ODM boards, so match the board code printed on the PCB with any document inside before tracing circuits or flashing firmware.
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 @oficinacomputadores. Enginerys does not host this file.
