RAR archive whose name refers to X133TE, revision marker E, the token APL and LP3B256, with version V2.0. APL most likely means an Apollo Lake platform and LP3B256 suggests an LPDDR3 memory configuration, but the name does not say which brand or device this is. At 4.55 MB it probably holds a firmware image or board files for a small budget laptop or tablet. Unpack it and inspect the contents before use, and compare the board marking and memory chips on the unit with the identifiers in the name.
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 @biositechyangiyer. Enginerys does not host this file.
