Archive for the Lenovo E40 notebook, 1.32 MB in RAR format, with no board number, ODM or revision in the name. Its size suggests a schematic document, possibly with extra material, but the contents are not stated and should be checked after unpacking with 7-Zip or WinRAR. Before using any diagram inside for fault finding, read the board code printed on the mainboard and compare it with the title block of the schematic. E-series models were produced on more than one platform, so the match matters.
