RAR archive for the Dell Inspiron 700m, a compact 12-inch notebook, weighing 865 KB. The name gives only the model, so the contents are unspecified; at this size it most likely holds a schematic or boardview rather than a firmware image. Extract it and check what is inside before planning a repair. Whatever the documents turn out to be, compare the board number silkscreened on the motherboard with the one in the files, since Dell often used several board revisions for one model and rail names or part references may differ.
