A method, an apparatus, and a system are provided for automatically repairing a smart device in the field of computer technology. In the method, the apparatus receives a fault detection request transmitted by the smart device, the fault detection request carrying at least one current value of at least one preset parameter item of the smart device. The apparatus determines whether the at least one current value is within a preset range according to a first value characteristic. When it is determined that the at least one current value is within the preset range, the apparatus obtains first fault repair information corresponding to the first value characteristic from a correspondence table.
