Abstract

A method, a system and a server for self-healing of an electronic apparatus are provided. In the method, the components installed in the electronic apparatus are sequentially called and checked to update each component. Then, a self-diagnosis is executed on the electronic apparatus to produce a diagnosis result and the diagnosis result is sent to a server. The server analyzes the diagnosis result, accordingly sets at least one policy for healing the electronic apparatus and sends the at least one policy back to the electronic apparatus. The electronic apparatus transforms the policy into at least one rule adapted for itself and performs the self-healing according to the rules.
