ABSTRACT:
A method for reducing instantaneous current on startup is applicable to an electronic device with a management controller. The management controller is electrically connected to a startup processing module of the electronic device such that operations of fans equipped in the electronic device can be controlled via this electrical connection relationship. When the electronic device is turned on, operations of the fans in the electronic device are disabled by the startup processing module. Then, when power is detected by the management controller, the smallest amount of current possible for operations of the fans for heat-dissipating purpose is generated by the management controller. Finally, hardware components in the electronic device are initialized by the management controller. The above method solves the problem of system instability due to large instantaneous current on startup in the prior art.
